3. Capacitive load
Capacitive loads can generate rush current 20 to 40 times the stationary current. Make sure that the rush
current does not exceed the current corresponding to the maximum specified resistance load. Capacitive
loads such as capacitors may be present in electronic circuit loads including inverters.
*About the maximum load specifications of the resistance load, refer to the specification for each model.

14.4.4 Procedures for replacing battery
When the battery voltage drops while the PLC power is on, the "BATT" LED on the panel is lit in red, and
M8005 and M8006 (latch) are turned on.
The memory can be retained for about one month after the lamps turn on. However, the operators may not
immediately find the lamps to be on. Prepare a new battery promptly, and replace the battery with the new
one.
