HMIGXO panels include a RTC to provide system date and time information, and to support related functions requiring a real-time clock. To continue to keep time when power is off, a non-rechargeable but replaceable battery is provided with HMIGXO3502 and HMIGXO5502 panels.
NOTE: The HMIGXO3502 and HMIGXO5502 have an inner protective circuit which can sustain it for 2 minutes when exchanging the RTC battery.
Installing and Replacing the RTC Battery
While lithium batteries are preferred due to their slow discharge and long life, they can present hazards to personnel, equipment and the environment, and must be handled properly.

Insert the new battery in the compartment in accordance with the polarity markings in the compartment and on the battery. |
|
5 |
Close the cover and verify that the latch clicks into place. |
|
6 |
Power up your HMIGXO. NOTE: If you do not power up your HMIGXO immediately, the external backup battery life might be reduced. |
