This is a battery-voltage level indicating that battery power is low and that the user must
take action in light of the imminent break in the supply of power to the load.
Rotary switch controlled by the user, used to connect the equipments directly to the AC
source. Transfer of the equipments to the manual bypass enables UPS maintenance
without interrupting the supply of power to the connected equipments.
Normal source of power for the UPS.
The normal UPS operating mode in which the AC source supplies the UPS which in turn
