5 - Installation
If a single inverter is connected to the monitoring system, activate the
termination resistance of the communication line by switching switch a10
(to ON position).
Set a different RS485 address on each inverter of the chain.
No inverter
should have “Auto” as its address
. An address can be chosen freely
from out of 2 to 63.
The address on the inverter is set through the display and the push-
button panel (see relevant chapter).
We recommend not exceeding a length of 1000m for the communication line.
No more than 62 inverters can be connected to the same RS485 line.
When using an RS-485 connection, if one or more inverters are added
later to the system, you must remember to return to OFF position the
switch of the termination resistance used of the inverter that was previ-
ously the last one of the system.
Each inverter is dispatched with two (2) as the predefined RS485 ad
-
dress and with switch for setting termination resistance a10 to OFF posi-
tion.
C
onfigurable relay connection
The inverter is equipped with a multifunction
relay with configurable acti
-
vation. It can be connected with normally open contact (being connected
between the NO terminal and the common contact C) and with normally
closed contact (being connected between the NC terminal and the com-
mon contact C).
Different types of devices (light, sound, etc.) can be connected to the
relay, provided they comply with the following requirements:
Alternating current
Maximum Voltage: 240 V AC
Maximum Current: 1 A
Direct current
Maximum Voltage: 30 V DC
Maximum Current: 0.8 A
Cable requirements
External diameter: from 5 to 17 mm
Conductor cross-section: from 0.14 to 1.5 mm

This contact can be used in different operating configurations that can be
selected by accessing the “SETTINGS → Alarms” menu.
The selectable
modes are described in the paragraph on the “Settings Menu”
