INSTALLATION

GENERAL
Installation and wiring compliance
•
Installation and wiring must comply with the local and the national electrical codes and must
be done by a certified electrician
•
In building / residential applications, electrical codes do not allow permanent connection of
AC distribution wiring to the inverter’s AC output receptacles. The receptacles are intended
for temporary (as needed) connection of cord connected loads only.
Read details under “AC
Power Distribution and Grounding” on page 9.
•
The inverter does not have integral over current protection for the AC output side.
Protection should be provided by the installer
•
Over current protection of the cables from the battery to the inverter has to be provided by
the installer
•
The DC input positive and negative terminals are isolated from the chassis. Similarly, the
neutral pole of the AC receptacles / the neutral wire is not bonded to the chassis. System
grounding to suit the national / local electrical codes is to be undertaken by the installer.
Read details under“AC Power Distribution and
Grounding” on page 9.
Preventing electrical shock
•
Always connect the grounding connection on the inverter to the appropriate
grounding system.
Read details under“AC Power Distribution and
Grounding” on
page 9.
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 fire, do not obstruct the suction and
discharge openings of the cooling fans.
•
To ensure proper ventilation, do not install in a low clearance compartment
•
Working with the inverter may produce arcs or sparks. Thus, the inverter 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, battery compartments
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 horizontally
(the fan axis should always be horizontal i.e. the fans should
not be pointing up or down).
Cooling by forced air fan ventilation
The inverter produces heat when operating. The amount of heat produced is
proportional to the amount of power supplied by the inverter. A DC fan is used to
provide forced air cooling of this inverter. The fan is 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 unit is 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.
