POINT
1. Do not use the battery exceeding its guaranteed life.
If it is expected that the battery may exceed its guaranteed life, take the
following measures:
• Back up programs and the error/operation history in advance after SM52
turns on (within the power failure compensation time after alarm
occurrence).
2. The life of Q6BAT is 5 years when not connected to a CPU module.
3. When the battery-low special relay SM52 turns on, immediately change the
battery.
If an alarm has not yet occurred, it is recommended to replace the battery
periodically according to the conditions of use.
