Installing and Operating AN/DC and ANH-8/DC Systems

9.Connect an earth ground to either the leftmost terminal block or to the grounding stud, located between the power switch and terminal connectors (Figure 1-13).

If connecting to the grounding stud, use a #6 ring terminal.

Note: Use the same wire gauge (or greater) for the earth ground as that used for connection to the power source. That is, if connection to the power source uses #16 AWG cable, use #16 AWG cable for the ground. If connection to the power source uses #18 AWG cable, use #18 or #16 AWG cable for the ground.

10.Before qualified service personnel connect the AN/DC to the power source, verify that the power switch is OFF and that the AN/DC is properly grounded.

Danger: Once the AN/DC is connected to the power source, do not remove the input wires. You must disconnect from the power source before removing the AN/DC power input wires.
