battery about three inches (3") down from the top of
the battery. Make sure the spot is free of all dirt and
oil or the probe will not adhere properly. For proper
adhesion, the battery surface must be cleaned with
isopropyl alcohol.
Ideal application temperature
range is between 70 and 100°F. Initial application to
surfaces at temperatures below 50°F is not
recommended. Under cold conditions, the surface
should be warmed before application.
properly applied, low temperatures will not affect the
bond strength.
Remove the adhesive's protective strip and press
the probe firmly against the battery to ensure good
adhesion.
Securely fasten the temperature probe cable to
protect the probe from being torn from the
battery. Secure the probe's cable to a fixed object
to ensure the probe will not be pulled loose. Use a
cable tie mount on the battery or on the adjacent
battery, if necessary.
8. OPERATION
The battery charger is adjustable with the three
rotary switches on the front of the charger.
switches (settable between 20.00 and 39.99)
determine the float voltage for the batteries. SET
THE FLOAT VOLTAGE TO THE BATTERY
MANUFACTURER'S SPECIFIED VOLTAGE FOR
77°F. The charger will then electronically charge the
batteries to the voltage specified on the switches.
To set the switches, use a small screw-driver and
turn the switch so that the arrow head on the slot is
pointing to the desired number. Set the switches in
the following manner. If the desired battery voltage
is 26.8 volts, set the top switch to 2, the middle
switch to 6, and the bottom switch to 8 (see the
figure below). This will provide you with the proper
charging voltage.
BE SURE EACH SWITCH IS
SET ON A NUMBER AND NOT BETWEEN
NUMBERS. If a switch is set between numbers, the
output current will go to zero and the yellow charging
LED will flash.

The charger does not have a power switch. When
the AC power is applied to the charger, the DC
output will start and the yellow LED will be on. To
turn off the charger, disconnect the AC power
source.
9. MAINTENANCE
The battery charger requires minimal maintenance.
Once
It should be kept clean and all connections are to be
periodically tightened. BE SURE THE CHASSIS IS
SECURELY GROUNDED. If any problem cannot
be resolved, consult the nearest NRS service agent
at 1-800-357-3572.
10. SERVICING
If the battery charger operates improperly, follow the
steps below.
a. Begin by checking the voltage switches to
verify their settings against the specifi-
cations of the batteries.
b. Next, remove the small cover on the front of
the charger and make sure all of the binding
post nuts are tight. Also check the jumper
The
tap configuration for the AC voltage used.
c. Check the fuses to make sure they have not
blown.
d. Check the circuit breaker to see if it has
opened and push it in to reset it if
necessary.
e. Check the polarity between the DC output
and the battery and make sure their
connections are tight.
f.
If the steps above do not solve the problem,
contact your local NRS service agent at
1-800-357-3572.
