Supplied cable entry flanges for flange openings

The following cable entry flanges are supplied ex works for the flange openings

	Cable entries in enclosure roof	Cable entries in enclosure base
Wall-mounted enclosure	1x FZ402 at top for each field	1x FZ408M, remaining fields with FZ406M
Floor standing enclosure with base plinth	1x FZ402 at top for each field	No flange at bottom ex works ^1

^1 floor standing enclosure at bottom: To comply with protection type IP55 and protection class CL II, insulated insertion flanges or sealing plates FZ435A must be inserted at the bottom.

The cable entry flanges can be opened or closed by turning the sash lock by a 14 revolution. The flanges can be locked against unauthorised opening using additional accessories.

Retrofitting flange openings for an enclosure depth of 400 mm

In addition to the flange openings, enclosures with an enclosure depth of 400 mm offer additional pre-punches at the top and bottom for creating additional flange openings as needed. These flange openings can be equipped with cable entry flanges. The same flanges can be used here as those used in the standard openings.

Step Action

1

Cut out the plastic panels inside the enclosure using a cutter knife. Never knock out the plastic panels.

2

Then, knock out the underlying pre-punch in the cover plate / floor plate using a hammer.Make sure to precisely knock out the pre-punches to avoid damaging the housing.The high IK10 impact protection of the enclosure also requires a stable pre-punch. A certain degree of effort is therefore required for knocking out the pre-punches.Result:An additional flange opening is created. A cable entry flange can be used.

4.6.1 Universal cable entry flange FZ402

Wall-mounted enclosures and floor standing enclosures are supplied with a flange opening at the top and a cable entry flange FZ402 for each field:

5 Internal extension and assembly

Note:

- Observe the manuals about the univers N internal extension system from Hager.

5.1 Earthing concept for wall-mounted and floor standing enclosures, protection class CL I

• The housing and all other conductive parts in the earthed enclosures with protection class CL I must be connected to the equipotential bonding.
  The necessary cables are included in the scope of delivery for this: 2 x 90 cm green / yellow cable with cable lug
• Since the mounting rails are fastened insulated in the enclosure, it must be ensured that all mounting rails are connected via conductive modules or cables or earthing accessories, such as UZ010 / UZ020.
  The continuity of the earth connection of the individual mounting rails have been tested via conductive modules (such as, uninsulated mounted DIN rail), is sufficient and permissible.

Note on using the univers N internal extension system:

• The door is insulated against live parts by the covers. It is therefore not essential to earth it with a cable.
• An earthing cable for the door is supplied when the enclosure is delivered. It is used for installing devices in doors. The earthing cable, however, is not intended for use as a protective conductor.
• When installing devices in doors, protective conductors must be dimensioned according to the rated current of the installed devices, as prescribed in the relevant standard, once the protective extra-low voltage value is exceeded.

5.2 Protective insulation for enclosures with protection class CL II

In enclosures with protective insulation, the mounting rails are fixed with insulation ex works.

According to EN 61439, mounting rails and other metal parts (such as, the door, housing, mounting plates) are not connected to the PE/PEN via an earthing conductor.

Note:

Enclosures with protection class CL II can be built back into protection class CL I by removing the insulation to the enclosures.

- Ensure a conductive connection of the carcass to the PE.

Ensuring protective insulation for floor standing enclosures of protection class CL II

- Floor standing enclosures of protection class CL II must also be closed in the floor plate with plastic flanges or FZ435A closing plates to ensure the protective insulation. IP55 does not depend on this.

5.3 Comply with protection type IP55

IP55

• 1st code number 5 "Protection against dust deposits (dust protection)"
• 2nd code number 5 "Protection against water jets"
• Use the cable entries and accessories from the distribution enclosure series on the enclosure to ensure protection type IP55.
• Make sure that the cables are inserted correctly through the cable entry flanges in the enclosure.
• Make sure that the enclosure is assembled level / on a plane. The floor standing enclosure with the base plinth is supplied without a flange in the floor plate. The protection type IP55 is verified under standardised testing conditions and when the unit is installed with a base plinth on an even surface.
• This result cannot be ensured on an uneven surface or with non-standardised air movement.
• We thus strongly recommend using flanges or alternative locks

When the door is open, the enclosure achieves protection type IP3X when the univers N internal extension system and Hager devices are consistently used.

