Using the UPS LOAD OFF Pushbutton or Command
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.
The UPSs (including Bypass) remain off until restarted.
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 7.4.28).
To use the
LOAD OFF
pushbutton:
1.

pushbutton on the UPS to shut down.
