5.31 Power-feed Module for Output Current Path EP-7641
Power-feed Module for Output Current Path EP-7641
Power-feed modules are used to refresh the current paths and isolate the power supply. The RSTi-EP
station's main power supply is always fed in via the network adapter. A power-feed module EP-7641
must be connected if the current demand of the series of output modules is too large.
The maximum feed-in current in the output current path via the 4-pole connector is 10 A. Details
required to calculate current demand and power supply refer to the section, Current Demand and
Power Supply.
Power-feed modules are passive modules without fieldbus communication, therefore they are not
considered during configuration.
Note: A maximum of three passive modules (powerfeed module, potential distribution module,
empty slot module) may be installed in succession, however the next module to be installed
must be an active module.
In the case of a maximum power supply of >8 A and a maximum
temperature of > +55°C (131 °F), all four contacts must be connected with
1.5 mm² wiring.
