Note:

The RS485 communication bus must be terminated at both cable ends.

Note:

The two network types cannot be mixed. The inverters can only be connected in networks

which are either solely RS485 or solely Ethernet.

Note:

Each inverter has a unique RS485 address when it is delivered. This address is defined at the

time of production.

Note:

Ethernet connection is recommended for faster communication.

RS485 connection is required when a web logger or data logger is connected to the inverter.
