AC Output: The circuit breaker or fuse used must be
rated and approved for use on 120V AC branch circuits
for 120V models and for 230VAC branch circuits for
230V models. The wire size used between the Sine Wave
Inverter output and the breaker, and between the breaker
and your loads, must be sized to match the circuit
breaker’s rating, in accordance with the electrical codes
or regulations applicable to your installation. Refer to
Table 1 for sizing information.
Disconnect devices: Since circuit breakers can be turned
off and fuses can be removed from the circuit, either
type of device will also meet the requirement for a
disconnect device in each of the above circuits. Note
that the required disconnect device is not intended for
disconnection under load, it is only meant to be a way
to isolate the Sine Wave Inverter from the input and
output power sources.
2.4.2 Making AC Wiring Connections
Again, this section applies to those models configured
with an AC hardwire terminal strip. As mentioned
previously, your AC wiring must be sized to match the
current rating of the AC breakers you provide on the
input and output AC circuits in accordance with the
electrical codes or regulations applicable to your
installation. Table 1 is based on the U.S. National Electrical
Code (1999), the Canadian Electrical Code (1998), and
European wiring practices (for 230V models). There may
be other codes and regulations applicable to your
installation.
Note that there is no difference between the
recommendations for the 1000 and 1800 models. This is
because the bypass rating of these products is the same
(i.e. 15A for 1000 and 1800 and 10A for 1000i and
1800i).
Figure 3 may be a useful reference as it illustrates the
AC wiring connection terminals for Sine Wave Inverter
models that are AC hardwire configured.
AC Wiring should be connected in the following order:
1. AC INPUT (source)
2. AC OUTPUT (load)
To make AC wiring connections:
1. The AC wiring compartment is located on the right-
hand side of the Sine Wave Inverter when looking at
the front of the unit. Remove the AC wiring
compartment cover to gain access to the AC terminal
strip inside.
2. Remove the knockouts from the cover of the wiring
compartment to create holes for your cable clamps
(see Figure 3).
3. Run the three conductor AC INPUT (source) wiring
through a cable clamp and into the wiring
compartment, via the knockout on the right side of
the front panel. Connect the AC INPUT ground
wire first to the ground terminal (ground symbol
with circle around it), and then connect the AC
INPUT line and neutral wires to the corresponding
Sine Wave Inverter AC input terminals. Refer to
Table 2 for typical colour coding and terminal
identification.
4. In a similar manner, connect the AC OUTPUT (load)
wiring to the Sine Wave Inverter AC output terminals
(connect the output ground to the ground terminal
identified by the symbol with no circle around it).
Terminal to wiring connections should be done as
shown in Table 2.
5. After wiring, double check and review all connections
to make sure the wires are in the correct terminals
and the terminals are tight (the recommended torque
is 7.5 in-lbs., 9.8 Nm).

WARNING
Shock Hazard. Before proceeding further,
ensure that the Sine Wave Inverter is NOT
connected to any batteries, and that all
wiring is disconnected from any electrical
sources. Do not connect the output
terminals of the inverter to an incoming AC
source.
