Power connection
WARNING
Safety First! Calculate the maximum possible current in each power wire and common wire. Ob-
serve all electrical codes dictating the maximum current allowable for each wire size. If the current
goes above the maximum ratings, the wiring could overheat, causing serious damage to your
equipment.
The fibre-optic signal cables for the FreeCon Active PROFINET-POF-Repeater can be routed in a single ca-
bling channel together with the power cabling. The cabling should be implemented in accordance with the
PROFINET Installation Guideline for Cabling and Assembly.
We recommend labelling the wiring to all devices.
Use Weidmüller’s IE-PS-VAPM-24V power plug (order number 1068910000) to connect to the FreeCon Ac-
tive PROFINET-POF-Repeater.

Power is supplied to the FreeCon Active PROFINET-POF-Repeater only via US1. US2 is forwarded through
the device and only used for actuator supply.
