8 Freedom SW 2000 Installation Guide
Planning the Installation
AC Output Protection
The breaker between the Freedom SW 2000 AC output and the AC loads
must be rated to protect the AC output wire size used. If the AC output
wiring is based on the full 30A pass-through current rating, then a 30A
output breaker is acceptable. If the AC output wiring is smaller, then the
breaker size will have to be smaller as well, in accordance with applicable
electrical installation codes.
GFCI Requirements
A GFCI (ground fault circuit interrupter) is a device that de-energizes a
circuit when a current to ground exceeds a specified value that is less than
that required to open the circuit breaker. GFCIs are intended to protect
people from electric shocks and are usually required in wet or damp
locations.
Installation in recreational vehicles requires GFCI protection of certain
branch circuits. Consult all applicable codes.
Tested GFCIs
Compliance with UL standards requires that Xantrex test and recommend
specific GFCIs for use on the output of the inverter. Table 1 lists models
that have been tested and will function properly when connected to the AC
output of the Freedom SW 2000.
Disconnect Devices
Each system requires a method of disconnecting the AC circuits. If the
over-current protection device is a circuit breaker, it will also serve as the
disconnect. If fuses are used, separate AC disconnect switches will be
needed between the source and the fuses.
Distribution Panels
Some systems incorporate distribution panels both ahead of the inverter/
charger (the AC source panel) and between the inverter/charger and the
loads (the AC load panel). The AC source panel includes a main circuit
breaker, which serves as over-current protection for the panel. Additional
circuit breakers serve individual circuits, one of which serves the inverter/
charger.
