In the Load segment #1 restart delay (sec) field, enter the number of seconds after the UPS restarts that
the UPS should wait before restarting load segment #1 (from 0 to 99999 seconds, 30 seconds by

Configuring the shutdown parameters
Follow these shutdown principles when configuring the shutdown parameters:
•
The Shutdown initiated after value entered for the HPPP Administrator must be equal to or greater than
the HPPP Client configured with the greatest Shutdown initiated after value. Otherwise, the Client starts
to shut down at the same time as the HPPP Administrator.
