SECTION 1 | Safety Instructions
• Disassembly / repair should be carried out by qualied 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.
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.
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.
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
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
