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.
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 fan.
- 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 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 proportional 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 tempera-
ture.
At lower loads and / or at lower ambient temperatures, the fan may not switch on at all.
The units are protected against over-temperature due to failure of the fan /
This is normal.
inadequate heat transfer. The AC output will be shut-down if the hot spot inside the
inverter reaches a certain higher temperature.
