installation
warnInG!
1. before commencing installation, please read the safety instructions explained in Section 1
titled “Important Safety Instructions”.
2. It is recommended that the installation should be undertaken by a qualified, licensed /
certified electrician.
3. Various recommendations made in this manual on installation will be superseded by
the National / Local electrical Codes related to the location of the unit and the specific
application.
4.1 LocAtIon oF InStALLAtIon
Please ensure that the following requirements are met:
Working environment: Indoor use.
cool: Heat is the worst enemy of electronic equipment. Hence, please ensure that the unit is installed in a
cool area that is also protected against heating effects of direct exposure to the sun or to the heat gener-
ated by other adjacent heat generating devices.
Well ventilated: The unit is cooled by convection and by forced air-cooling by 2-speed, load controlled fan(s)
(9 in figs 3.1.2 & 3.2.2). SSW-350 and 600 1 fan and SSW-1000, 1500 and 2000 have 2 fans. The fan(s) will run
as soon as the unit is switched oN – at slow speed from no load/to loads up to 10% of the power rating of
the inverter and at full speed thereafter. The fan(s) draws cool air from air intake openings in the front (9(b)
in figs 3.1.1 and 3.2.1) and discharges hot air through the exhaust openings next to the fan (9(a) in figs 3.1.2
and 3.2.2). To avoid shut down of the inverter due to over temperature, do not cover or block these suction /
exhaust openings or install the unit in an area with limited airflow. Keep a minimum clearance of 10” around
the unit to provide adequate ventilation. If installed in an enclosure, openings must be provided in the enclo-
sure, directly opposite to the air-suction and air-exhaust openings of the inverter.
Dry: There should be no risk of condensation, water or any other liquid that can enter or fall on the unit.
clean: The area should be free of dust and fumes. ensure that there are no insects or rodents. They may
enter the unit and block the ventilation openings or short circuit electrical circuits inside the unit.
Protection against fire hazard: The unit is not ignition protected and should not be located under any
circumstance in an area that contains highly flammable liquids like gasoline or propane as in an engine
compartment with gasoline-fueled engines. Do not keep any flammable / combustible material (i.e., paper,
cloth, plastic, etc.) near the unit that may be ignited by heat, sparks or flames.
closeness to the battery bank: Locate the unit as close to the battery bank as possible to prevent excessive
voltage drop in the battery cables and consequent power loss and reduced efficiency. However, the unit
should not be installed in the same compartment as the batteries (flooded or wet cell) or mounted where
it will be exposed to corrosive acid fumes and flammable oxygen and Hydrogen gases produced when the
batteries are charged. The corrosive fumes will corrode and damage the unit and if the gases are not venti-
lated but allowed to collect, they could ignite and cause an explosion.
Accessibility: Do not block access to the front panel. Also, allow enough room to access the AC receptacles
and DC wiring terminals and connections, as they will need to be checked and tightened periodically.
Preventing Radio Frequency Interference (RFI): The unit uses high power switching circuits that generate
rfI. This rfI is limited to the required standards. Locate any electronic equipment susceptible to radio fre-
quency and electromagnetic interference as far away from the inverter as possible.
