When laying the cables, also ensure that
● no more than one conductor pair is bundled and
● the 24 V cables are routed separately away from other cables and conductors that could
carry the operating current.
Using an external 24 V power supply
When using an external 24 V power supply, e.g. SITOP, you must use the 24 V terminal
adapter. The external power supply should be located very close to the load (max. cable length
30 m). Miniature circuit breakers with tripping characteristic D are recommended as
overcurrent protective devices for the cables and conductor bars. You must connect ground
potential M to the protective conductor system.

Example of an external 24 V power supply
Using the 24 V connector
● A 24 V connector must be plugged onto the 24 V busbar between the Line Module, Adapter
Module 600 and DC-link component.
● Attachment and removal are only permissible in a no-voltage state.
● A maximum of 5 unplugging and plugging cycles is permissible.
