Step 1 Make certain that the chassis ground is connected before you begin installing the DC power supply.

Step 2 Locate the ground stud on the DC power supply for the GND connection which must be installed first and replace the ground stud components in the following order:

b.Washer

c.Grounding lug with wire

d.Kepnut screw

Step 3 Tighten the Kepnut screw to complete the installation. Figure 11 shows the installed DC power supply ground stud. Step 4 Ground the other end of the grounding wires to an appropriate grounding point at your site.

Step 5 Repeat Steps 2 through Step 4 on the second DC power supply.

Wiring the DC-Input Power Source

Note The color coding of the DC-input power supply leads depends on the color coding of the DC power source at your site. Typically, green or green/yellow is used for ground (GND) on the power supply. Negative –48V black is on negative (–) terminal and red is used for RTN on the positive (+) terminal. Make certain the lead color coding you choose for the DC-input power supply matches lead color coding used at the DC power source.

Step 1 Make sure the power switch circuit breaker is in the Off position.

Step 2 Locate and remove the plastic cover from the terminal block.
