2.0 Installation

The AC wires inside the AC compartment are 1.31 mm² (#16 AWG)
with a temperature 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
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 of the AC wiring in the inverter is complete (and before reat-
taching the AC access cover), ensure all connections are correct and
secure.

which wires are used for AC input and output. You can also refer
to Table 2-3 to match the inverter’s AC wires to the appropriate AC
wire connection.

2.8.3 AC Wire Size and Overcurrent Protection

The AC input and output wiring must be sized per the IEC and local
electrical safety code requirements to ensure the wire’s ability to
safely handle the inverter’s maximum load current. After determin-
ing 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.

All inverter AC input and output wiring is required to be protected
by an overcurrent protection device. Overcurrent protection must be
provided by fuses or circuit-breakers, and must be properly sized and
rated for the wire they are protecting and the appliances being powered.
