Setup screens

From the Setup screen, you can select the following items:

Shutdown

Defaults

Output Frequency

Alarms

Bypass

Copy

Other

Conﬁgure the following system shutdown conditions:

Low Batt Dur: Low battery duration is the time from low battery signal to the

shutdown of the load. This signal is sent to the server using shutdown software

(PC + PCNS).

Shutdwn Dly: Shutdown delay is the time from when the UPS receives a

shutdown command (usually sent by a server) to the shutdown of UPS power to

the load equipment. This delay allows load equipment time to ﬁnish shutdown

processes.

Return Dly: Return delay is the amount of time the UPS wants to turn on after a

power outage has ended.

Return Bat Cap: Return battery capacity is the minimum percentage of battery

capacity required for the UPS to turn the load on.

Return all UPS settings to their default values.

Set the desired output frequency

Redundancy: The state of redundancy that will trigger an alarm. Choices are:

• N+0 – an alarm will occur only when there is more load than all functioning

power modules can support;

• N+1 – an alarm will occur when there are no spare power modules in good

condition;

• N+2 – an alarm will occur when there is only one functioning power module.

Load: When the load is greater than this threshold, an alarm will sound.

Runtime: When the time the UPS can power the load is less than this threshold,

an alarm will sound. This alarm is the result of an increase in load or a decrease in

battery capacity.

Set the conditions in which the UPS will automatically go into bypass operation.

Copy the UPS settings.

Self Test: Set the UPS to perform a self-test automatically at periodic intervals.

USP ID: Provide a unique name for the UPS.

Vout Reporting: Set the reporting to the number of the tap to which the most

signiﬁcant load is wired on the output transformer.

Output: Set the UPS output voltage.

BatFrAmpHour: Set the Ampere-Hour rating of external battery enclosures that

are not APC Symmetra PX Battery Enclosures.
