Power-feed modules are used to refresh the current paths
and isolate the power supply. The u-remote station‘s main
power supply is always fed in via the coupler. A power-feed
module UR20-PF-I must be connected if the current demand
of the series of input modules is too large.
The maximum feed-in current in the input current path via
the 4-pole connector is 10 A. Details required to calculate
current demand and power supply seesection4.5.
Power-feed modules are passive modules without eldbus
communication, therefore they are not considered during
conguration.
A maximum of three passive modules (power-
feed module, potential distribution module,
empty slot module) may be installed in succes-
sion, however the next module to be installed
must be an active module!

ATTENTION
Risk of material damage!
In the case of a maximum power supply of >8 A and a
maximum temperature of > +55 °C, all four contacts must
be connected with 1.5mm² wiring!
