n 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 3.6.5, p.25.
n Standard RJ45 cables can be used as bus cables (Cat-5 patch cables, not supplied). Use an
alternative data connection cable for longer connections; see 3.6.4, p.24 .
n The inverters connected to the RS485 bus operate as slaves.
Note
The following inverters have compatible data interfaces and can be connected to the RS485
bus as slaves:
