Single Power Source:
The DC power module shown below is located at the rear of the docking station. Internally the
output of the DC power module connects to a panel-mounted connector via a cable assembly.
This connector mates with a DC-to-DC 12 V DC power supply connector on the tray.
DC Connections:
Complete the following steps to connect a single power source to the DC power
module.
1. Ensure both circuit breakers on the DC power module are set to OFF (O).
2. Turn power OFF at power source.
3. Route the RET and -48V wires from the external power source to the DC power
module plug. Secure the wires to the plug with screws. NOTE: The power
module plugs are in a small plastic bag included in your shipment.
4. Insert the plug into the DC power module and secure with screws.
5. Turn power ON at power source.
6. Press the required circuit breaker on DC power module to ON (I).
Warnings/Cautions
WARNING:
 Failure to turn power OFF at the power source may result in electrical shock.
 Ensure that the wires are pushed into the plug far enough, so that none of the
copper is visible.
 The DC power module plugs are polarity sensitive. The unit will not operate if the
plugs are not wired correctly. See wiring diagram below.
