and the RED or WHITE wire to battery positive
(+). Make sure all connections are clean and
tight.
3. The charger will start after a short delay as
indicated by the transformer hum and the
ammeter movement.
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
disconnect the AC supply cord from its outlet
before disconnecting the DC output terminals
from the battery.
4. Monitor the ammeter for connect charge current.
The initial charge current should be
approximately 20 amps. If the battery has not
been discharged, or the AC supply voltage is
lower than 230 volts, the initial charge rate may
be less than 20 amps.
5. Charger turns off automatically when battery is
fully charged. Charge time varies with battery
size and depth of discharge. Allow 8 hours for
normal charging. Severely discharged batteries
may require up to 12 hours to be properly
charged and equalized. After the charger has
turned off, disconnect the DC output plug from
the battery and the AC supply cord from outlet.
MAINTENANCE INSTRUCTIONS
The battery charger requires minimal maintenance.
It should be kept clean and all connections are to be
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 ten 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.
2. New batteries should be given a full charge
before their first use because it is difficult to
know how long batteries have been stored.
3. Limit use of new batteries for first five cycles.
New batteries are not capable of their rated
output until they have been discharged a
number of times.
4. Do not excessively discharge batteries.
Excessive discharge can cause polarity reversal
of individual cells resulting in complete failure
shortly thereafter. Limited use of new batteries
will minimize the chance of cell reversal.
5. CHECK THE LEVEL OF THE ELECTROLYTE
IN CONVENTIONAL LIQUID ELECTROLYTE
LEAD ACID BATTERIES MONTHLY.
MAINTAIN THE PROPER ELECTROLYTE
LEVEL BY ADDING DISTILLED OR PURIFIED
WATER WHEN NECESSARY. Electrolyte
levels lower during discharge and rise during
charge. Therefore, it is mandatory that water be
added to cells ONLY when they are fully
charged; do not overfill. Old batteries require
more frequent additions of water than new
batteries.
6. Keep tops of batteries clean and dry to prevent
excessive self-discharge. Keep battery terminals
reasonably tight.
