If both the input and the output wiring are
n
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 33.3 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
33.3 amps, the wire size for that line and its
neutral must be coordinated for 33.3 amps.
The wire size must not be sized for anything
lower than 33.3 amps.
Size of Wiring Downstream of the AC Output Breaker (50A
single-phase)
The wire size must be coordinated with the current
the wiring will carry. This current may be determined
by the 33.3-amp maximum inverter current, or by the
pass-through current, which is determined by the
overcurrent protection provided ahead of the
Freedom EX 4000.
EQUIPMENT DAMAGE
Make sure the wires are connected properly. The
AC wiring terminal blocks are split into input and
output sections.
Failure to follow these instructions can result in
equipment damage.
When making the AC input and AC output
connections, observe the correct color code for the
appropriate AC wire, as described inTable 5 below.

Black/Red/Brown
White/light blue
Green, green/yellow, or bare
copper
REVERSE LINE/NEUTRAL DAMAGE
Make sure the wires are connected properly.
Improper connections (connecting a line conductor
to a neutral conductor, for example) will cause a
hazardous line to exist and may cause the
Freedom EX 4000 to malfunction and may
permanently damage the
inverter/charger/converter. Damage caused by
miswiring the line and neutral is not covered by
your warranty.
Failure to follow these instructions will result in
death or serious injury.

Wiring Knockouts
When installing wires to the AC terminals, the AC
input and output holes are provided to
accommodate ½" trade-size bushings (supplied) or
optional strain relief devices. If larger cables and
strain relief clamps are needed, remove the ¾"
trade-size knockout rings.
EQUIPMENT DAMAGE
Install optional AC knockout plugs over knockout
holes when not used for wiring to prevent objects
and other material from entering the unit.
Failure to follow these instructions can result in
equipment damage.
