E2620 Auxilliary Power Unit User Guide
Location
The APU should be mounted in a horizontal position and
protected from the elements and out of the way. The unit can be
mounted on a shelf with a retainer to prevent it from being
dislodged while in motion. The unit mount should also include
drain holes to prevent any water from accumulating.
Cooling Considerations
The airflow is from the rear intake louvers (at the sides) to the
front exhaust louvers, so a generous airspace over one inch
should be allowed for around both the intake and the exhaust
louvers as well as a straight and unimpeded access to open air.
The mount should not restrict or contain the air otherwise the
inverter will shut down due to excessive heat buildup.
Connections
Equipment power plugs can be plugged into the inverter, and the
access door closed to prevent any rain or snow from entering the
unit. The equipment power cables can be restrained with VELCRO
hook and loop fastener straps. The battery monitor should be
located where the operator can see the display and warning LEDs,
as well as operate the power switch. The battery monitor cable is
connected to the unit within the access door. It is a keyed twist
and turn connector.
Battery
The battery should be selected for capacity while considering the
weight. The battery should be mounted such that the battery
cable is free to move without strain. The battery cable is supplied
with a mating high power connector and fused leads for the
battery. The mating connector needs to be attached to the
battery enclosure in a manner that prevents rain entry.
