applications, flexible multiple-strand wire may be required.
Installation codes usually specify solid or stranded, overall size of
the conductors, and type and temperature rating of the insulation
around the wire. Cord must be of type S, SE, SEOO, SO, ST,
STO, SJ, SJE, SJEOO, SJT or SJTO.
AC breakers and fuses must be sized to adequately protect the
wiring that is installed on the input and output AC circuits of the
Freedom X 1200. All breakers and wiring must be sized and
connected in accordance with the electrical codes or regulations
applicable to your installation.
wiring sizes based on the U.S. National Electrical Code and the
Canadian Electrical Code. These examples are based on using a
two-conductor-plus-ground copper cable rated at 60
°
C, and
assuming an ambient temperature of up to 30
°
C. Ensure that your
breakers and fuses have suitable temperature ratings for your
wiring. Other codes and regulations may also be applicable to your
installation.

AC Output Neutral Bonding
The neutral conductor of the Freedom X 1200’s AC output circuit
(that is, AC Output Neutral) is automatically connected to the
safety ground during inverter operation. When AC utility power is
present this connection is not present, so that the utility neutral
(that is, AC Input Neutral) is only connected to utility ground at
your source. This conforms to the National Electrical Code
(NEC), which requires that separately derived AC sources (such
as inverters and generators) have their neutral conductors tied to
ground in the same way that the neutral conductor from the utility
is tied to ground in only one place. Check the regulations for your
specific application to ensure that the installation will comply with
the necessary requirements. In other words, the AC Input Neutral
ground bonding and Output Neutral ground bonding must be
isolated from each other.
AC Grounding
As per UL458 SA29.5, for all permanently connected marine
inverters: The Freedom X 1200 should be connected to a
grounded, metal, permanent wiring system. Also, make sure that
an AC ground wire is connected to the AC ground terminal on the
unit. Do not just connect the line and neutral wires.
All connections to the unit should comply with NFPA 1192 and all
local codes and ordinances.
