SECTION 1 | Safety Instructions
1.1 SAFETY SYMBOLS
The following safety symbols will be used in this manual to highlight safety
and information:
WARNING!
Indicates possibility of physical harm to the user in case of non-compliance.
!
CAUTION!
Indicates possibility of damage to the equipment in case of non-compliance.
i
INFO
Indicates useful supplemental information.
Please read these instructions before installing or operating the unit to prevent personal
injury or damage to the unit.
1.2 SAFETY INSTRUCTIONS - GENERAL
1.2.1 Installation and wiring compliance
• Installation and wiring must comply with the Local and National Electrical Codes and
must be done by a certied electrician.
1.2.2 Preventing electrical shock
• Always connect the grounding connection on the unit to the appropriate grounding
system.
• Disassembly / repair should be carried out by qualied personnel only.
• Disconnect all AC and DC side connections before working on any circuits associated
with the unit. Turning the ON/OFF switch on the unit to OFF position may not entirely
remove dangerous voltages.
• Be careful when touching bare terminals of capacitors. Capacitors may retain high le-
thal voltages even after the power has been removed. Discharge the capacitors before
working on the circuits.
1.2.3 Installation environment
• The inverter should be installed indoor only in a well ventilated, cool, dry
environment.
• Do not expose to moisture, rain, snow or liquids of any type.
• To reduce the risk of overheating and re, do not obstruct the suction and discharge
openings of the cooling fan.
• To ensure proper ventilation, do not install in a low clearance compartment.

1.2.4 Preventing re and explosion hazards
• Working with the unit may produce arcs or sparks. Thus, the unit should not be used
in areas where there are ammable materials or gases requiring ignition protected
equipment. These areas may include spaces containing gasoline-powered machinery,
fuel tanks, and battery compartments.
1.2.5 Precautions when working with batteries
• Batteries contain very corrosive diluted Sulphuric Acid as electrolyte. Precautions
should be taken to prevent contact with skin, eyes or clothing.
• Batteries generate Hydrogen and Oxygen during charging resulting in evolution of
explosive gas mixture. Care should be taken to ventilate the battery area and follow
the battery manufacturer’s recommendations.
• Never smoke or allow a spark or ame near the batteries.
• Use caution to reduce the risk of dropping a metal tool on the battery. It could spark
or short circuit the battery or other electrical parts and could cause an explosion.
• Remove metal items like rings, bracelets and watches when working with batteries.
The batteries can produce a short circuit current high enough to weld a ring or the
like to metal and thus, cause a severe burn.
• If you need to remove a battery, always remove the ground terminal from the battery
rst. Make sure that all the accessories are off so that you do not cause a spark.
1.3 SAFETY INSTRUCTIONS - INVERTER RELATED
1.3.1 Preventing Paralleling of the AC Output
The AC output of the unit should never be connected directly to an Electrical Breaker
Panel / Load Centre 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 re 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 inverter) should rst be fed to an Automatic / Manual
Selector Switch and the output of the Selector Switch should be connected to the Elec-
trical Breaker Panel / Load Center. Samlex America, Inc. Automatic Transter Switch model
No. STS-30 is recommended for this application.
!
CAUTION!
To prevent possibility of paralleling and severe damage to the unit, never use a
simple jumper cable with a male plug on both ends to connect the AC output
of the unit to a handy wall receptacle in the home / RV.

SECTION 1 | Safety Instructions
1.3.2 Preventing DC Input Over Voltage
It is to be ensured that the DC input voltage of this unit does not exceed 16.5 VDC to
prevent permanent damage to the unit. Please observe the following precautions:
• Ensure that the maximum charging voltage of the external battery charger / alterna-
tor / solar charge controller does not exceed 16.5 VDC.
• Do not connect this unit to a battery system with a voltage higher than the rated 12V
nominal battery input voltage of the unit.
1.3.3 Preventing Reverse Polarity on the Input Side
When making battery connections on the input side, make sure that the polarity of bat-
tery connections is correct (Connect the Positive of the battery to the Positive terminal
of the unit and the Negative of the battery to the Negative terminal of the unit). If the
input is connected in reverse polarity, DC fuse(s) inside the inverter will blow and may
also cause permanent damage to the inverter.
!
CAUTION!
Damage caused by reverse polarity is not covered by warranty.
1.3.4 Use of External Fuse in DC input Circuit
Use Class-T or equivalent fuse of appropriate capacity within 7" of the battery Positive ter-
minal. This fuse is required to protect DC input cable run from damage due to short circuit
along the length of the cable. Please read instructions under Section 8 - Installation.
