552 Installation of communication cables
To ensure the operational safety of the inverter, the cables have to be installed in the
inverter as described in this section of the instructions. The left-hand contact protection
covers the cables and connections with dangerously high voltages (> 50 V).
In order to ensure that the inverter remains sealed, the unused apertures in the cable
glands must be closed with the locking pins (example see Figure 20 / Pos. 2). The locking
pins are included in the delivery package.
553 Network connections
The inverter can be connected to Ethernet and RS485 networks.
Note
You will find further details about data communication in the technical infor-
mation "MaxComm network". You can download this document from our web-
site at: www.solarmax.com; Downloads/Data Communication/MaxComm.
