4.5 Testing the Back-up Battery (Inside the Rating Plug)

The battery has no part in the protection function of the Trip Unit .
The battery is provided only to maintain the "RED" LED indication of
the cause of TRIP in the Digitrip RMS 610 Trip Unit when external
control power to the Power / Relay Module is not available . The
battery is located in the rating plug along with a battery check push-
button and a green battery check LED (see Figure 9) .

4.5.1 Back-up Battery Check

The battery is a long life, lithium photo type unit . The status of the
battery can be checked at any time . Press and hold the "battery
check push-button and observe the "Green" LED as shown in Figure
9 . If the battery check LED does not light "Green", replace the bat-
tery . 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 . If however,
control power is lost and the battery is dead, the cause of TRIP LED
will not be lighted "RED" .

4.5.2 Replacing the Back-up Battery

The battery can be easily replaced from the front of the Trip Unit by
lowering the hinged cover of the rating plug as shown in
Figure 9 . The battery can then be removed by pulling the battery
tab as shown in Figure 9 . After the battery is replaced (or after an
Auxiliary Power Module is plugged into the Trip Unit), one or more of
the cause of Trip LED'S may be illuminated . It is necessary to press
and release the "TRIP RESET button to turn off any of the LEDs that
may be illuminated . Failure to do so can cause the battery to run
down again . The Trip Unit will then be ready to indicate the next
cause of trip .
N otee: 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 pro-
tection function .
CAUTION
CARE SHOULD BE EXERCISED WHEN REPLACING THE BATTERY TO INSURE
THAT THE CORRECT POLARITY IS OBSERVED. POLARITY MARKINGS ARE
VISIBLE ON THE RATING PLUG WHEN THE HINGED COVER IS OPEN AS
INDICATED IN FIGURE 9. IF THE BATTERY IS INSERTED WITH INCORRECT
POLARITY, AND IF THE 120 VAC CONTROL POWER TO THE POWER RELAY
MODULE IS LOST, THEN, AFTER AN OVER CURRENT OR SHORT-CIRCUIT
TRIP, NO LEDS WILL BE LIGHTED RED TO INDICATE THE REASON FOR THE
TRIP.
The replacement battery should be the same type or equivalent .
Acceptable 3 .0 volt lithium batteries may be obtained as type desig-
nation CR 1/3N or DL 1/3N .
