Note
The power-supply module 1 connection is labeled PSU1, and the power-supply module 2 connection is
labeled PSU2. Make sure that you connect the wires to the correct terminal screws.
Step 3
Use twisted-pair copper wire (12- to 18-AWG) to connect from the power-input terminal to the power source.
Step 4
Strip each of the two wires to 0.25 inch (6.3 mm) ± 0.02 inch (0.5 mm).
Note
Do not strip more than 0.27 inch (6.8 mm) of insulation from the wire. Stripping more than the recommended
amount of wire can leave exposed wire from the connector after installation.
