the charger should be relocated. For optimum performance and longer life the charger
should not be located in an area of extreme high temperature.
C) Mounting
Important Pre-Installation Note
: The wiring access port for a.c. input is located on the bottom
of the charger. If the factory-installed a.c. cord must be changed for any reason, this should
be done before mounting, as access will be difficult afterwards.
The charger may be mounted on either a metal or non-metal surface*. You will require four
screws (wood or machine screws, depending on mounting surface) with washers, sized for 1/
4" holes, to mount the charger, plus two temporary holding screws. Note that, in addition to
the four permanent mounting holes in the flanges, there is a hole in each mounting flange
which is “keyhole” shaped. This is provided to ease vertical installation.
*Per ABYC A-20: A d.c. chassis grounding conductor shall be connected from the case
of the battery charger to the engine negative terminal or its bus, and must not be more than one
size under that required for the d.c. current-carrying conductors, and not less than 16 AWG.
Make a mark on the wall or bulkhead where each of the keyhole slots will be located. Then
drive a screw about halfway in at each of these marks. Hang the charger onto the bulkhead
using the keyhole slots. Doing this will save you from having to support the charger’s weight
while you are driving in the four permanent mounting screws. Note: The keyhole slots may
be used for additional support screws but they are not to be used as permanent mounting
points by themselves.
IMPORTANT: Although the charger is constructed of materials and in a manner which
makes it highly resistive to the corrosive effects of moisture in the environment, the
charger is not water-resistant. Do not mount the charger where there is a possibility
of water entering the unit. Evidence of water entry into the charger will void the
warranty.
D) d.c. Output Wiring
Note: Only qualified service personnel should access the output terminals of the charger.
The installer will need to provide output wires and four 1/4" ring lug connectors (for attach-
ing wires to output terminals). Use the table below to determine the correct gauge wire,
based on the length of the wire run from the charger to the batteries.
