HYD 5/6/8/10/15/20KTL-3PH USER MANUAL
5.10.2 RS485
For the monitoring and control of several inverters, you connect
the RS485 wires in daisy-chain.
At the first and the last inverters, you need to terminate the bus
with an 120 Ohm resistor between Pin 1 and 4.

5.10.3 Smart meter
The integrated energy management functions integrated of the
HYD 5/6/8/10/15/20KTL-3PH require to measure the power flow
at the point of grid interconnection. There are different system
configurations possible.It can be measured using smart meter
with CTs, or using directly connected smart meter.
Please refer to below table for the PIN assignments for the
RS485 connection between the inverter and the smart meter.
