The charger can be mounted either on a wall or in a standard 23” relay rack. Locate the charger in a dry
place as close to the battery and load as possible to minimize voltage drop.
WARNING
: These chargers are
not
approved for operation in mines or other places with explosive
atmospheres
Wall Mounting
Mount the system to a robust wall using 1/4” bolts with flat washers behind the mounting holes if
necessary to level the charger on an uneven wall. The charger should be located as close to the battery
and load as possible to reduce voltage drop in the charging leads. Refer to the mechanical drawings at the
end of this document for case dimensions and mounting dimensions.
Relay Rack Mounting
The charger is shipped on its back with the mounting flanges in the wall-mount position. Place the
charger in a vertical position, then unbolt and reverse the mounting flanges.
CAUTION: When changing
the angles from wall mount (the standard shipping configuration) to rack mount, you MUST either stand
the charger up vertically, or otherwise remove the charger’s weight from the rack angles when removing
the rack angle bolts. If you do not, the bolts in heavy chargers may strip on their way out.
Protect the charger from construction grit, metal chips, paint or other debris. Clean away debris after
installation and before turning on the charger.
Ventilation
The charger is designed to be convection cooled. Required clearances around the unit for proper cooling
are 6 inches on the top and 4 inches on the bottom.

enclosure while the charger is operating.
Remove the two 1/4-turn fasteners securing the charger's top front panel and open the front panel. Make
