Replacing the Timekeeper Battery

The NI-3101-SIG uses a combination lithium battery and clock crystal package called a Timekeeper.
Only one Timekeeper unit is installed within a given NI-3101-SIG. The battery can be expected to have
up to 3 years of usable life under very adverse conditions. Actual life is appreciably longer under normal
operating conditions. This calculation is based on storing the unit without power in 50° C (120° F)
temperature until battery levels are no longer acceptable. The part number for a replacement battery is
57-0032.
To replace the Timekeeper battery:
1. Discharge the static electricity from your body by touching a grounded metal object.
2. Unplug all the connectors from the device.
3. Remove the rear panel from the device, and then disconnect the NXI control cable and remove the
Master card.
4.
Locate the battery behind the Configuration Port on the circuit board.
5. Carefully slide the battery out of its socket and insert the new battery.
6.
Plug the 2-pin 3.5 mm mini-Phoenix PWR (green) connector to reapply power. Wait approximately
1 minute, then remove the PWR connector again.

8.
Re-connect the NXI control cable to the Master card.
9. Replace and secure the rear faceplate using the mounting screws and reconnect all communication
connectors.
