Wiring the system power supply and load current supply modules

Introduction
In the delivery state of the system power supply and load current supply modules, 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 supply and load current
supply modules use identical power connectors for the voltage connection.
The coding element prevents the insertion of a power connector into a different type of
power supply module / load current supply module.
Tools required
3 to 3.5 mm screwdriver
Wiring the supply voltage to the system power supply and load current supply modules

m):
To connect the supply voltage, follow these steps:
1. Swing the front cover of the module up until the front cover latches.
2. Press down the unlocking button of the power cable connector (Figure 1). Remove the
3. Loosen the screw on the front of the connector. This loosens the housing latch and the
4. Pry off the connector cover using a suitable tool (Figure 3).
