DC OUTPUT
This battery charger is designed to produce a 36 volt
DC output with an initial charge current of 25 amps.
ONLY 36 VOLT, 18 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.
WARNING: LEAD ACID BATTERIES
GENERATE GASES WHICH CAN BE EXPLOSIVE.
CHARGE ONLY IN WELL VENTILATED AREAS.
DO NOT DISCONNECT CHARGER DC OUTPUT
TERMINALS FROM BATTERY WHEN CHARGER
IS ON. THE RESULTING ARCING AND BURNING
COULD CAUSE THE BATTERY TO EXPLODE.
KEEP SPARKS, FLAME, AND SMOKING
MATERIALS AWAY FROM BATTERY.
If the charger must be stopped, always discon-
nect the AC supply cord from its outlet before
disconnecting the DC output terminals from the
battery.
4.
The initial charge current should range between
approximately 20 to 29 amps. If the batteries
have not been discharged, or the AC supply
voltage is lower than 120 volts, the initial charge
rate may be less. If the batteries have been
excessively discharged, or AC supply voltage is
higher than 120 volts, the initial charge rate may
be more.
5.
Charge current will gradually taper to
approximately 8 amps depending on the age
and condition of the batteries. Charger turns off
automatically when battery is fully charged.
Charge time varies with battery size and depth
of discharge. Allow 11-15 hours for normal
charging. Severely discharged batteries may
require more time to be properly charged and
equalized.
6.
After the charger has turned off, disconnect the
AC supply cord from outlet.
MAINTENANCE INSTRUCTIONS
The battery charger requires minimal maintenance.
It should be kept clean and all connections tightly
secured. In the event of intermittent operation,
examine and tighten, if necessary, all connections.
BE SURE THE CHASSIS IS SECURELY
GROUNDED. If any problems cannot be resolved,
consult a qualified service center.
Observe the following battery maintenance
procedures to obtain good performance and
maximum cycle life.
1.
Always observe the following personal safety
precautions when working with lead acid
batteries:
a.
Someone should be within range of your
voice or close enough to come to your aid
when you work near a battery.
b.
Have plenty of fresh water and soap nearby
in case battery acid contacts skin, clothing
or eyes.
c.
Wear complete eye protection and clothing
protection. Avoid touching eyes while
working near battery.
d.
If battery acid contacts skin or clothing,
wash immediately with soap and water. If
acid enters eye, immediately flood eye with
running cold water for at least 10 minutes
and get medical attention.
e.
NEVER smoke or allow a spark or flame in
the vicinity of batteries.
f.
Be extra cautious to reduce risk of dropping
a metal tool onto battery. It might spark or
short-circuit battery or other electrical part
that may cause explosion.
g.
Remove personal metal items such as rings,
bracelets, necklaces, and watches when
working with a lead acid battery. A lead acid
battery can produce a short-circuit current
high enough to weld a ring or the like to
metal, causing a severe burn.
h.
NEVER charge a frozen battery.
DANGER: TO REDUCE RISK OF ELECTRIC
SHOCK, ALWAYS DISCONNECT THE AC
SUPPLY CORD FROM ITS OUTLET AND THE DC
OUTPUT CORD FROM THE BATTERY BEFORE
ATTEMPTING ANY MAINTENANCE (CHANGING
FUSES, ETC.) OR CLEANING OF THE BATTERY
OR BATTERY CHARGER.
