III) INSTALLATION
) Materials Provided
A
The Phase Three charger is provided completely assembled and ready for installation. The installer must
provide four suitable 1/4" mounting screws/washers, as well as DC output wiring and connectors.
Proper sizes and gauges for the wire and connectors are noted in section D following.
B) Location
The charger should be mounted on a wall, bulkhead or other suitable mounting surface as close to the
batteries to be charged as possible. Do not mount the charger directly over the batteries as battery
fumes may cause excessive corrosion. The charger is ignition protected so it is acceptable to locate the
unit in an area where ignition protected equipment is required. The area should be well ventilated and
free from excessive moisture, exhaust manifolds and battery fumes.
Vertical mounting is preferred. However, horizontal mounting is acceptable where absolutely necessary.
Do not mount the charger where water, spray or condensation can occur, as this will shorten charger life.
It should not be located where there is a possibility of dust or debris being drawn into the unit through
the fan. A minimum of 2" clearance around the charger is recommended for proper cooling.
If the charger is located in an extreme heat area, such as an unventilated engine room, and maximum
operating temperature is exceeded, an automatic thermal protection circuit will shut the charger off.
Although it will return to service automatically after cooling sufficiently, thermal cycling will shorten the
life of the charger. If this condition occurs repeatedly, 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 AC input is located on the bottom of the
charger. If the factory‐installed AC 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‐31: A DC 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 DC 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. The provided drip shield is installed using the upper two mounting 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. 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.
