Replace the Battery
A lithium battery is used by the real-time clock and static RAM; it is
not used for application backup or retention. The clock module has a
life expectancy of two years without power.
To replace the battery:
1. Disconnect power from the terminal.
2. Place the terminal, display side down, on a flat stable surface.
3. Detach the communication module (if attached) from the logic
module by removing the four screws.
4. Loosen the six captive screws that attach the logic module to the
display module.
WARNING
When you connect or disconnect the battery an
electrical arc can occur. This could cause an
explosion in hazardous location installations. Be sure
that power is removed and the area is nonhazardous
before proceeding. Replace the battery only with the
indicated catalog number.
For Safety information on the handling of lithium
batteries, including handling and disposal of leaking
batteries, see Guidelines for Handling Lithium
Batteries, publication AG 5-4.
Do not dispose of battery in a fire or incinerator.
Dispose of used batteries in accordance with local
regulations.
Store batteries in a cool, dry environment. We
recommend 25 °C with 40 to 60% relative humidity.
You may store batteries for up to 30 days between
-45 to 85 °C, such as during transportation. To avoid
possible leakage, do not store batteries above 60 °C
for more than 30 days.
