Mounting Position of the inverter
The inverter may be mounted horizontally on the top of a horizontal surface or under
a horizontal surface. The inverter may be mounted on a vertical surface only horizon-
tally (the fan axis should always be horizontal i.e. the fan should not be pointing up or
down).
cooling by Forced Air Fan Ventilation
The inverters produce heat when operating. The amount of heat produced is propor-
tional to the amount of power supplied by the inverter. dc fans are used to provide
forced air cooling of these inverters. The fans are thermostatically controlled and will
be switched on only if the temperature of certain hot spot inside the inverter rises
above a certain temperature. At lower loads and / or at lower ambient temperatures,
the fan may not switch on at all. This is normal. The units are protected against over-
temperature due to failure of the fan / inadequate heat transfer. The Ac output will be
shut-down if the hot spot inside the inverter reaches a certain higher temperature. The
unit will automatically reset once it cools down.
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 flame 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 bat-
tery first. Make sure that all the accessories are off so that you do not cause a spark.
Dc SiDe connectionS
The dc input power to the inverter is derived from deep cycle batteries of the
required capacity. read under "Section 6”on page 15 for details on sizing and charging
of batteries.
Preventing input over Voltage
It is to be ensured that the input voltage of the inverter does not exceed 16.5 Vdc to
prevent permanent damage to the inverter. Please observe the following precautions:
- Ensure that the maximum charging voltage of the battery charger / alternator / solar
charge controller is below 16.5 Vdc.
