Power Supply Connector

You use the power supply connector to connect a power supply module to your supply. When delivered, the power supply connector is plugged into the power supply module. There are two versions (AC and DC) of power supply connector. The two versions are coded, meaning an AC connector can only be plugged into an AC power supply module, and a DC connector can only be plugged into a DC power supply module.

1.Open the cover of the power supply module.

2.Detach the connector by levering it off with a suitable tool, for example, a screwdriver, at the opening provided (1).

3.Pull the connector forward and out of the power supply module (2).
