the AC power terminals on the two posts on the right,
as marked on the panel behind the posts. Connect
the AC ground to the terminal lug provided.
WARNING: FAILURE TO PROPERLY
CONNECT THE AC VOLTAGE CONDUCTORS
COULD CAUSE SERIOUS DAMAGE TO THE
CHARGER. BE SURE TO SET THE VOLTAGE
SELECTION SWITCHES ON THE FRONT OF THE
CHARGER TO THEIR 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 DC output wires are connected on the two left-
most binding posts as marked on the panel behind
the posts (positive on the left and negative on the
right). The DC cables should have quarter-inch (¼")
ring terminals for connecting them to the binding
posts. 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. Close the door cover
on the front of the charger after tightening all of the
binding post nuts.
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 front
of the
charger. The other end of the cable has the
temperature sensor sealed either in a terminal or
small metal box.
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.
Box-Type Probe
The metal box has a high performance contact
adhesive tape for attaching it to the battery. To
attach, clean a spot for the probe on the middle
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. Once 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. The
switches (settable between 10.00 and 17.00)
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 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
13.38 volts, set the top switch to 3, the middle switch
