for the UPS will still be active.
Battery Mode Shutdown can be performed locally or remotely:
Battery Mode Shutdown can be performed locally or remotely:
• Local Battery Mode shutdown can be performed by shorting the pins in Set 4.
• Remote Battery Mode Shutdown can be performed using a switch connected to the pins in Set 4
• Remote Battery Mode Shutdown can be performed using a switch connected to the pins in Set 4
and mounted at remote location.
Activation of the Battery Mode Shutdown will be logged as an event in the event history log.
9.2.3 On Battery
On Battery signal is a Normally Open (NO) dry contact. When the UPS is supplying output power
from the battery this dry contact will be closed.
9.2.4 Low Battery
Low Battery signal is a Normally Open (NO) dry contact. When the UPS is supplying output power
from the battery and has reached the Low Battery Warning time selected in the configuration
program, this dry contact will be closed.
