Basic Installation Procedures
This
section for use by
qualified per
sonnel
only.
AC wiring must be sized appropriately to carry full load current on
the input and output AC circuits in accordance with the electrical
codes or regulations applicable to your installation. Table 4 is based
on the U.S. National Electrical Code and the Canadian Electrical
Code, assuming two-conductor-plus-ground cable, using 75 °C
wiring, at an ambient temperature of 30 °C. Other codes and
regulations may be applicable to your installation.

. The unit comes with either screw or spring clamp-type
terminals where individual wires can be attached securely.
When making the AC input and AC output connections, observe the

NOTICE
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 damage the unit and/or equipment.
NOTICE
REVERSE POLARITY DAMAGE
Make sure the wires are connected properly. Improper connections
(connecting a line conductor to a neutral conductor, for example) will
cause the Freedom X to malfunction and may permanently damage the
inverter. Damage caused by a reverse polarity connection is not covered
by your warranty.
Failure to follow these instructions can damage the unit and/or equipment.
