5. AC ELECTRICAL SUPPLY
The charger must be connected to a single-phase,
50/60/100 Hertz AC power source, which can be
either 115 or 230 VAC depending on the charger
input voltage selection switch setting. Use an
appropriate size wire for the AC power input.
Quarter-inch (1/4") ring terminals are required for
proper connection to the AC input and ground
binding posts (A.A.R.) located on the front of the
charger. Open the small door cover on the front of
the charger by pulling out on the push tabs. Connect
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, 6 AWG or larger, 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 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.
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
to 3, and the bottom switch to 8 (see the Figure 8.1).
This will provide you with the proper charging
voltage. The tens digit is always a one (1) and
cannot be changed.
BE SURE EACH SWITCH IS
SET ON A NUMBER AND NOT BETWEEN
NUMBERS.
If a switch is set between numbers, the
