The u-remote station's main power supply is fed in via the
coupler. A power feed module must be connected if the cur-
rent demand of the series of output modules is too large.
Power-feed modules serve to refresh the current paths and
isolate the power supply. The maximum feed-in current in
the output current path via the 4-pole connector is 10 A. De-
tails required to calculate current demand and power supply
seesection4.5.
Power-feed modules are passive modules without eld bus
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!
