Chapter 3 Power Supply and Fan Module Installation

Installing a DC-Power Supply

Wiring the DC-Input Power Source

To wire the DC-power-supply module to a DC-input power source, follow these steps.

Step 1 Using a wire-stripping tool, strip each of the four wires coming from the DC-input power source to the

appropriate length for either the round eyelet or the fork-type terminals.

Step 2 Using a Panduit crimping tool, crimp the terminals to the 16-gauge DC-power input wires.

Step 3 Connect the DC-input power terminals to the terminal blocks as shown in Figure 3-10 or Figure 3-11.

Make sure to match the polarity (negative to negative, positive to positive) when connecting the wires to

the terminal blocks.
