2.3 Memory Backup Battery
A super capacitor (“super-cap”) and a coin type battery work together to
provide backup power for the static RAM and the real-time clock. This
helps to ensure retention of short and longer-term data, configuration, and
operational integrity when the FB107 is not in service or is in storage.
Note
:
You can replace the battery with a standard coin-type lithium
model CR2032 (DL2032).
Caution
To avoid circuit damage when working inside the unit, use
appropriate electrostatic discharge precautions (such as wearing a
grounded wrist strap).
When working on units located in a hazardous area (where explosive
gases may be present), make sure the area is in a non-hazardous
state before performing procedures. Performing these procedures in
a hazardous area could result in personal injury or property damage.
2.3.1 Removing and Installing the Battery
