5 - Installation
+ 5V output connection
On the communication and control signal terminal block
40
there is
auxiliary voltage of +5V.
The maximum absorption permitted from this auxiliary power supply
voltage is 100 mA.
C onnection of RS485 LOGGER serial communication line
The RS485 LOGGER serial communication line on the communication
and control signal terminal block
40
is reserved for the connection of
the inverter to monitoring devices that communicate with the Modbus
communication protocol. On the communication and control signal
terminal block
40
there are two connection points for each serial line
signal (+T/R, -T/R and RTN) so as to be able to make a daisy-chain
connection (“in-out”) of multiple inverters.
