Trouble Shooting - Eaton 9EEBM240 User Manual

Each 9E UPS ships with Eaton Intelligent Power Software suite. To begin
installing, see the instructions accompanying the Software suite CD.
Eaton Software suite provides up-to-date graphics of UPS power and
system data and power flow.
It also gives you a complete record of critical power events, and it notifies
you of important UPS or power

If there is a power outage and the 9E UPS battery power becomes low,
Eaton Software suite can automatically shut down your computer system to
protect your data before the UPS shutdown occurs.
