4.1 Safety of inStaLLation
WarninG!
Please read safety instructions in Section 1 before commencing installation.
When using the unit as a backup AC Power Source, Grid AC Power Input should
be fed from 15A/20A, GfCI Protected outlet.
4.2 inStaLLation environment
For best operating results, the unit should be placed on flat surface, such as the ground, car
floor, or other solid surface. The power cord allows easy positioning of the unit. The unit
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 unit. In all ma-
rine applications, do not install the unit 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 the unit 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
power. 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 unit on or near a heating vent or any piece of equipment
which is generating heat above room temperature. Keep the unit away from direct sunlight.
ventilated - The unit is cooled by 2 load-controlled fans. The fans will switch oN automati-
cally at load ≥ 85W when the Inverter is supplying power, and at 3A ± 1A charging current
when in battery Charging/AC Pass Through Mode. The fans draw cool air from the air
intake ventilation slots on the AC outlet side (14, Fig 3.1) and discharge hot air out of the
fan openings (13, Fig 3.1) 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
air intake ventilation slots and fan openings for air discharge are not blocked. Do not place
other items on or over the unit during operation.
4.3 mountinG orientation
Two (2) flanges on the bottom with 2 mounting slots each are provided for mounting, as
shown in fig 3.2.
If the unit 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 (13, Fig 3.1) for fan air discharge.
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 considerations. If mounted as in Fig 4.1(b), metallic or other
conductive object(s) may accidentally fall inside the unit through the fan ventilation
openings 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
floor and may create fire hazard.
