4.7.9 Connecting the cable for data communications
The inverters in the SolarMax S series have two RJ45 sockets for data communications
within a MaxComm network:
■ The left-hand RJ45 socket (Pos. 5 in section 4.7.2) is only a RS485 interface. The
RS485 interface is used for connections with other SolarMax inverters or accessories
with the MaxComm interface.
■ The right-hand RJ45 socket (Pos. 6 in section 4.7.2) can be used both as a RS485 and
as an Ethernet interface, the desired function can be toggled in the “Settings” menu.
The Ethernet interface is used for connecting an inverter directly to a PC or to MaxWeb
xp. However, if both sockets are con gured as RS485 interfaces, a network containing
several RS485 nodes can be set up.
Connection recommendations
If the RJ45 sockets are used and the inverter is exposed to the weather, please use prod-
ucts from the VARIOSUB-RJ45 range with IP67 protection from Phoenix Contact. This
ensures that the installation meets the requirements of IP54.
■ RJ45 connector, 8-pin, quick connector system (art. no. 1658493)

Procedure

nector plug is rmly in place.
