10. Possible confi gurations required at start up
Below is a list of possible confi gurations that may be required at the inverter's start-up. Other confi gurations are
possible, these are not strictly related to the inverter's start-up and for them you should refer to the User Manual.
The following confi gurations can be modifi ed with the four keys on the display (Esc, Up, Down and Enter); by
pressing the Up and Down keys you go from one item to another or scroll the numerical scale, by pressing the
Esc key you return to the previous menu and by pressing the Enter key you go to the sub-menu corresponding
to the selected item or you go to the next fi gure to modify. To access the following functions, you have to open
the "Settings" item from the main menu, entering the password which is 0000 by default.
Confi guration of the RS458 port address (Address): When there are several inverters wired on the same RS485 line (ref.
Par. 7), the RS485 port address must be different for each inverter (N.B. "Auto" is not permitted as an address); to modify
the address you have to access the Address sub-menu.
Date/Time Settings (Time): On fi rst start-up of the inverter, it is necessary to confi gure the date and time by accessing
the Time sub-menu.
Language settings (Language): Should it be necessary, you can choose between the national language and English by
accessing the language sub-menu.
Start-up voltage (Vstart): The start-up voltage can be regulated by accessing the Vstart sub-menu and, in the case of
independent channel confi guration, it is possible to confi gure the Vstart for channel 1 and channel 2 separately.
Autotest function for interface protection (Autotest): The Autotest function is only on -IT models and allows the
interface protection to be tested for grid OverVoltage, UnderVoltage, OverFrequency and UnderFrequency. When the
inverter carries out the Autotest, it varies the protection thresholds until the value at which the inverter is operating
is reached and when it exceeds this value and if the protection is suffi cient, the inverter disconnects itself within a
certain time which is set by the local standard. The test result is shown on the display with an indication of the value and
the intervention time for the protection. To access this function you must open the Autotest sub-menu, selecting the
protection to be tested (OV, UV, OF, UF).