5.4 Disassembling and assembling the doors

The doors are equipped with

• edge protection against scratches. Disassembled doors can thus be temporarily stored without any damage. The edge protection is fixed to the enclosure with hot glue and can be removed without leaving any residue after final installation.
• Hinge pins for one-person door assembly. The hinge pins can be pulled without any tools and are locked into the top position by the red locking pin. This makes it possible for one person to assemble and disassemble the door.

Hinge pin for fast door assembly / disassembly.

Important notes:

• Before disassembling the door, secure the enclosure against tipping over.
• Secure the door against unintentional closing. The door is not stable without any hinge pins.
• After the door is assembled, make sure that the hinge pins are locked. If not all hinge pins are locked, the hinge may be damaged.

Changing the door stop

The door stop can be changed by unscrewing the hinge on the opposite side. The holes for the hinges are available on both side and closed with plastic caps.

- Insert the plastic caps on the unused side. This is essential for maintaining the protection type.

5.5 Mounting rails

The mounting rails can be fastened in the grid dimension 12.5 mm
- In the enclosure with a depth of 275 mm, at 6 different depths,
- In the enclosure with a depth of 400 mm, at 16 different depths.

- To make it easier to arrange the mounting rails, the positions are marked in the plastic panels.

Enclosure dimensions for univers N internal extension system measured at the mounting rail in the front or rear position:

Assembling the mounting rails

To use the mounting rails in the enclosure, the mounting rail fixings / mounts UT90J or UT90G must be used:

• UT90J: For fastening the mounting rails at the same level
• UT90G: For fastening the mounting rails at a different level

The mounting rail fixings / mounts can be moved to different depths without any tools.

Mounting rail fixings / mounts UT90J:

The UT90J mounts are fastened as standard at position 3 in the enclosure ex works.

Mounting rail fixings / mounts UT90G:

Connectors UT12L / earth connecting bracket UZ00VL

- Connectors UT12L are used to increase the stability of the mounting rails and establish the connection via the mounting rail connection set UT12HSV (U plates) or the earth connecting bracket UZ00VL:

Technical diagram showing mechanical assembly with mounting brackets and a separate bracket with bolts (no text or symbols)

Earth connecting bracket UZ00VL

- For the conductive connection of 2 mounting rails

- For increasing the mechanical stability

Ensure touch protection depending on the mounting rail position

- Extend the touch protection depending on the mounting rail position. The mounting rail fixing is assembled at position 3 or 4 for enclosures with of a depth of 400mm . If the mounting rails are positioned lower in these enclosures, then accessory parts may be used for extending the lateral circumferential contact protection. Hager offers contact protection cover FZ851.

There are always 3 holes in the middle of the mounting rails at different heights (1 x middle and ± 150 mm) for fastening the mounting rail on the retaining rail.

- Use the supplied countersunk screws for assembling the mounting rail on the retaining rail. (Normal screw heads would otherwise prevent the assembly of a module at this position.)

Observe the assembly order:

Step Action

1 Position the retaining rail in the enclosure.

2 Fix the mounting rails on the retaining rail. Use the supplied countersunk screws.

3 Assemble the univers N modules on the mounting rails.

5.7 Crossbar

5.10.1 Busbar gland: Arrangement and dimensions

Arrangement and dimensions of the pre-punches for busbar glands

Technical line drawing of an open electrical cabinet with internal components and mounting brackets (no text or symbols)

The distribution enclosures are equipped with side pre-punches for busbar glands.

Example on figure on the left:

• Enclosure height 1850 mm:
• Enclosure depth 275 mm

The number and position of the side pre-punches vary depending on the enclosure depths and height:

Enclosure depth 275 mm: Side pre-punches for busbar glands

Enclosure depth 400 mm: Side pre-punches for busbar glands

Opening pre-punches: Assembly instructions

Pre-punches for the busbar gland must be knocked out as needed. The high IK10 impact protection of the enclosure also requires a stable pre-punch. A certain degree of effort is therefore required for knocking out the pre-punches.

- With the enclosure featuring protection class CL II, open the protective insulation on the pre-punches inside before knocking them out. You thus avoid damaging the side insulation.

- Make sure to precisely knock out the pre-punches to avoid bending the side panel.

11 Glossary

Degree of pollution

The degree of pollution defines the ambient conditions of a switching device. If the switching device is installed in an enclosure, the ambient conditions within the enclosure apply. The degree of pollution according to EN 61439 refers to the ambient conditions that are intended for the switchgear and controlgear assembly.

