• Do not expose the Freedom SW 230V to rain, snow, spray, or bilge
water. This inverter/charger is designed for marine applications only
when additional drip protection is installed in certain orientations.
See the installation guide for information.
• Do not operate the inverter/charger if it has received a sharp blow,
been dropped, has cracks or openings in the enclosure including if
the AC terminal cover has been lost, damaged, or will not close, or
otherwise damaged in any other way.
• Do not disassemble the inverter/charger. Internal capacitors remain
charged after all power is disconnected.
• Disconnect both AC and DC power from the inverter/charger before
attempting any maintenance or cleaning or working on any circuits
connected to the inverter/charger. The INVERTER ENABLE button
on the front panel does not function like a power switch that
energizes or de-energizes the unit arbitrarily. When AC and DC power
sources are connected and present, the unit is always energized.
• Do not operate the inverter/charger with damaged or substandard
wiring. Make sure that all wiring is in good condition and is not
undersized.
Failure to follow these instructions will result in death or serious injury.
FIRE AND BURN HAZARD
• Do not cover or obstruct the air intake vent openings and/or install in
a zero-clearance compartment.
• Do not use transformerless battery chargers in conjunction with the
inverter/charger due to overheating.
Failure to follow these instructions will result in death or serious injury.
EXPLOSION HAZARD
• Charge only properly rated (such as two 12 V in series for a 24 V
battery bank) lead-acid (GEL, AGM, Flooded, or lead-calcium)
rechargeable batteries because other battery types may explode.
• Do not work in the vicinity of lead-acid batteries. Batteries generate
explosive gases during normal operation. See note #1.
• Do not install and/or operate in compartments containing flammable
materials or in locations that require ignition-protected equipment.
See notes #2 and #3.
• When using Lithium-Ion batteries, ensure that the battery pack being
used includes a certified Battery Management System (BMS) with
safety controls.
Failure to follow these instructions will result in death or serious injury.
iv Freedom SW 230V Installation Guide
NOTES:
1. Follow these instructions and those published by the battery
manufacturer and the manufacturer of any equipment you intend to use
in the vicinity of the battery. Review cautionary markings on these
products and on the engine.
2. This inverter/charger contains components which tend to produce arcs
or sparks.
3. Locations include any space containing gasoline-powered machinery,
fuel tanks, as well as joints, fittings, or other connections between
components of the fuel system.
PHYSICAL INJURY HAZARD
This Freedom SW 230V is not intended for use by persons (including
children) with reduced physical, sensory, or mental capabilities or lack of
experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for
their safety. Children should be supervised to ensure that they do not play
with the appliance.
Failure to follow these instructions can result in minor or moderate injury.
Precautions When Working With Batteries
BURN FROM HIGH SHORT-CIRCUIT CURRENT, FIRE AND
EXPLOSION FROM VENTED GASES HAZARDS
• Always wear proper, non-absorbent gloves, complete eye protection,
and clothing protection. Avoid touching your eyes and wiping your
forehead while working near batteries. See note #4.
• Remove all personal metal items, like rings, bracelets, and watches
when working with batteries. See notes #5 and #6 below.
• Never smoke or allow a spark or flame near the engine or batteries.
• Never charge a frozen battery.
• Always remove the negative terminal from the battery first for

Planning the Installation
This section provides information to help you plan for a basic
installation of the Freedom SW 230V.
As your system configuration is determined, record the details
in “Information About Your System” in the Freedom SW
230V Sine Wave Inverter/Charger Owner’s Guide.
Two Key Performance Factors
Two key factors in particular will have a major impact on
system performance.
Size and Length of DC Cables
To select the appropriate size and length of DC cables, see
“DC Cabling” on page 14.
The DC cables should be as short as possible and large
enough to handle the required current, in accordance with the
electrical codes or regulations applicable to your installation.
If there are long battery cables which are in excess of 3 meters
each and not of sufficient size, the voltage drop across the
cables will have a negative impact on overall system
performance.
Mounting Location of the Freedom SW 230V
To choose an appropriate location for mounting the inverter/
charger, see “Step 1: Choosing a Location for the Inverter/
Charger” on page 19.

AC Components
NOTE: Unless otherwise referenced specifically by product
name, the components refer to all models of Freedom SW
inverter/chargers.
AC Input
AC input can be supplied from a single-phase 230-volt 50-Hz
AC source such as the utility grid (power company), a
generator, or the output of a transfer switch.
AC Output
The output voltage on Freedom SW inverter/chargers is
230 volts AC. The Freedom SW 2524-230 and Freedom SW
3524-230 models have a Single Input and Single Output line
(SI-SO) configuration.
AC Loads
The Freedom SW 230V is intended to power loads consisting
of 230 volts/50 Hz AC appliances.
In Invert mode, the Freedom SW 230V provides 230 volts/
50 Hz AC to loads connected to Line out. In AC Bypass
mode, the source connected to the AC input is passed through
to the load. Only 230 volts/50 Hz AC appliances can be
connected to the Freedom SW 230V output.
AC Disconnect and Over-Current Protection
Device
To meet mobile electrical code requirements, and to protect
system wiring, the AC inputs and outputs of the inverter/
charger must be provided with overcurrent protection on both
the AC input and output. This protection may be a circuit
breaker or a fuse with a disconnect device (for simplicity the
following refers to breakers). Refer to your applicable
installation codes and the following requirements:
10 Freedom SW 230V Installation Guide
AC Input Protection
Planning Preparations
GFCI Requirements
The breaker protecting the AC input of the Freedom SW
230V must be approved for use on 230 volts AC branch
circuit. The breaker must be rated no more than 30 amps
maximum.
AC Output Protection
The breaker between the Freedom SW 230V 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 30-amp
pass-through rating, then a 30-amp 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.
A GFCI (ground fault circuit interrupter) is a device that deenergizes 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 may require GFCI
protection of certain branch circuits. Consult all applicable
codes.
Disconnect Devices
Each system requires a method of disconnecting the AC
circuits. If the overcurrent 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.
This guide for use by qualified installers only.
975-0697-01-01 11
Planning Preparations
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
overcurrent protection for the panel. Additional circuit
breakers serve individual circuits, one of which serves the
inverter/charger.
AC Wiring
Definition AC wiring includes input wiring (all the wires
and connectors between the AC source and the inverter/
charger input) and output wiring (all the wires between the
inverter/charger and the AC load panels, circuit breakers, and
loads).
Type The type of wiring required varies according to the
electrical codes or regulations applicable to your installation.
For RV applications, this may be solid wire in multiconductor cables, but stranded wire is required if single
conductors are used. All wiring must be rated 75 °C or higher.
Size of AC Input Wiring Wire size must be coordinated
with the overcurrent protection provided ahead of the wire
involved, in accordance with the electrical codes or
regulations applicable to your installation. Therefore, the
wiring used between the AC input circuit breaker and the
inverter/charger input must be sized to match the input
breaker rating.
