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 corro-
sion 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 12 inches of free air
space at the side and front 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. When
moving the charger after the packing skid and box have been
removed, make sure that lifting forks do not damage the charger
panels or cables.
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.
Stacking
Units with a single door can be stacked up to two units vertically.
Applications that require more than two units vertically stacked
will require shelf or rack systems not offered by E.P.M. Units with
two doors are not designed to be stacked. See options list for
stacking kits.

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 conclu-
sion 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 conduc-
tor 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, taking
care to make a 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 ground-
ing 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.
WARNING: ELECTRIC SHOCK HAZARD- Under no circumstance
should you use a grounding conductor with a current carrying ca-
pacity less than the ampere rating shown in Table 4-1.
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.
