5�2 Connecting the inverters via the RS485 interface
Use commercially available RJ45 network cables, also referred to as RJ45 patch cables,
for wiring the MaxComm network. We recommend using single-screened category-5
cables (CAT 5e).
DANGER!
Fatal electric shock hazard!
For connection to the network, it may be necessary to open the inverter. Com-
ponents within the inverter are charged with a high voltage. Inverters may only
be opened by a service technician.
Note
Make sure not to confuse the Ethernet and RS485 connections since other-
wise no signals can be transmitted.
