INSTALLATION
Location
For best operating characteristics and longest unit life,
take care in selecting an installation site. Avoid
locations exposed to high humidity, dust, high ambient
temperature, or corrosive fumes. Moisture can
condense on electrical components, causing corrosion
or shorting of circuits (especially when dirt is also
present).
Adequate air circulation is needed at all times in order
to assure proper operation. Provide a minimum of 6
inches of free air space at rear and sides of the unit.
Make sure that ventilation openings are not obstructed.
Always remove the charger shipping skid from the unit
before installation. The charger must be installed over
a noncombustible surface such as concrete or metal.
Keep the charging area clear of all combustible
material such as wood, paper, and cloth.
WARNING: SPARKS OR MOLTEN METAL
falling through open bottom can cause fire or
explosion.
•
Install over noncombustible material such
as concrete or metal.
•
Keep charging area clear of combustible
material.

Grounding
The frame of the power source must be grounded for
personnel safety. Where grounding is mandatory
under state or local codes, it is the responsibility of the
user to comply with all applicable rules and regulations.
Where no state or local codes exist, it is recommended
that the National Electrical Code be followed.
In addition to the usual function of protecting personnel
against the hazard of electrical shock due to fault in the
equipment, grounding serves to discharge the static
electrical charges which tend to build up on the
surfaces of equipment. These static charges can

cause painful shock to personnel, and can lead to the
erroneous conclusion that an electrical fault exists in
the equipment.
If a charger is to be connected to the AC power supply
with a flexible jacketed cable, one having a separate
grounding conductor should be used. When included
in cable assembly, grounding conductor will be green,
green with a yellow stripe, or bare. When connecting
input power to charger (as instructed in Line
Connection to Battery Charger section of this manual),
connect grounding conductor to equipment grounding
terminal (stud with a green nut and a cup washer and

good electrical connection. Connect other end of
grounding conductor to the system ground.
If, for any reason, an input cable which does not
include a grounding conductor is used, the equipment
must be grounded with separate conductor. Minimum
size and color coding requirements must be in
accordance with any applicable state or local code, or
the National Electrical Code.
If metallic armored cable or conduit is used, the metal
sheathing or conduit must be effectively grounded as
required by state or local code, or the National
Electrical Code.
If a system ground is not available, the charger frame
must be connected to a driven ground rod (at least 8 ft
[2438 mm] long), or to a water pipe that enters the
ground not more than 10 ft (3048 mm) from the
charger. A grounding conductor must be connected to
the rod or pipe in a manner that will assure a
permanent and effective ground. The conductor must
be sized in accordance with any applicable state or
local code, or by the National Electrical Code. If in
doubt, use the same size conductor as is used for the
conductors supplying power to the charger.
WARNING: ELECTRIC SHOCK HAZARD -
Under no circumstance should you use a
grounding conductor with a current
carrying capacity less than the ampere
rating shown in Table 4-1.
