Connecting the load current supply

Introduction
In the delivery condition of the 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 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 load
current supply.
Tools required
3 to 3.5 mm screwdriver

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
power cable connector from the front of the module.
3. Loosen the screw on the front of the connector. This loosens the housing latch and the
cable relief. With a tightened screw the connector's cover can't be removed (Figure 2).
