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 12 V) 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.
Failure to follow these instructions will result in death or serious
injury.

This guide for use by qualified personnel only.
NOTES:
 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.
 This inverter/charger contains components which tend to produce arcs
or sparks.
 Locations include any space containing gasoline-powered machinery,
fuel tanks, as well as joints, fittings, or other connections between
components of the fuel system.
 $XWR3RZHUDQG inverter/charger products are designed for
deep cyclelead-acid batteries only. Charging lithium-ion batteries are
currentlynot supported and doing so is an explosion hazard.
Lithium-ion battery cells are individually monitored for voltage and
temperature. The $XWR3RZHUdoes not support this
individual cellmonitoring on lithium-ion batteries.
Precautions When Working With Batteries
NOTES:
 Mount and place the Inverter/Charger unit away frombatteries in a
well ventilated compartment.
 Always have someone within range of your voice or close enough to
come to your aid when you work near a lead-acid battery.
 Always have plenty of fresh water and soap nearby in case battery acid
contacts skin, clothing, or eyes.
 If battery acid contacts skin or clothing, wash immediately with soap
and water. If acid enters your eye, immediately flood it with running
cold water for at least twenty minutes and get medical attention
immediately.
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.

Planning the Installation
This section provides information to help you plan for a basic
installation of the $XWR3RZHU,QYHUWHU&KDUJHUDQG
.
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 1.
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 10 feet
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 Auto Power
To choose an appropriate location for mounting the inverter/
charger, see “Step 1: Choosing a Location for the Inverter/
Charger” on page 2.
