How to Replace the Batteries in a Honeywell 620-36?

[Nemez1963]

Hello, friends.
I use a Honeywell IPC PLC 620-36.
Now I need to replace the battery in Honeywell IPC PLC 620-36. If at this point I lose the power supply, I can lose the program in PLC (ladder)?

Thank you in advance for all of you.

The program in this PLC is backed up by the battery. As long as the main power is on, you can replace the battery without a problem. However, if the power supply fails (or there is a power outage) during the battery replacement you will lose the program.

It only takes a few seconds to replace the battery, it is always possible that a power outage can happen at that moment.
