Safety of Installation
Please read safety instructions on pages 1-2 before commencing installation.
Installation Environment
Forbestoperatingresults,theinvertershouldbeplacedonatsurface,suchastheground,
caroor,orothersolidsurface.Thepowercordallowseasypositioningoftheinverter.The
inverter should only be used in locations that meet the following criteria:
Dry- Do not allow water and/or other liquids to come into contact with the power inverter. In
all marine applications, do not install the inverter below or near the waterline and keep the
inverter away from moisture or water.
If Flooded / Wet Cell Type of battery is being used, ensure that it is not installed very close to
the battery to avoid contact with acid / acid vapors
Cool - Ambient air temperature should be between 0°C (32°F) to 25°C (77°F) for full rated pow-
er. At higher temperature of 26°C (79°F) to 35°C (95°F), the output power should be de-rated to
80%.Donotplacetheinverteronornearaheatingventoranypieceofequipment,whichis
generating heat above room temperature. Keep the inverter away from direct sunlight.
Ventilated - The unit is cooled by load-controlled fan. The fan will be off up to certain thresh-
old of power and automatically switch on thereafter. The fan sucks cool air in from the venti-
lation slots on the AC outlet side and discharges hot air out of the fan opening (9) on the DC
Input Terminal side. Keep the areas surrounding the inverter clear by at least 10 cm to ensure
free air circulation around the unit. Ensure that the ventilation slots and fan opening on the
sides are not blocked. Do not place items on or over the inverter during operation.
Mounting Orientation
SAM-250-12 Model (Fig 3.1) is not provided with mounting arrangement. SAM-450-12 (Fig
3.2)andSAM-800-12(Fig3.3)Modelsareprovidedwith2angesonthebottomwith2
mounting slots each.
If the inverter is required to be mounted on a vertical surface like a wall, please ensure that
thefanaxisishorizontalasshowninFig4.1(a).
TheDCinputsidehaslargerventilationopeningsforfanairow.Mountingwiththefanside
facing up or down as shown in Figs 4.1(b) or 4.1(c) is NOT permitted due to safety consider-
ations. If mounted as in Fig 4.1(b), metallic or other conductive object(s) may accidentally fall
inside the unit and create hazardous condition resulting from short circuit of internal high
voltage section(s). If mounted as in Fig 4.1(c), hot / molten material from damaged internal
portionoftheunitduetomalfunctionmayfalloncombustiblematerialontheoorandmay
createrehazard.
