11.5.1 System Display
The user-friendly touchscreen graphical display on the system level offers the opportunity of directly monitoring the system status as well
as the status of each individual module. The graphical display additionally provides all the measurements (module and system level) and
the user is able to transfer from INVERTER to BYPASS and vice-versa. All other commands must be performed on the DPA display. With
both displays in place (module and system level), the UPS offers full user friendliness without making compromises on robustness.
7" touchscreen display (one per cabinet)
2 x 20 character LCD display (one per module)
LED-indicator, 5x green/red LEDS (one per module)
