INSTALLATION
A) Materials Provided
The PT-7 charger is provided completely assembled and ready for installation. The in-
staller must provide mounting hardware, as well as d.c. output wiring and connectors.
Proper sizes and gauges for the hardware, wire and connectors are noted in sections C
and D following. A warranty registration/customer satisfaction card has been included
in the packaging. Upon completion of the installation, please fill out this card and return
it to the factory. You will be contacted promptly if you have any problems with or ques-
tions about your Phase Three charger.
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 igni-
tion 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 mois-
ture, exhaust manifolds and battery fumes.
Vertical mounting is preferred. However, horizontal mounting is acceptable where abso-
lutely 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
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 # 10 screws (wood or machine screws, depending on mounting surface) with wash-
ers, are required to mount the charger.
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-
