Replacing the Lithium Batteries
The NXC-ME260 is equipped with two lithium batteries (FG57-0013) that have a life of
approximately 2.5 years to protect their memory. When DC power is on, the batteries (FIG. 15) are
not used. When replacing the batteries, remove one at a time to avoid losing the program in
memory.
1. Discharge the static electricity from your body by touching a grounded metal object.
2. Unplug all the connectors from the Controller or Module.
NetLinx Integrated Controller (NXI): Remove the rear panel from the NXI. Then,
disconnect the NXI control cable and remove the Master card.
NetLinx Module (NXS-xxx): Remove the rear panel from the Module, and remove the
Master card.
3. Locate the two batteries behind the Program port on the NXC-ME260 circuit board.
4. Carefully slide one battery out of its socket and insert the new battery.
5. Plug the 2-pin PWR (green) connector to reapply power. Wait approximately 1 minute. Then,
remove the PWR connector again.
6. Carefully slide the other battery out of its socket and insert the new battery.
7. Replace the Master card (re-connect the NXI control cable to the Master card if replacing in an
NXI).
8. Replace and resecure the rear faceplate using the mounting screws and reconnect all
communication connectors.
9. Reconnect the 12 VDC power supply to the respective PWR connector and apply power.
