Replacing the Battery
Back-up
A 4.5 volt alkaline battery (Part Number 145486 00A) is installed as a back-up in case
the power to the unit should fail. You should check the battery periodically to ensure it is
working properly and change it as necessary. Refer to the Battery Back-up Test section
later in this chapter.
CAUTION
DISCONNECTING BOTH THE POWER SUPPLY AND THE BATTERY BACK-UP CAN
RESULT IN LOSS OF ALL PROGRAMMING.
To replace the battery back-up:
1. Disconnect AC power to the terminal.
2. Disconnect the power cable at the rear of the unit. Remove the back cover for
General Purpose units.
3. Using a Phillips head screwdriver, remove the two screws located on the top and
bottom of the power supply assembly, freeing it from the power supply housing.
General Purpose units have only a top screw.
4. Carefully pull the power supply assembly toward you and slide the assembly from
the JAGXTREME terminal’s enclosure. Disconnect the battery harness from J3.
CAUTION

DISPOSED OF IN FIRE. DISPOSE OF BATTERY PROPERLY.
5. Remove the old battery and install the new battery ensuring that pin 1 on J3 is on
the (+) side (red wire) of the battery. Connect the battery harness to J3 on the
power supply and slide it back into the JAGXTREME terminal.
6. Replace and tighten the power supply retention screws removed in step 3.
7. Reconnect the power cable, replace the cover if working with a general purpose
unit, and reapply power.
WARNING!
IMPROPER INSTALLATION OF THE POWER CABLE WILL RESULT IN APPLYING 120
VAC TO GROUND. THE HOT WIRE MUST BE ON TOP. THE TERMINAL SCREWS
