Supply voltages

WARNING

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 supply provides safe electrical isolation and limitation of the voltage without a connection to the protective conductor, a PELV supply also requires a safe connection to the protective conductor.

CAUTION

Observe the UL requirements

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

The EtherCAT Box is supplied with two supply voltages. The supply voltages are electrically isolated in the EtherCAT Box.

Redirection of the supply voltages

The IN and OUT power connections are bridged in the module (not IP204x-Bxxx and IE204x). The supply voltages US and UP can thus easily be transferred from EtherCAT Box to EtherCAT Box.

Notice

Pay attention to the maximum permissible current!

Pay attention also for the redirection of the supply voltages US and UP, the maximum permissible current for M8 connectors of 4 A must not be exceeded!
