1-A CONNECTION DIAGRAM
1-A - The communication terminals (RS485) are located at the bottom of the inverter. And there are two
connection terminals on the configuration circuit board: +- terminal blocks.
Connection steps
•
Please unscrew the RS485 terminal
•
Please make the connections from the Terminal Block to TrackSo
IoT Gateway
•
Connect RS485 + to Pin 3 on TrackSo ( RS485+)
•
Connect RS485 - to Pin 4 on TrackSo ( RS485-)
CONFIGURATION AT THE INVERTER END
SETTING THE BAUD RATE
The communication baud rate is to be set at 9600 bit/s
SETTING THE INVERTER ID
The inverter ID is used to identify the inverter in a RS485 connection. Set Id of the Inverter to
1
In case of multiple inverters start assigning Continuous numbering starting with 1, 2, 3, 4 …. (Range: 1 to 247)
SETTING THE DATE & TIME
For a precise calculation of the statistics in the inverter itself and in a monitoring system, date and time have
to be correct.
