Frequently Asked Question
UPSs are not equipped with real time clock, therefore once the "power on" was scheduled in SNMP, it requires the UPS to run continuously in standby mode to control countdown until desired time. The UPS will require input power for standby mode.
To overcome this inconvenience we suggest following setup:
Schedule Power Off in the SNMP Card at 20:00
Schedule Power On in the SNMP Card at 20:15
Schedule Input Voltage Shutdown at 20:10
Schedule Input Voltage Restore at 6:00
With this setup UPS will shutdown the loads at 20:00, it will notice input voltage failure at 20:10 and run in battery mode for 5 minutes, until 20:15. Since the loads are off and input absent, it will automatically shutdown completely. At 6:00 UPS will notice input return and power up automatically including the loads, since its due time to power up has passed.
