Key function summary
ON/OFF Start-up and shutdown buttons
The UPS may be switched ON or OFF by simultaneously pressing both ON/OFF keys on the control panel.
This is to prevent accidental UPS start-up or shutdown.
Note: Under normal operation, pressing the two ON/OFF simultaneously will immediately shutdown the UPS
module.
In a single module installation this will disconnect the UPS from the load.
In a parallel module system the UPS module will shutdown; however, the load may or may-not transfer to the
bypass supply in the remaining modules depending on the prevailing load and module redundancy.
To shut down all the modules in a parallel system you must press both
ON/OFF
buttons on every UPS
cabinet!
