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*.
*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.
Four screws (wood or machine screws, depending on mounting surface) with washers,
sized for 1/4" holes, are required to mount the charger. An additional two temporary
holding screws will ease vertical installation.
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. 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 key-
hole 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 environ-
ment, 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
attaching 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.
