Run Period

Press the RIGHT button to gain access to this menu. This menu allows selection of how long the UPS
will provide output (without mains power), in 10 minute intervals. The setting can be from 0 minutes
through to a maximum of 600 minutes (10 hours) or ‘ALWAYS ON’ using the UP/DOWN buttons. In the
‘ALWAYS ON’ mode the timer is deactivated and the UPS will continue to run until the battery low
voltage is reached and the UPS shuts down. The run time is only active while UPS is running from
Battery. If the UPS is stopped because it has exceeded the run time or low battery voltage and the mains
power is returned, the UPS will start and remain running with the run time counter disabled. The UPS
cannot be started while the “RESET LED” is flashing (this only happens when UPS is stopped by
pressing the keypad Stop button). This means it is in lock mode and needs to be reset by pressing the
keypad Reset button before any start command can be given. Default setting is ‘ALWAYS ON’.
