6. DC OUTPUT
The DC output wires 8 AWG or larger, are
connected on the two right-most binding posts as
labeled on the panel behind the binding 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 is 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.

of the binding post nuts.
WARNING:
DO

SHOCK COULD OCCUR.
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.

LOCATE THE PROBE AS LOW AS POSSIBLE IN

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 specifi-
cations. If the stud is too short, the nut holding the
jumper wire will need to be removed.
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.
