Backup
Caution
The EN751, EN761, and FN711 modules receive power supply from the main power unit (PS*)
for memory backup. If these modules are removed from the base unit, therefore, their memory
data will be deleted. Save the necessary data using the Engineering Tool before removing them
from the base unit.