The four defined degrees of pollution are used to assess the clearances and creepage distances in the microenvironment. The degree of pollution 3 is defined as conductive pollution or dry, non-conductive pollution, which is expected to become conductive due to condensation. The degree of pollution 2 is defined only as non-conductive pollution in which, however, temporary conductivity can be expected due to condensation.

Distribution boards for operation by ordinary persons (DBO) according to EN 61439-3

DBO. According to EN 61439-3, a DBO is a distribution boards for operating by ordinary persons (Distribution Board intended to be operated by ordinary persons). This is a switchgear and controlgear assembly for distributing electrical energy for applications in residential areas and other locations where operation is intended by ordinary persons.

The distribution boards are manufactured and tested for operation by ordinary persons (DBO) according to EN 61439 Part 1 and Part 3. Part 3 of the standard 61439 defines the specific requirements for distribution boards for operation by ordinary persons (DBO).

A switchgear and controlgear assembly that allows operation by ordinary persons must include a type plate that specifies the standard EN 61439-3 (VDE 0660-600-3) as the applied standard.

Characteristic features of such a switchgear and controlgear assembly:

① They are intended for operation by ordinary persons, including switching operations and changing fuse inserts. They are applications in residential areas or similar household applications in a functional building.
② The outgoing circuits contain short circuit devices that are intended for operation by ordinary persons. Additional information is provided in section 8 of EN 61439-3.
③ The rated voltage against earth is maximum 300 V alternating current.
④ The rated current ( I_ne ) of the outgoing circuit is maximum 125 A; the rated current of the switchgear and controlgear assembly ( I_nA ) is maximum 250 A.
⑤ The switchgear and controlgear assembly is intended for distributing electrical energy and may also contain controlling and signalling devices to do this.
⑥ The switchgear and controlgear assembly is closed and fixed.
7 The switchgear and controlgear assembly can be provided for indoor or outdoor installation (for distribution enclosures FR and FS: indoor installation). The protection type of a DBO for indoor installation must be at least IP2XC. The IK code against mechanical influence must correspond to at least IK05 for indoor installation. At least the degree of pollution 2 applies.

Additional information is provided in EN 61439 Part 1 as well as Part 3.

^1 About the characteristic feature 4 (rated current of outgoing circuit max. 125 A / rated current of switchgear and controlgear assembly max. 250 A):

The current standard EN 61439-3 only defines the maximum rated currents I_nc and I_nA . No determinations have been made about the rated currents of the operating equipment in the incoming unit of a DBO. The maximum permissible I_nA of 250 A can thus also be routed via a 400 A circuit breaker. The following requirements apply:

• The rated current of the switchgear and controlgear assembly (I nA) must be limited to 250 A.
• Operation of the circuit breaker by ordinary persons must be effectively prevented (use locking devices).
• The setting or calibration of the circuit breaker must be visible. The calibration cannot be changed without the deliberate use of a tool / key.

EN 61439 / IEC 61439 / VDE 0660-600

The EN 61439 standard series replaced the EN 60439 standard series. The EN 61439 standard series has the goal of harmonising the rules and requirements for low-voltage switching equipment combinations.

The valid part of the EN 61439 standard series is always the applicable part of the standard, e.g. EN 61439-6 for busbar trunking systems (busways) together with Part 1 of the standard (EN 61439-1).

Power switchgear and controlgear assembly (PSC) according to EN 61439-2

PSC power switchgear and controlgear assembly. As a low-voltage switchgear and controlgear assembly, it distributes and controls electrical energy for all load types according to EN 61439-2. Intended for industrial, commercial and similar applications, which are not intended to be operated by an ordinary person.

It is not prohibited, however, to install in an area that can be accessed by ordinary persons. It must, however, be ensured that operation by ordinary persons is prevented.

Protection type / IP degree of protection

For each switchgear and controlgear assembly, the protection type with the IP code is specified according to IEC 60529 and verified according to EN 61439

• with regard to protection against contact with active parts and preventing solid foreign bodies from entering the system,
• with regard to preventing water from entering the system.

The protection type is important for ensuring protection against electrical shock. The protection type applies to jacketings, covers and housings. The protection type is specified by two code numbers of the IP protection type and optionally an additional letter.

• The first code number (0-6) indicates the protection against solid foreign objects from entering the system and the protection against contact with dangerous parts.
• The second code number (0-8) indicates the protection against water from entering the system.
• The additional letter (A-D) indicates the protection against contact with dangerous parts.
