Load Shedding Mode - LEGRAND Raritan PX3TS User Manual

Load Shedding Mode

When a UPS supplying power to PX3TS switches into battery backup operation,
it may be desirable to switch off non-critical outlets to conserve UPS battery
life. This feature is known as load shedding.
Outlets that are turned off when load shedding is activated are called
non-critical outlets. Outlets that are not affected by load shedding are called
critical outlets. By default, all outlets are critical. To set non-critical ones, see
Setting Non-Critical Outlets
When load shedding is activated, the PX3TS turns off all non-critical outlets.
When load shedding is deactivated, the PX3TS turns back on all non-critical
outlets that were ON before entering the load shedding mode.
Exception: If you once manually perform switch-off operation on any
non-critical outlets during the load shedding mode, those outlets will NOT be
turned back on when exiting the load shedding mode.
Activation of load shedding can be accomplished using the web interface,
SNMP or CLI, or triggered by the contact closure sensors.
Tip: It is better to check non-critical outlets prior to manually entering the load
shedding mode. The non-critical information can be retrieved from the Outlets
page. See Outlets (on page 220) or
Page (on page 224).
You must have the following two permissions to perform the load shedding
commands.
•
'Change Pdu, Inlet, Outlet & Overcurrent Protector Configuration'
•
'Switch Outlet' permission for all non-critical outlets
To enter the load shedding mode:
1. On the Outlets page, click
Note: In case PX3TS prevents you from performing this command, check
your permissions, especially whether you have the Switch Outlet permission
for ALL non-critical outlets.
2. Click Activate on the confirmation message.
In the load shedding mode:
▪
You CANNOT power on any "non-critical" outlets.
▪
The lock icon
automatically powered on when deactivating the load shedding mode.
▪

WILL NOT be automatically powered on when deactivating the load
