Installation
2.6.4 Connecting a Large DC Ground Wire
Marine installations require the DC 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.
WARNING: Fire and Shock Hazard – disconnect all AC and DC sources before working
in the AC wiring compartment.
1. Locate and remove the AC Access Cover plate
(see Figure 1-3, Item 15) on the side of the
ME Series inverter.
2. Locate the DC Equipment Ground Terminal
(see Figure 1-2, Item 7).
3. 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.
4. Reverse the removed bolt, and place it back
in the chassis hole to attach a correctly sized
ground cable with a ring terminal to the ME
Series chassis, as shown in Figure 2-18.
Note: Ring terminal must have a hole size ≥1/4”.
5. 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)]. Re-
place the AC Access Cover plate and secure.

2.7 Inverter Notifi cation Requirements
A warning label as shown in Figure 2-19 is provided to inform all personnel that an inverter is
installed in your electrical system. Affi 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.
This electrical system is equipped with an Automatic
Generator Starting (AGS) device and/or an inverter.
Disconnect all AC and DC power to the AGS and/or
inverter before performing any service to the electrical
system. Failure to do so can result in shock causing
serious injury or death.
