Frequently Asked Questions - VM202K HAGER

What does Hager VM202K voltage monitor do?

The Hager VM202K monitors the mains voltage and provides protection by disconnecting the load if the voltage exceeds or drops below safe thresholds.

How do I install the VM202K?

Install on a 35mm DIN rail. Connect the input phase (L) and neutral (N) to the device, and the output to the load. Ensure the supply is turned off before installation.

What are the voltage thresholds of the VM202K?

The typical thresholds are 253 V AC for overvoltage and 207 V AC for undervoltage. These may vary slightly by unit.

How does the LED indicator work?

A green LED indicates normal operation, red LED indicates a fault (over/undervoltage), and if the device has tripped, the output is disconnected until the voltage returns to normal.

How to reset the VM202K after a fault?

The device automatically reconnects when the voltage returns to normal limits for a defined period (typically a few seconds). No manual reset is required.

Is the VM202K compatible with single-phase or three-phase systems?

The VM202K is designed for single-phase systems (230 V AC). For three-phase monitoring, use three separate units or a dedicated three-phase monitor.

What load can the VM202K handle?

The device is typically rated for 20 A continuous load. Check the specific product datasheet for exact ratings.

Can I use the VM202K in a wet environment?

No, the device has an IP20 rating, meaning it is not protected against moisture. Install in a dry indoor location or in an appropriate enclosure.

What certifications does the VM202K have?

It complies with IEC 60669 and IEC 60947 standards, and is RoHS compliant.

Is the VM202K replaceable without professional help?

Replacement should be carried out by a qualified electrician due to the risk of electrical shock and the need for correct wiring.

Design 30 Consumer Unit Instructions/Data Sheet

This Consumer Unit and Hager devices conform with the following standards:

Consumer Unit: BS EN 61439-3 including Annex ZB.

Switch-disconnectors: BS EN 60947-3.

Residual Current Circuit Breaker (RCCB): BS EN 61008-1

Residual current operated circuit breaker with integral overload (RCBO): BS EN 61009-1

Miniature Circuit Breaker (MCB): BS EN 60898-1

Installation Instructions:

All product(s) must be installed by a suitably competent electrician Giving consideration to their intended use and in accordance with the current edition of BS 7671 (IET Wiring Regulations).

The Electricity at Work regulations and the Health and Safety at Work Act shall be complied with.

Only equipment and arrangements specified in Hager's technical documentation / catalogue shall be used.

Install in the horizontal plane only.

For guidance when making connections in a consumer unit electrical safety first /BEAMA document “Guidance for installers when making connections in consumer units” is available from hager.co.uk/63026.htm

Important notice:

To prevent potential overheating from loose connections the installer shall check connections are tight to the torque levels stated in these instructions prior to energizing this board. This check should include factory made connections which may have loosened in transit.

Good workmanship and proper materials must be applied by the installer. The cable entry method shall, as far as reasonably practical, maintain the non-combustable arrangement of the enclosure. Account shall be taken of these instructions.

Removal of front cover:

Easy fit front cover assembly allows the cover to be located at the top of the board and locked Into place that enables the cover to stay secure when replacing or removing during an installation.

Wall Fixing:

The units have multiple fixing points that will suit No.8 & No.10 screws

Cable entry facilities:

Where Electrical Knockouts are provided for top or bottom cable entry are sized and positioned to suit standard trunking i.e 100x50mm, 50x50mm & 40x25mm, grommet strip is provide to protect the cables when entering the board.

Rear cable entries shall enter thorough selected rear Knockout; once the Knockout is removed the cable protector bracket can be fitted to allow safe installation of the cables. Grommet strip lengths: Small EKO – 79mm, Large EKO – 127mm Rear EKO – 255mm

Note: Only BASEC approved cable should be used 1.0mm^2 to 16mm^2 for outgoing cables

Up to 35.0mm ^2 for incoming live cables

Single conductors below 1.5mm^2 need to be doubled back in the terminal bar.

Technical line drawing of an electrical switchgear assembly (no text or labels)

Incoming meter tails can be safely secured using the cable clamp system eliminating stress within the switch terminal.

Rear cable entries shall enter thorough selected rear knockout; once the knockout is removed the cable protector frame can be fitted in order to avoid any damage to the cable insulation or sheath during installation.

Guidance Notes:

The total load must not exceed the rating of the incoming device or the assigned assembly rating (InA) whichever is the lower. Each neutral and earth connection must correspond numerically to its outgoing way. Additional blanks (ref. JK01B) are available to cover spare ways.

A pack is provided to label this consumer unit, please consult us for spares or replacements.

Operating Instruction leaflet is provided overleaf. This leaflet should be left for the end user.

Single conductors below 1.5mm ^2 need to be doubled back in the terminal bar.

Consumer Units incorporating RCDs in TT systems should incorporate an S type (time Delayed) RCCB, e.g. 100 mA s-type RCCB. Alternatively a main switch with RCBO protection on all outgoing circuits should be used.

Precautions need to be taken to prevent faults to earth on the supply side of the RCD (as per BS7671 regulation 531.4.1)

Cable Access:

Cable access into the metal consumer unit must maintain the integrity of the non-combustable consumer unit so far as reasonably practicable. This can generally be achieved by the installer ensuring that cable access holes they make in the enclosure do not to leave gaps greater than:

• 1.0 mm for the horizontal top surface and
• 2.5 mm for all other surfaces of the enclosure that are accessible after installation.

For rear cable access, the minimum number of knockout(s) shall be removed and a cable protector fitted; see illustration above.

Tests on hager consumer units have indicated that there is no specific need for external fire rated cable glands or intumescent sealing in addition to the guidance below, with respect to achieving a non-combustible enclosure. However this does not preclude the designer/installer from using fire rated cable glands or external intumescent sealing should they consider necessary. Internal intumescent pads shall not be used.

Fitting Hager MCBs and RCBOs:

Only equipment and arrangements specified in Hager's technical documentation / catalogue shall be used.

1. Isolate the electrical supply from the consumer unit.
2. Remove the front cover.
3. Fully slacken the lower terminal of the device.
4. Fully open the bottom device clip (fig 1.)

fig 1.

1. Locate the device onto the din rail, and busbar. Ensure that the busbar tooth is within the device terminal cage.
2. Close the bottom device clip.
3. While holding the device firmly onto the busbar, fully tighten the lower terminal screw.
4. After fitting all outgoing devices and connecting all outgoing cables, please check the tightness of all cable connections. This should include all factory made connections, which may have loosened during installation or transit.
