• Duringoperation,thesurfaceoftheunitmaybecomehot.The
unit should be installed so it is not likely to come into contact with
people.
Preventing fire and explosion hazards
• Workingwiththeunitmayproducearcsorsparks.Thus,theunit
should not be used in areas where there are inflammable materials
or gases requiring ignition protected equipment. These areas may
include spaces containing gasoline-powered machinery, fuel tanks,
and battery compartments.
Precautions when working with batteries.
• BatteriescontainverycorrosivedilutedSulphuricAcidaselectrolyte.
Precautions should be taken to prevent contact with skin, eyes or
clothing.
• BatteriesgenerateHydrogenandOxygenduringchargingresulting
in evolution of explosive gas mixture. Care should be taken to
ventilate the battery area and follow the battery manufacturer’s
recommendations.

parts and could cause an explosion.
• Removemetalitemslikerings,braceletsandwatcheswhenworking
with batteries. Batteries can produce a short circuit current high
enough to weld a ring or the like to metal and thus, cause a severe
burn.
• Ifyouneedtoremoveabattery,alwaysremovethegroundterminal
from the battery first. Make sure that all the accessories are off so
that you do not cause a spark.

Preventing Paralleling of the aC Output
The AC output of the unit should never be connected directly to an
Electrical Breaker Panel / Load Center which is also fed from the utility
power / generator.
Such a direct connection may result in parallel operation of the different
power sources and AC power from the utility / generator will be fed back
into the unit which will instantly damage the output section of the unit
and may also pose a fire and safety hazard.
If an Electrical Breaker Panel / Load Center is fed from this unit and this
panel is also required to be fed from additional alternate AC sources,
the AC power from all the AC sources like the utility / generator / this
unit should first be fed to an Automatic / Manual Selector Switch and
the output of the Selector Switch should be connected to the Electrical
Breaker Panel / Load Center.
!
CAUTIon!
To prevent possibility of paralleling and severe
damage to the unit, never use a simple jumper cable
to connect the AC output of the unit to a handy wall
receptacle in the home / RV.
ATTENTION!
Afin de d'éviter la possibilité que l'appareil se met en
parallèle ou devient fortement endommagé, utilisez
pas un câble de raccordement pour lier la sortie CA
de l'appareil à un réceptacle du murcommode dans
la maison/VR.
Connecting to Multi-Wire branch Circuits
Do not directly connect the Hot / Line output of this unit simultaneously
to the two Hot Legs L1 and L2 of the 120 / 240 vAC Split Phase Electrical
Breaker Panel / Load Center where Multi-Wire (common Neutral) Branch
Circuit Wiring method is used for distribution of AC power. This may lead
to overloading / overheating of the Neutral conductor of the distribution
wiring system and is a risk of fire.
A suitable external transformer with a Split Phase output (Isolated
or Auto-Transformer) of suitable power rating (25% more than the
Apparent Power (vA) rating of this unit) with Primary of 120 vAC and
Secondary of 120 / 240 vAC (Two 120 vAC Split Phases 180 degrees
apart) should be used. The Hot and Neutral of the 120 vAC output of
this unit should be fed to the Primary of this external transformer and
the 2 Hot outputs (120v AC Split Phases) and the Neutral from the
Secondary of this external transformer should be connected to the two
Hot Legs L1 and L2 of the 120 / 240 vAC Electrical Breaker Panel /
Load Center.
Please read details under white Paper titled “120 / 240 VaC
single split Phase system and Multi-wire Branch Circuits” that is
available online at www.samlexamerica.com (Home > support >
white Papers).
Preventing Input over-Voltage
It is to be ensured that the DC input voltage of this unit is ≤ 16 vDC
for the 12v battery version and ≤ 32 vDC for the 24v battery version
