NOTE:
The battery can be replaced at any time, even
while the circuit breaker is in-service, without affecting the
operation of the circuit breaker or its protection functions.
CAUTION
EXERCISE CARE WHEN REPLACING THE BATTERY TO
ENSURE THAT THE CORRECT POLARITIES ARE
OBSERVED. POLARITY MARKINGS ARE SHOWN ON
THE RATING PLUG WHEN THE HINGED COVER IS
OPEN. ACCIDENTALLY INSTALLING THE BATTERY IN
THE REVERSE DIRECTION WILL NOT HARM EITHER
THE TRIP UNIT OR THE BATTERY, BUT WILL DEFEAT
THE FUNCTION OF THE BATTERY.
The replacement battery should be the same type as that
already in the trip unit or an equivalent. Acceptable 3.0 volt
lithium batteries may be obtained from the following

6.0 TRIP UNIT BATTERY
6.1 General
The battery plays no part in the protection function of the
trip unit.
As indicated in Figure 3.1, the battery is provided to
maintain the red LED indication of the Cause of Trip. The
battery is located under the rating plug door. A battery
check pushbutton and a green Battery Check LED is also
provided. On the initial installation of the circuit breaker,
Pull to Remove Battery and discard the insulating tab and
then replace battery. (See Figure 6.1) This will activate the
battery. Check the battery status by depressing the
battery test pushbutton.
6.2 Battery Check
The battery is a long-life, lithium, camera-type unit. Check
the status of the battery at any time by pressing the
Battery Check pushbutton and observing the green LED.
If the Battery Check LED does not light green, replace the
battery. The condition of the battery has no effect on the
protection function of the trip unit. Even with the battery
removed, the unit will still trip the breaker in accordance
with its settings. However, without the battery, the Cause
of Trip LED will not flash red. If the battery is replaced, one
or more of the Cause of Trip LEDs may be illuminated.
Push the Reset/Battery Test button to turn off the indica-
tors; the trip unit will be ready to indicate the next cause of
trip.
NOTE:
A healthy battery is required to fully reset the 4 bit
Latch chip and associated cause of trip LEDs (See Figure
3.1).
6.3 Battery Installation and Removal
The 3-volt lithium cell battery
(See Figure 6.1)
is easily
removed and replaced. The battery is located in the cavity
adjacent to the rating plug mounting screw, but is not part
of the rating plug. Insert a small screwdriver at the left side
of the rating plug, and to the left of the word OPEN, to
open the rating plug door. Remove the old battery by
pulling up on the removal tab that wraps under the battery
cell. When inserting the new cell, pay special attention to
ensure that the proper polarity is observed. The main body
of the battery is the positive (+) side.
