7.7 Connecting system power supply and load current supply
Introduction
In the delivery condition of the system power supplies/load current supplies, power
connectors are inserted. The modules and the associated power connectors are coded. There
are two parts to the coding element. One coding element is located in the module, and the
other in the power connector. The system power supplies/load current supplies use identical
power connectors for the voltage connection.
The coding element prevents the insertion of a power connector into a different type of
system power supply/load current supply.
