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. Make certain the lead color coding you choose for the
DC-input power supply matches lead color coding used at the DC power source.
Warning When you install the unit, the ground connection must always be made first and disconnected last. Statement 42
Caution The DC return connection to this system is to remain isolated from the system frame and chassis (DC-I).

Step 4 Insert the stripped end of the ground lead (1) all the way into the ground lead receptacle on the DC-input power supply,
and tighten the receptacle screw using a 3/16-inch flat-blade screwdriver.
Step 5 Insert the stripped end of the +V lead all the way into the +V lead receptacle and tighten the receptacle screw using the
same 3/16-inch flat-blade screwdriver. Repeat this step for the –V lead.
