Input and forwarding

Power supply from SELV/PELV power supply unit!

SELV/PELV circuits (Safety Extra Low Voltage, Protective Extra Low Voltage) according to IEC 61010-2-201 must be used to supply this device.

Notes:

• SELV/PELV circuits may give rise to further requirements from standards such as IEC 60204-1 et al, for example with regard to cable spacing and insulation.
• A SELV (Safety Extra Low Voltage) supply provides safe electrical isolation and limitation of the voltage without a connection to the protective conductor,
  a PELV (Protective Extra Low Voltage) supply also requires a safe connection to the protective conductor.

Observe the UL requirements

• When operating under UL conditions, observe the warnings in the chapter UL Requirements.

Brake chopper required

Overvoltage peaks can occur on the supply voltage U_P which can destroy the device.

The overvoltage peaks occur during braking operations of the motor or by manually moving objects on the roller conveyor.

• Use a brake chopper to dissipate overvoltages.
  E.g. EP9576-1032 or EL9576.

Note the maximum current

When forwarding the supply voltages U_S and U_P, make sure that the current of 28 A at 45 °C permitted for the connectors is not exceeded:

U_P is not protected against polarity reversal

Defect possible through polarity reversal.

• Make sure that the supply voltage U_P is connected correctly.
