Locating and Mounting the Inverter
WARNINGS:
• Do not mount the inverter near any flammable or combustible
fluid or components.
• Provide adequate clearance/ventilation to the inverter. Do not
cover or obstruct any air vent openings and/or install in a zero-
clearance compartment.
The inverter should only be installed and mounted in a location that meets
the following requirements:
Clean and dry
– The inverter should not be installed in an area that allows
dust, fumes, insects, or rodents to enter or block the inverter’s ventilation
openings. This area also must be free from any risk of condensation, water,
or any other liquid that can enter or fall on the inverter.
Inverter failure under
these conditions is not covered under warranty.
Cool
– The inverter should be protected from direct exposure to the sun or
to any equipment that produces extreme heat. The ambient temperature
should be between 32° F (0° C) and 104° F (40° C); note that the inverter’s
output speci
fi
cations are rated at 77° F (25° C), so the cooler the better.
Ventilated
– In order for the inverter to provide full output power and
avoid over-temperature fault conditions, do not cover or block the inverter’s
ventilation openings, or install this inverter in an area with limited airflow.
Allow a minimum airspace clearance of 3” (7.6 cm) around the unit to provide
optimum ventilation.
Safe
– Keep any flammable/combustible material (e.g., paper, cloth, plastic,
etc.,) that may be ignited by heat, sparks, or flames at a minimum distance
of 2 feet (60 cm) away from the inverter. Do not install in any area that
contains extremely flammable liquids like gasoline or propane, or in locations
that require ignition-protected devices.
Close to the battery bank
– As with any inverter, it should be located as
close to the batteries as possible. Long DC wires tend to lose efficiency and
reduce the overall performance of an inverter. However, the unit should not
be installed in the same compartment as the batteries or mounted where it
will be exposed to gases produced by the batteries. These gases are corrosive
and will damage the inverter; also, if these gases are not ventilated and if
allowed to collect, they could ignite and cause an explosion.
Accessible
– Do not block access to the front or back of the inverter. Allow
room to view any indictors or digital display and to access the AC and DC
wiring connections—they will need to be checked and tightened periodically.
Orientating the inverter
- When mounted indoors, the CSW Series inverter
can be mounted on/underneath a horizontal surface (shelf or table) or on
a vertical surface (wall or bulkhead) with the DC terminals facing left or
right. Additionally, the CSW1012 and CSW2012 can be mounted with the DC
terminals facing up (CSW412 cannot be mounted with terminal’s facing up
or down)—do not mount with the DC terminals facing downward (see Figure
2-3). When mounted in an RV, mount flat on a horizontal surface only.
After determining your mounting position, use the base of the inverter’s chassis
as a template to mark your mounting screw locations (or, refer to the dimensions
in Figures 2-4 thru 2-6). Remove the inverter and drill pilot holes into the
mounting surface. Secure the inverter to the surface using the appropriate
corrosion-resistant hardware. If this unit is used in a mobile application, you
may want to place flexible washers or bushings between the mounting surface
and the inverter’s mounting flanges to reduce vibration.
