UPS Module control panel
A control panel is fitted to the front of each UPS module. During normal operation the control panel can be used by the
operator to start/stop the module as part of the UPS system operating procedures, monitor the module’s operating
performance and manually transfer the load between inverter and bypass. The control panel is also used by a trained
service engineer to test and set-up the module’s operating parameters during troubleshooting and commissioning.

2.7.1 Module control panel buttons
The module control panel buttons allow you to:
• Start-up and shut-down the UPS and transfer the load between inverter and bypass.
• Monitor and display the UPS operating voltages, currents, frequencies and other values on the LCD display.
• Reset/cancel an alarm.
You can switch the UPS module on or off by simultaneously pressing both
ON/OFF
buttons (for less than 1s). The
requirement to press both buttons is intended to help prevent accidental operation.
Pressing the two
ON/OFF
buttons during normal operation will immediately shut down the UPS module. The load may or
may-not transfer to the static bypass, depending on whether or not the number of remaining on-line UPS modules satisfies
the system’s redundancy – i.e. if there is a sufficient number of modules remaining to support the system’s load then the
load is not transferred.
To shut down all the UPS modules in a parallel system you must press both ON/OFF buttons on every module.
