Eaton Electrical 34003991EN/EB Controlled outlets, Load shedding or sequential shutdown

5.1.2 Controlled outlets

Certain UPS models are equipped with controlled outlets (generally 2) which are always dependant on the UPS's main outlet.

Shutdown of the main outlet systematically causes shutdown of the programmable outlets.

The following notations are used to identify these outlets:

◗	Main outlet:	Main
◗	Controlled outlet 1	1
◗	Controlled outlet 2	2

Utility failure	Start shutdown	Start shutdown main		Utility restore

5.1.3 Protection of a server connected to a controlled outlet

Network Shutdown Modules (NSM) starting with version 3.0 are compatible with the controlled outlets.

After connecting the server electrically to one of the controlled outlets, the NSM must be informed of the outlet number to which it is connected.

Refer to the documentation of the NSM available on the internet site www.mgeops.com section “ Downloads – Software Download.

5.1.3.1 Load shedding or sequential shutdown

It is possible to optimise backup time by shutting down non-priority equipment or sequencing the shutdown of several devices.

Two shutdown criteria are possible:

◗Shutdown of outlets after a set battery back-up time (After)

◗Shutdown of outlets at a given battery discharge level (if battery capacity under)

It is possible to specify values for both criteria. The first criterion reached will initiate server shutdown.
