Cables

WARNING

Do not extend cables

The power cable of the module with power supply is designed with a length of 5 m and the optional power cables for modules with connector are designed with a length of up to 10 m to match the 16 A "B" circuit breaker of the power supply unit. Never extend the power cables, since correct tripping of the circuit breaker cannot be guaranteed with an extended power cable.

Extending the power cables can cause irreparable damage to the modules or result in electrocution causing serious injury or death.

Beckhoff cables have been tested with regard to the materials, shielding and connection method used. They ensure proper functioning and compliance with statutory regulations such as EMC and UL. The use of other cables may lead to unexpected interference and invalidate the warranty.

Beckhoff recommendation for correct application and assembly:

  • Wiring in accordance with applicable regulations and standards
  • Use the pre-assembled and shielded Beckhoff cables for power and EtherCAT connections

Laying

The following cables are integrated in the supply modules:

For modules with connectors, the following cables can be connected for "fixed installation":

For modules with connectors, the following cables can be connected for moving track sections:

The ZK7Axx-3031-xxxx cables require the following adapter:

Lay the cables so that they are protected against external damage. Make sure that the cables lie in a position where they are protected against moving machine parts and their acceleration forces.

Note the specified bending radii and bending cycles with different laying for the power cables and EtherCAT cables in the table:
