AC Terminal Block Connections
The inverter has a four-pole AC terminal block and one AC ground terminal to connect the inverter’s
AC input and output wiring. 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 #14 to #6 AWG (2.1 to 13.3 mm
2
)
CU stranded wire, or two #12 AWG (3.3 mm
2
) CU stranded wires. The connection uses a M3.5 slotted
head screw, and the maximum tightening torque is 16 in lbf (1.8 N-m).
Info
: For alternative energy 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.
Info
: The inverter’s NEUT IN and NEUT OUT terminals are connected together
internally.
The AC ground terminal can accept one #14 to #6 AWG (2.1 to 13 mm
2
) CU stranded wire. It uses
a slotted head screw and has a recommended maximum tightening torque of 45 in lbf (5.1 N-m).
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.
