To reduce risk of electric shock, unplug charger
from a live outlet or disconnect AC power to the
outlet before attempting any maintenance or
cleaning. Turning off controls will not reduce this
risk.
INTRODUCTION
This battery charger is a self-regulating charger with a
minimum of moving parts, designed for long, trouble-
free service. Built-in line voltage compensation
produces a consistent output when the AC supply
voltage varies by as much as 10% from nominal.
Convection cooling maximizes the reliability and
minimizes any maintenance costs. ONLY LIQUID
ELECTROLYTE (WET) LEAD ACID BATTERIES
should be recharged with this charger to ensure
superior battery performance and life. A patented
electronic circuit turns the charger on and off
automatically. When the battery has reached its
maximum state of charge, the circuitry will turn the
charger off.
RECEIVING AND INSTALLING THE CHARGER
When the charger is received, check for possible
in-transit damage. If any damage is found, it should
be reported as a claim to the carrier.
Proper installation of the charger is important in order
to achieve good charger performance and to prevent
damage to the charger and batteries. The charger
should be located in a clean, cool, dry, and well
ventilated area. To permit free air flow for convection
cooling, allow three inches (3") minimum between the
charger and any wall.
DANGER: TO REDUCE THE RISK OF FIRE, DO
NOT USE THE CHARGER NEAR FLAMMABLE
MATERIALS OR VAPORS.
AC INPUT
CAUTION: TO REDUCE RISK OF ELECTRIC
SHOCK OR FIRE, DISCONNECT POWER FROM AC
RECEPTACLE BEFORE INSTALLING, CHANGING
AC VOLTAGE OR REMOVING UNIT.
This battery charger must be connected to a 120
VAC, 60 Hertz, single-phase AC power source.
GROUNDING INSTRUCTIONS
This battery charger must be grounded to reduce the
risk of electric shock. This charger is equipped with
an AC supply cord having an equipment-grounding
conductor which must be connected to the ground
prong of an appropriate plug for the AC voltage being
used. This plug must be connected to an appropriate
AC outlet which is properly installed and grounded in
accordance with the National Electrical Code (U.S.)
and all local codes and ordinances.
DANGER: IMPROPER CONNECTION OF THE
EQUIPMENT-GROUNDING CONDUCTOR CAN
RESULT IN A RISK OF ELECTRIC SHOCK.
The conductor with insulation having an outer surface
which is green, with or without yellow stripe(s), is the
equipment-grounding conductor. If repair or
replacement of the AC supply cord or plug is
necessary, do not connect the equipment-grounding
conductor to a live terminal. Refer to a qualified
service agent.
EXTENSION CORD REQUIREMENTS
Always use a three-conductor, No. 14 AWG (1.5mm)
heavy duty cord with ground, properly wired, in good
electrical condition and keep it as short as possible.
Make sure the pins on the plug of the extension cord
are the same number, size and shape as the AC plug
of the battery charger. The use of an improper
extension cord could result in a risk of fire or electric
shock. Locate all cords so they will not be stepped
on, tripped over or otherwise subjected to damage or
stress.
DC OUTPUT
This battery charger is designed to produce a 48 volt
DC output with an initial charge current of 25 amps.
ONLY 48 VOLT, 24 CELL, SERIES CONNECTED,
180 TO 350 AMP-HOUR, LIQUID-ELECTROLYTE
(WET) LEAD-ACID BATTERIES SHOULD BE USED.
The charge current will decrease gradually to about 8
amps as the battery reaches full charge and will
remain there until the charger turns off. As the
battery ages, the charge current may no longer
decrease to the 8 amp finish current. Liquid
electrolyte batteries will normally be charged to 2.5-
2.6 volts per cell.
OPERATING INSTRUCTIONS
1.
Connect the DC output cable to the batteries.
The BLACK wire must be connected to battery
negative (-), and the RED or WHITE wire to
battery positive (+). Make sure all connections
are clean and tight.
2.
Connect AC supply cord to a properly grounded
120 volt, 60 Hertz, single-phase outlet.
3.
The charger will start after a short delay as
indicated by the transformer hum.
