9.2.2 Battery Mode Shutdown
Battery Mode Shutdown permits shutting down the UPS by turning off the rectifier, inverter, and static switch so that
there is no power to the load when the UPS is On Battery. The auxiliary power for the UPS will still be active. Activation of
the Battery Mode Shutdown will be logged as an event in the event history log.
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 and mounted at a
remote location.
NOTES:
•
remote Power Off will be performed by nO contact.
•
The current limited source for the opto coupler (+12 V dc, 50 mA) will be available from the UPS.
•
The connection to the UPS for remote connection will be via terminal block connector.
•
Battery Mode Shutdown wiring must conform to all national, regional, and local wiring codes and laws.
•
This signal must last for 1.5 seconds or longer.
•
A Battery Shutdown signal will not cause an immediate shutdown. it will start a 2-minute shutdown timer. This
timer cannot be stopped once triggered. if the mains power returns during this countdown, the UPS will still shut
down and must remain shut down for 10 seconds. Whether the UPS turns back on when the power is restored
depends on the Auto restart setting.
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.
The dry contact rated values for the On Battery and Low Battery signals are:
•
rated voltage: 5 V dc; rated current: 30 mA
•
Working voltage range: 4.5–10 V dc
