6.7
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. The
coding is effected by means of two coding elements - 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.
Tools required
3 to 3.5 mm screwdriver
