terminals on the side of the charger (see Figure 5.1).
Tighten the terminals using the screws on the front
of the charger. Torque terminal screws to 18 in-lbs.
(2N-m)
WARNING: FAILURE TO PROPERLY
CONNECT THE AC VOLTAGE CONDUCTORS
COULD CAUSE SERIOUS DAMAGE TO THE
CHARGER. BE SURE TO SET THE VOLTAGE
SELECTION SWITCH ON THE SIDE OF THE
CHARGER TO THE PROPER POSITION.
WARNING: DO NOT OPERATE THE
CHARGER WITHOUT PROPER GROUNDING.
IMPROPER GROUNDING CAN RESULT IN THE
RISK OF AN ELECTRIC SHOCK.

6. DC
OUTPUT
THE AC POWER TO THE CHARGER SHOULD
ALWAYS BE DE-ENERGIZED WHILE MAKING
CONNECTIONS TO THE CHARGER TERMINAL
STRIP.
The DC output wires should be stripped
0.375 inches (9.5mm). Insert the DC output wires
into the proper terminals on the side of the charger
(see Figure 5.1). Tighten the terminals using the
screws on the front of the charger. Torque terminal
screws to 18 in-lbs. (2N-m) Check to make sure the
polarity of the DC output wires are the same as
those connected to the battery. The charger will not
operate in a reversed polarity condition.
WHEN
CONNECTING THE DC WIRES TO THE
CHARGER WITH THE AC POWER
DISCONNECTED, A SPARK MAY OCCUR.
This is
caused by the output capacitors being charged by
the batteries. If the DC polarity is reversed, a circuit
breaker will protect the charger from internal
damage. Correct the reversed wires and push the
circuit breaker button back in.
WARNING: DO NOT TOUCH THE
CHARGER'S TERMINALS OR AN ELECTRICAL
SHOCK COULD OCCUR. A VOLTAGE IS
PRESENT ON THE DC TERMINALS EVEN AFTER
THE AC IS DISCONNECTED BECAUSE OF THE
ENERGY STORED IN THE CAPACITOR.
7. TEMPERATURE
PROBE
The external temperature probe is an optional way of
extending battery life by using temperature
compensation. One end of the temperature probe
cable has a three-pin plug, which plugs into a
receptacle labeled TEMP PROBE on the bottom
of
the charger. The other end of the cable has the
temperature sensor sealed in a terminal.
WARNING: IT IS IMPORTANT TO MOUNT
THE TEMPERATURE PROBE ON THE
BATTERIES FOR PROPER TEMPERATURE
COMPENSATION. IF THIS CANNOT BE DONE,
LOCATE THE PROBE AS LOW AS POSSIBLE IN
THE BUNGALOW OR CABINET.
Terminal-Type Probe
The terminal-type probe should be attached to the
negative (-) battery post near the center of the
battery pack. If the threaded stud is long enough
above the battery jumper nut, attach the probe with
another nut. Torque this nut to proper specifications.
If the stud is too short, the nut holding the jumper
wire will need to be removed. Open or remove the
load and charging circuits to the batteries. Remove
the nut holding the jumper and add the probe, then
torque the nut to the proper specifications. Then
close or connect the load and charging circuits back
to the batteries.
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. The
switches (settable between 10.00 and 17.00)
determine the float voltage for the batteries.

THE FLOAT VOLTAGE TO THE BATTERY
MANUFACTURER'S SPECIFIED VOLTAGE FOR

°
F.
The charger will then electronically charge the
batteries to the voltage specified on the switches. To
set the switches, use a small screwdriver and turn
the switch so that the arrowhead on the slot is
pointing to the desired number. Set the switches in
the following manner: If the desired battery voltage is
