ABB UNO-2.0-I-OUTD Product Manual page 73

Changing the above-mentioned parameters may prevent disconnection from the grid if the
new values exceed those given in the standards of the country of installation. If these para-
meters are changed to values outside the standard range, an interface protection must be
installed external to the inverter in accordance with the requirements of the country of instal-
lation.

1. Address
This section of the menu allows you to set the serial port addresses of the
individual inverters connected to the RS485 line.
The addresses that can be assigned are 2 to 63. The UP and DOWN
buttons scroll through the numerical scale.
'AUTO' selection cannot be used at present.
2. Display Set
This section of the menu allows you to set the display properties:
• Light: sets the lighting mode and adjusts the display backlight
Mode:
ON: Light always on
OFF: Light always off
Auto: Automatic backlight control. The light is switched on whenever a
button is pressed and stays on for 30 sec, after which it gradually dims
out.
Intensity: adjusts display brightness (scale from 1 to 9)
• Contrast: adjusts display contrast (scale from 1 to 9)
• Buzzer: sets button sound
ON: button sound is on
OFF: button sound is off
3. Service
This section of the menu is reserved for installers.
A special access password is required, which may be obtained from the
