6.0 TRIP UNIT BATTERY
6.1 General
The battery plays no part in the protection function of the
trip unit.
Activate the battery by removing the Battery Insulating Tab
by taking out the battery and then removing and discarding
the tab. (See Figure 6.1).
As indicated in Figure 3.1, the battery is provided to
maintain the red LED indication of the "cause of trip" in the
Digitrip. The battery is located behind the rating plug door.
A Reset/Battery Test pushbutton and a green Battery
Check LED are located on the trip unit.

6.2 Battery Check
The battery is a long-life, lithium, camera-type cell. Check
the status of the battery at any time by pressing the
Reset/Battery Test 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 indicators. The trip unit will now be ready to indicate
the next cause of trip.
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.
The replacement battery should be the same type as
found in in the trip unit or proper equivalent. Acceptable
3.0 volt lithium batteries may be obtained from the follow-

6.3 Battery Installation and Removal
The 3-volt lithium cell battery (See Figure 6.1) can easily
be 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.
Cover door should now flip open. Remove the old battery
by pulling up on the removal tab that wraps under the cell.
When inserting the new battery, pay special attention to
ensure that the proper polarity is observed. The main body
of the battery is the positive (+) side.
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.
