2 .5 .3 AC Term inal Block Connect ions

The inverter has a four-pole AC terminal block and one AC ground terminal to connect the inverter’s

AC input and output wiring. This terminal block allows either a service/distribution panel (main panel)

or a generator to be wired to the inverter’s input, and then to a dedicated panel (sub-panel) between

the inverter’s output wiring and the AC loads. To access and view the AC terminal block and ground

terminal, remove the two Phillips screws holding the AC access cover plate (see Figure 1-3, Item 15).

Each connection on the AC terminal block is rated to accept one 2.1 to 13.3 mm

(#14 to #6 AWG) CU

stranded wire, or two 3.3 mm

(#12 AWG) CU stranded wires. Each connection uses a M3.5 slotted

head screw, and the maximum tightening torque is 1.8 N-m (16 lbf-in).

I nfo: For marine installations and to comply with standard safety requirements, the

four-pole AC terminal is provided with a stainless steel wire protector to prevent wire

damage from the set-screw.

I nfo: The inverter’s NEUT IN and NEUT OUT terminals are electrically isolated from

each other while inverting. This is related to the neutral-ground bonding requirement

and helps to prevent ground-loops (see Section 2.6.5 for more information). If the

installation requires the input and output neutrals to be connected together, the

inverter’s neutral-to-ground connection must be disconnected (see Section 2.6.6).

The AC ground terminal can accept one 2.1 to 13.3 mm

(#14 to #6 AWG) CU stranded wire. It

uses a slotted head screw and has a recommended maximum tightening torque of 5.1 N-m(45 in

lbf). For multiple ground wires, use a pressure or mechanical connector to attach the single wire

from the AC ground terminal to the input and output ground connections.
