Chapter 2 Cabling the CSS

Connecting the Power Cord

3.Using a flat-head screwdriver, loosen the captive screws on the three DC

connectors (labeled from left to right, –, +, and , respectively).

Warning Before installing a wire, ensure that the polarity of the DC connections is correct. Reversed polarity causes damage to the DC power supply and can create a dangerous shock hazard.

Do not consolidate the end of a conductor by soft soldering prior to installation.

4.Install the wires into the appropriate connector. Make sure that the non-insulated part of each wire is 9 mm (0.35 inches) in length.

Warning When installing the wires, always connect the ground wire first. When disconnecting the wires, always disconnect the ground wire last.

5.Tighten the captive screws to 5 to 7 inch-pounds (0.6 to 0.8 Nm) of torque to secure the wires in the connectors. Ensure that the wires are held firmly in place.

6.Install the wires to the DC power source.

For the proper power cable wiring between the CSS 11503 and DC power source, see Table 2-9.
