Basic Installation Procedures
This guide for use by qualified personnel only.
DC Disconnects and Over-Current Devices
The DC circuit from the battery to the Freedom HF must be
equipped with a disconnect and over-current device. This usually
consists of a circuit breaker, a “fused-disconnect,” or a separate fuse
and DC disconnect. Do not confuse AC circuit breakers with DC
circuit breakers. They are not interchangeable. The rating of the fuse
or breaker must be matched to the size of cables used in accordance
with the applicable installation codes. The breaker or disconnect
and fuse should be located as close as possible to the battery, in the
positive cable. Applicable codes may limit how far the protection
can be from the battery.
Batteries
The Freedom HF uses 12-volt battery banks. Every Freedom HF
system requires a deep-cycle battery or group of batteries that
provide the DC current that the Freedom HF converts to AC.
Ground Fault Circuit Interrupters (GFCIs)
A GFCI is a device that de-energizes a circuit when a current to
ground exceeds a specified value that is less than that required to
blow the circuit breaker. GFCIs are intended to protect people from
electric shocks and are usually required in wet or damp locations.
Installations in marine and recreational vehicles require GFCI
protection of branch circuits connected to the AC output of the
Freedom HF.
The modified sine wave output of the Freedom HF is not equivalent
to the waveform provided by electric utilities, and compliance with
UL and CSA standards requires that the manufacturer test and
recommend specific GFCIs that will work correctly with the
Freedom HF.
