3.6.3 RS485 bus
The inverter communicates with other devices via an RS485 bus. The following applies:
The inverter has two RS485 interfaces (RJ45 sockets) on the lower side of the casing.
n
The beginning and end of the RS485 bus must be terminated; see
n
Standard RJ45 cables can be used as bus cables (Cat-5 patch cables, not supplied). Use an alter-
n
native data connection cable for longer connections; see
The inverters connected to the RS485 bus operate as bus slave units.
n
The following inverters have compatible data interfaces and can be connected to the RS485 bus
as slaves:

Observe the manuals of these devices concerning the definition of addresses, termination and
permissible data cables.
If one of the optionally available devices below is connected to the bus, then this device oper-
n
ates as a bus master.
Only 1 master may be connected to the RS485 bus at any given time.
n
optionally available devices support the transfer protocol used by the inverter:
