Installation
2.6.4
Connecting a Large Ground Wire
Marine installations require the ground wire to be the same size or one size smaller than the
negative cable. Use the following steps to allow a larger ground wire to be connected.
Locate the DC Equipment Ground Terminal
(see Figure 1-2, Item 7).
Locate and remove the AC Access Cover plate
(see Figure 1-3, Item 15) on the side of the
ME inverter.
Within the AC wiring area, locate the hex
nut on the backside of the DC ground termi-
nal. After locating the hex nut, use a 7/16”
wrench/nut driver to remove the hex nut,
bolt, lock washer and DC ground terminal,
and then remove them from the chassis.
Reverse the removed bolt, and place it back
in the chassis hole to attach a correctly sized
ground cable to the ME Series chassis, as
shown in Figure 2-20.
Place the washer and nut on the bolt, over
the ground cable, and securely tighten the
nut [from 4 to 5 ft lbf (5.4 to 6.8 N-m)].
Replace the AC Access Cover plate and se-
cure.

Notifi cation Requirements
A warning label as shown in Figure 2-21 is provided to inform all personnel that an inverter is
installed in your electrical system. Af
fi
x this label in a clearly visible location at the electrical panel
that is being powered by the inverter. This is because it might be falsely assumed that the panel is
no longer “hot” after the AC power has been shut off, when power may actually still be available
due to the inverter automatically powering the panel.
