4: Operation
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: When the UPS is under normal operation, pressing the two
ON/OFF
simultaneously will immediately
shutdown the UPS. In a single module installation this will disconnect the UPS from the load. In a parallel
module system the UPS module will shutdown and the module will effectively be removed from the parallel
load bus; however, the load may or may-not transfer to the bypass supply in the remaining modules
depending on the available module redundancy. To shut down all the modules in a parallel system you must
press both
ON/OFF
buttons on every UPS cabinet!
LOAD OFF in a PowerWAVE 9000 DPA Single module system
If, for security or emergency reasons, it is necessary to immediately disconnect the load from the UPS, press
the two red ON/OFF Buttons simultaneously. The simultaneous action of both buttons is necessary to avoid
any accidental manipulation.
LOAD OFF in a PowerWAVE 9000 DPA Parallel module system
If, for security or emergency reasons, it is necessary to immediately disconnect the load from the UPS in a
multi-module system, the two ON/OFF buttons must be pressed simultaneously on one module and then
action repeated on all remaining modules sequentially.
4.3 Description of the LCD
4.3.1 Status screens
Note: The ‘Unit’ number on the right hand side of the LCD indicates the cabinet number (in a multi-cabinet
system) together with the UPS module (slot) number within the cabinet. The maximum number of Module
units is 10 and the module slot number can vary from 1 to 5. The definition of a Module’s position is achieved
in the menu Service Set-Up.
For example:
Unit:05/3
indicates UPS module number 3 in system Cabinet number 5.
CAUTION: If the
ON/OFF
buttons are operated while the UPS is not in Maintenance Bypass it
will interrupt the load power supply.
