Alarm

The inverter is equipped with an alarm system which allows for the switchover of a
relay contact (available both as a contact normally set open - N.O. - and as a contact
normally set closed– N.C.). The relay contacts are accessible from the front cover as
shown in Fig. 22. This contact can be used, for example, to activate an acoustic or
visual alarm. In any case, the contact voltage/current rating of 230V/1A must not be
exceeded.
This function can activate 4 different modes of alarm. By pressing the ENTER key,
you can access the following submenu:
The selected entry is highlighted by an arrow on the left-hand side of the display. Use
the UP/DOWN keys to change your selection and the ENTER key to confirm.

PRODUCTION: the relay is only activated when the inverter is connected to
the grid.
For example, if the N.O. (or N.C.) contact is chosen, the contact will remain open
(closed) until the inverter is connected to the grid; once the inverter is connected and
begins to transfer power, the relay will switch its status to closed (open). When the
inverter disconnects itself from the grid, the relay contact returns to its rest position,
i.e. open (closed).
