2 Safety instructions

- The unit described is a subcomponent for integration into a system.

- The system architect is responsible for the safety of the system.

The system architect undertakes to perform a risk assessment and to create documentation in accordance with legal and normative requirements to be provided to the operator and user of the system. This documentation must contain all necessary information and safety instructions for the operator, the user and, if applicable, for any service personnel authorised by the architect of the system.

• Read this document before setting up the product and keep it during the entire service life.
• The product must be suitable for the corresponding applications and environmental conditions without any restrictions.
• Only use the product for its intended purpose (→ Intended use).
• If the operating instructions or the technical data are not adhered to, personal injury and/or damage to property may occur.
• In case of malfunctions of the unit, please contact the manufacturer. Tampering with the unit is not allowed.
  • Installation, electrical connection, set-up, programming, configuration, operation and maintenance of the product must be carried out by personnel qualified and authorised for the respective activity.
• Protect units, connectors and cables against damage.
• Replace damaged units, otherwise the technical data and safety will be impaired.

3 Intended use

The passive Process
Line power distributor can be used to supply IO-Link masters or AS-i modules and intelligent sensors/actuators.

Each supply connection (AS-i operation: AS-i / AUX; IO-Link operation: US / UA) has overcurrent detection (no shutdown).

• AC2950: 4-port power distributor
• AC2951: 8-port power distributor

The device is designed for use without a control cabinet in the food industry (indoor use).

The impedance of the power distributor corresponds to that of a standard slave in the AS-i network.

▶ Only use the unit within the limits of the technical data.

3.1 Safety symbol on the device

Safety symbol on the device:

▶ Adhere to the operating instructions for the safe operation of the unit.

4 Installation

4.1 Install device

▶ Disconnect the power to the machine during installation.
▶ Use a flat mounting surface for installation.

▶ Fix the unit to the mounting surface using 2 M5 mounting screws and washers, max. tightening torque 1.8 Nm.

5 Electrical connection

The device must be connected by a qualified electrician.

Observe the national and international regulations for the installation of electrical equipment.

Disconnect power.

Voltage supply according to SELV / PELV.

The IP rating of the overall system depends on the protection ratings of the individual devices, the applied connection elements and the corresponding protective caps.

The M12 connection parts in the device comply with the ingress resistance requirements of the standard EN61076-2-101. To adhere to the protection rating, only cables certified to this standard must be used. The system architect undertakes to ensure the ingress resistance of cables they have cut to length.

• Recommended maximum cable length: 5 m (AS-i operation)
• Recommended maximum cable length: 20 m (IO-Link operation)

Fasten the cable with a tightening torque of 0.6...0.8 Nm, observe the cable manufacturer's specifications.

▶ Carry out the fitting according to the indications of the cable manufacturer, a max. tightening torque of 0.8 Nm is permissible.
▶ During installation, place the M12 connector vertically so that the coupling nut will not damage the thread.
▶ Provide cables with a strain relief depending on the mounting conditions to avoid excessive strain on the installation points and the M12 connections.
▶ Ensure correct fit and proper assembly of the M12 connection parts. If these instructions are not complied with, the specified protection rating cannot be guaranteed.
▶ To connect the device, use M12 connectors with protection rating IP 65 / IP 66 / IP 67 or higher, depending on the requirements of the application.
▶ Use M12 connectors with gold-plated contacts.
▶ Cover the unused sockets with M12 protective caps, tightening torque 0.6...0.8 Nm.

In case of cables that are longer than 20 m (IO-Link operation), take the voltage drop and the necessary minimum supply voltage of 20 V into consideration.

5.1 UL applications

To connect devices, only use UL-certified cables belonging to category CYJV or PVVA with a minimum temperature of 80 °C (75 °C in case of a maximum ambient temperature of 40 °C).

5.2 Wiring

Voltage supply Power IN 0 (voltage input)

IO-Link operation	M12 connector(4 poles, A-coded)	AS-i operation
1: + 24 V DC (US)		1: AS-i +
2: GND (UA)		2: AUX -
3: GND (US)		3: AS-i -
4: + 24 V DC (UA)		4: AUX +

Voltage supply Power OUT 1...4 (AC2950) / 1...8 (AC2951) (voltage output)

IO-Link operation	M12 socket(4/5 poles, A-coded)	AS-i operation
1: + 24 V DC (US)		1: AS-i +
2: GND (UA)		2: AUX -
3: GND (US)		3: AS-i -
4: + 24 V DC (UA)		4: AUX +
5: n.c.		5: n.c.

5.3 Voltage supply / fuse

Observe the maximum current rating of the M12 connections ( → tech. data)

ATTENTION

No current limitation within the unit.

▷ If the M12 connectors are overloaded (overcurrent), damage to the unit or fire is possible.
▷ Each supply connection AS-i + / AUX + (AS-i operation) or + 24 V DC (US) / + 24 V DC (UA) (IO-Link operation) must be limited to the values of the technical data (current consumption) by external measures.
▶ Device protected.
