The AC wires inside the AC compartment are #16 AWG with a tem-
perature rating of 105° C. All AC connections should be made using
an approved connector for your application (e.g., split bolt, twist-on
wire connectors, etc.). Ensure the wire connectors used are rated for
the size and number of wires you are connecting.
After connecting the wires together, gently pull on the wires to ensure
they are securely held together. In a proper connection, no bare wire
should be exposed
.
Info: Per UL certifi cation, non-metallic sheathed cable
(i.e., Romex™) or an SO fl exible cord with listed strain
reliefs are allowed to be used to connect to the inverter;
conduit connections are not allowed.
After all AC wiring in the inverter is complete (and before reattach-
ing the AC access cover), ensure all connections are correct and
secure.
Table 3, Wire Color to AC Wire Connection
AC Wiring Connections
For all hardwired inverter models, the AC input and output wiring is
performed in the AC wiring compartment. This compartment is located
on the top panel (see Figure 2, Item 8). If installed, remove the two
Phillips screws on the cover to access the AC wiring compartment
and locate the inverter’s AC wiring. There is a label located in the AC
access compartment which gives information on which wires are used
for the AC input and output. You can also refer to Table 3 to match
the inverter’s AC wires to the appropriate AC wire connection.
AC Wire Size and Overcurrent Protection
The AC input and output wiring must be sized per the NEC and local
electrical safety code requirements
to ensure the wire’s ability to
safely handle the inverter’s
maximum load current. After determining
the proper AC wire sizes, the inverter’s AC input (unless you are using
a fl exible cord) and output wires are required to be protected against
overcurrent and have a means to disconnect the AC circuits.
