Maintenance and Troubleshooting 10-11
12-volt battery pack with PCB
Replace the internal battery in the TRITON+ monitor in the
following way:
1. Collect the data from the monitor (remotely or on-site). This
will reduce the risk of data loss once the battery is
disconnected.
2. Remove the monitor from the manhole, and disconnect the
antenna cable from the ANTENNA port on the monitor and the
sensor cable(s) from the corresponding port(s) on the monitor.
3. Move the monitor from the hazardous area (i.e., at least 20 feet
(6.1 m) away from the manhole), and place in a dry location.
4. Remove the 4 bolts securing the top to the canister using a 13-
mm nut driver.
5. Wipe away any debris or moisture that could enter the chassis
once the unit is opened.
6. Remove the top (with the attached power regulator dome) by
pulling it straight up from the canister. The battery rests at the
bottom of the canister, and an 18-inch long cable extends from
the battery pack to the top.
