2.1.3 Locating the Inverter
Only install the inverter 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. The inverter

uses stainless steel fasteners, plated copper buss-bars, a power-coated aluminum base and the

internal circuit boards are conformal coated all done to help fi ght the harmful effects of corrosive

environments. However, the life of the inverter is uncertain if used in these type of environments,

and inverter failure under these conditions is not covered under warranty.

Info: If the inverter is installed in an area where moisture may occur, we recommend

putting silicone dielectric grease compound into the electrical ports (items 3 - 6 as shown

in fi gure 1-1).

Before installing the accessory cables or if leaving any ports open, squirt

a liberal amount into each port. Silicone dielectric compound makes an

effective moisture

and corrosive barrier to help protect and prevent corrosion to the RJ11 connections.

Cool - The inverter should be protected from direct sun exposure or equipment that produces

extreme heat.

Info: The ambient temperature around the inverter must not exceed 77°F (25°C) to meet

power specifi cations.

Ventilation - In order for the inverter to provide full output power and avoid overtemperature

fault conditions; do not cover or block the inverters ventilation openings or install this inverter

in an area with limited airfl ow. The inverter uses two internal fans to provide forced air cooling,

these fans pull in air through the intake vents (see item 9 in fi gure 1-2) and blow out air through

the exhaust vents (see item 13 in fi gure 1-3). Allow at the minimum, an airspace clearance of 6”

at the intake and exhaust vents and 3” everywhere else to provide adequate ventilation.
If the inverter is installed in an enclosure, a fresh air intake opening must be provided directly to

the front side (intake vents) of the inverter and an exhaust opening on the back side (exhaust

vents) of the inverter. This will allow cool air from the outside to fl ow into the inverter and heated

air to exit from the inverter and out of the enclosure. When mounted in an enclosed compart-

ment, airfl ow must be at least 100 cfm in order to maintain no more than a 68°F (20°C) rise in

compartment temperature.

CAUTION: Do not mount this inverter in a zero clearance compartment. Do not cover

or obstruct the ventilation openings - overheating may result.

Safe - Keep any fl ammable/combustible material (i.e. paper, cloth, plastic, etc.) that may be

ignited by heat, sparks or fl ames at a minimum distance of 2 feet away from the inverter. Do not

install this inverter in any area that contains extremely fl ammable 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 loose effi ciency 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. The absolute maximum recommended battery cable length is 15 feet.
Accessible - Do not block access to the inverter’s remote control and accessory ports as well

as the inverter’s controls and status indicator. Also allow enough room to access the AC and DC

wiring terminals and connections, as they will need to be checked and tighten periodically. See

fi gure 2-3 for the MS-AE Series inverter/charger dimensions.
Away from sensitive electronic equipment - High powered inverters can generate levels of RFI

(Radio Frequency Interference). Locate any electronic equipment susceptible to radio frequency

and electromagnetic interference as far away from the inverter as possible.
