Selecting a Communication Mode

1. You can choose either the MBUS (PLC) or RS485 communication mode for the SUN2000-
29.9KTL/33KTL-A/36KTL/42KTL.
2. FE communication is optional for the SUN2000-36KTL. If you need to use the FE communication
mode, contact local technical support.
3. If the SUN2000-36KTL adopts FE communication mode, it supports only RS485 and FE
communication modes, and does not support MBUS (PLC) communication mode.
4.6 Installing RS485 Communications Cables
1. When routing communications cables, separate communications cables from power cables to
prevent communication from being affected.
2. An RS485 cable can connect to either a terminal block or an RJ45 network port. It is
recommended that the RS485 cable connect to a terminal block.
