Battery Replacement
The WESROC

RMS Cellular Tank Monitor (CTM) uses a field replaceable, intrinsically
safe battery pack designed and supplied by Independent Technologies, Inc. The CTM
has been designed to operate on a very small amount of power, but eventually the
battery pack will need replacement. Because the battery pack is intrinsically safe, the
battery pack can be replaced at the tank without needing to remove the CTM to a safe
location. The following steps and photos illustrate how to replace the battery pack.
1] Remove the eight screws from around the perimeter of the battery pack.
2] Remove the battery pack from the bottom of the CTM enclosure and disconnect the
battery pack connector.
3] Connect the new battery pack to the CTM and arrange the battery pack cable to clear
internal obstructions.
4] Replace the battery pack into the bottom of the CTM enclosure and replace the eight
screws. Do NOT over tighten the screws and strip the threads from the bottom of the
CTM enclosure.
