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.

Table 1 Tested GFCI Models

Manufacturer	Model Number

Hubbell	GFR5252WA
Leviton	8599-GY
Pass & Seymour	1594-W

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.
