A UPS Load Off is initiated by the
LOAD OFF
pushbutton from the main menu bar, the Load Off command on
the UPS Control Command screen, or the Load Off command on the Bypass Control Command screen. The
UPS
LOAD OFF
controls the UPSs' outputs by powering down the UPS and de–energizing the critical load.
NOTE
The UPS Load Off controls each UPS independently and does not shut down the whole
distributed bypass system unless all UPSs have been transferred to bypass. To
immediately shut down the whole system, use the REPO switch (see paragraph
Using the Remote Emergency Power-off Switch

pushbutton on the UPS to shut down.
The Load Off screen is displayed, providing a choice to proceed or abort the shutdown.

feature only when you want to de–energize the critical load.

To shut down the UPS, press
LOAD OFF
from the Load Off menu bar, and hold for three seconds. To
abort the shutdown, press
CANCEL
.
When LOAD OFF pushbutton is selected and held for three seconds, the input, output, battery, and
bypass backfeed contactors open, and the power module is turned off on the UPS.

Do not attempt to restart the system after Load Off until the cause of the shutdown has been identified and
cleared.
