Remote control connection

13

The connection and disconnection of the inverter to and from the grid can be controlled through an external control.

The function must be enabled in the relevant menu. If the Remote control function is disabled, the switching on of the inverter is dictated by the presence of the normal parameters that allow the inverter to connect to the grid. If the Remote control function is operating, besides being dictated by the presence of the normal parameters that allow the inverter to connect to the grid, the switching ON of the inverter also depends on the state of the R+ terminal compared to the R- terminal present on the connector 13 .

When the R+ signal is brought to the same potential as the R- signal (i.e. by making a short circuit between the two terminals of the connector), this causes the inverter to disconnect from the grid. The remote control OFF condition is shown on the display.

The connections of this control are made between the “R+” input and “R-”. Since this is a digital input, there are no requirements to be observed as regards cable cross-section (it only needs to comply with the sizing requirement for passing cables through the cable glands and the terminal connector).

Configurable Relay connection (ALARM)

The inverter is equipped with a multifunction relay with configurable activation. It can be connected with normally open contact (being connected between the N.O. terminal and the common contact C.) and with normally closed contact (being connected between the N.C. terminal and the common contact C.).

Different types of devices (light, sound, etc.) can be connected to the relay, provided they comply with the following requirements:

Relay Ratings

Maximum Voltage: 230 Vac Maximum Current: 1 A

Cable requirements

External diameter: from 5 to 17 mm Conductor cross-section: from 0.08 to 2.5 mm2

This contact can be used in different operating configurations that can be selected by accessing the "SETTINGS → Alarms" menu.
