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.
Figure 1-13. Attaching AN/DC Power and Ground Cables
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.
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.
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.
