Installation
2.3.3 Recommended Ground Fault Circuit Interruption (GFCI) Breakers
In compliance with UL standards, Sensata has tested some GFCIs to ensure they function properly
when connected to the inverter’s AC output. See WARNING below.
WARNING:
Risk of electric shock. Use only the following GFCIs [receptacle(s) or circuit
breaker(s)]: Leviton #8899-A, N7899, GFNT1 and GNNT2. Other types may fail to
operate properly when connected to this inverter.
2.3.4 AC Input and Output Wiring Connections
The MS-PAE Series inverter/charger has a six-connection AC terminal block and two AC ground
terminals that are used to connect the inverter’s AC input/output wiring. To access the AC terminal
block and the ground terminals, remove the two Phillips screws that hold the AC access cover
plate to the left side of the inverter (see Figure 1-3, Item 15).
Each connection on the AC terminal block is rated for 221°F (105°C) and can accept a #18 to #4
AWG (0.82 to 21.1 mm
2
) CU solid/stranded wire. Each connection uses a set screw with slot-head,
and the recommended tightening torque is 16 in lbf (1.8 Nm).
Each AC ground terminal can accept one #14 to #6 AWG (2.1 to 13.3 mm
2
) stranded wire.
Recommended tightening torque is 45 in lbf (5.1 Nm).
Info:
The two neutral terminals are common to each other and can be used in any
combination or order. In a residential application, it is often easier to connect only one
AC neutral wire to the inverter and make the other neutral connections at a central
point, such as in the AC electrical panel.
