Planning Preparations
This guide for use by qualified personnel only.
Size of AC Output Wiring Wire size must be coordinated
with the current the wiring will carry. This current may be
determined by the 25-amp (
$3
) and 20-amp (
$3
) maximum inverter current, or by the bypass current,
which is determined by the overcurrent protection provided
ahead of the
$XWR3RZHU
.
Some conditions for
$XWR3RZHU
• If the input wiring is split-phase, the output wiring must
be sized to coordinate with the breakers used on the input.
Refer to your applicable installation codes.
• If the input wiring is dual-input and the output wiring is
single-input, the following rules apply: If the input
breaker on L1 is greater than 25 amps, the wire size must
be coordinated for that amperage. If the input breaker on
L1 is less than 25 amps, the wire size must be coordinated
for 25 amps. The wire size must not be sized for anything
lower than 25 amps.
• If both the input and the output wiring are dual-input, the
output wiring for each line (L1 and L2) must be
calculated separately, following these rules: If the input
breaker on the specific line is greater than 25 amps, the
wire size for that line and its neutral must be coordinated
for that amperage. If the input breaker on the specific line
is less than 25 amps, the wire size for that line and its
neutral must be coordinated for 25 amps. The wire size
must not be sized for anything lower than 25 amps.
Size of Wiring Downstream of the AC Output Breaker
The wiring used between the AC output breaker and your
loads must be sized to match the output breaker.
AC Output Neutral Bonding
The AC source must have its neutral conductor bonded to
ground.
Bonding system The
$XWR3RZHU
provides a system that
automatically connects the neutral conductor of the inverter’s
AC output circuit to safety ground (“bonding” it) while the
inverter/charger is inverting, and disconnects it (“unbonding”
it) when the inverter/charger is connected to external AC
power. This system is designed to conform to installation
codes that require AC sources such as inverters and
generators to have their neutral conductors tied to ground at
the source of power in the same way that the neutral
conductor from the utility is tied to ground. These same codes
specify that the neutral can only be connected to ground in
one place at any one time.
