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. Remove the inverter’s AC access cover plate

(see Figure 1-3, Item 15).

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

terminal. Use a 7/16” wrench/nut driver to

remove the hex nut, bolt, lock washer and

DC ground terminal.

4. Reverse the removed bolt, and place it back

in the chassis hole. Attach a correctly sized

ground cable with a ring terminal to the

ME’s chassis—as shown in Figure 2-19.

Note: Ring terminal must have a hole size ≥1/4”.

5. Place the washer and nut on the bolt—over

the ground cable—and then securely tighten

the nut [from 4 to 5 lbf-ft (5.4 to 6.8 N-m)].

Replace the AC access cover plate.

2.7 Inverter Notiﬁ cation Requirements

A warning label as shown in Figure 2-20 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.
