SHUTDOWN

Eaton ConnectUPS –MS Web/SNMP Card S 164201819 Rev 3 www.eaton.com/powerquality

Load Shedding or Sequential Shutdown

You can optimize backup time by shutting down non-priority equipment or sequencing

the shutdown of several devices.

Two shutdown criteria are possible:

S Shutdown of receptacles after a set battery back-up time (After)

S Shutdown of receptacles at a given battery discharge level (if battery capacity

under)

If you specify values for both criteria, the first criterion reached initiates server

shutdown.

Sequential Startup

You can delay receptacle power-on to reduce inrush currents on startup or to

sequence the startup of several devices.

Load segment startup after a given time is based on startup of the main receptacle.

Extended Power Outage, Shutdown Initiated by the Shutdown Timer (Shutdown After)

During battery backup time, the Shutdown Timer of the ConnectUPS-MS Card is

reached. After a user-defined backup time period (see “Shutdown Parameters” on

page 31), the shutdown of all servers is initiated, followed by the UPS shutdown

(depending on its configuration). The UPS restarts when utility power is restored

(depending on its configuration).

Shutdown duration: Maximum value of shutdown times of the protection application

subscribed to the card. This value is updated each time a client subscribes or

unsubscribes. Figure 56 shows a graph of a shutdown initiated by the Shutdown

Timer.
