Installation
WARninG!
1. Before commencing installation, please read the safety instructions explained
in the Section titled “Safety Instructions” on page 3.
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 super-
seded by the National / Local Electrical Codes related to the location of the
unit and the specific application.
Location of installation
Please ensure that the following requirements are met:
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 generated by other adjacent heat generating devices.
Well ventilated: The unit is cooled by convection and by forced air-cooling by tempera-
ture controlled fan(s). The fan(s) sucks cool air from air intake openings on the bottom
in PST-60S / 100S and from bottom / sides / top in PST-150S / 200S and expels hot air
through the exhaust openings next to the fans. To avoid shut down of the inverter due
to over temperature, do not cover or block these intake / 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 enclosure, directly opposite to the air intake and 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 elec-
trical 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.
