NOTE
If using a cable longer than 10 m / 33 ft in areas where there is a risk of
induced voltage surges by lightning, it is recommend to use external surge
protection devices. For details refer to:
http://www.solaredge.us/files/pdfs/lightning_surge_protection.pdf. I f
grounded metal conduits are used for routing the communication wires,
there is no need for a lightning protection device.
NOTE
An additional RS485 port (RS485-E) is available from SolarEdge, allowing
configuration of multiple RS485 buses for communications in large sites; Refer to
http://www.solaredge.us/files/pdfs/RS485_expansion_kit_installation_guide.pdf).
The following sections describe how to physically connect the RS485 bus and how to configure the bus.
To connect the RS485 communication bus:
1. Remove the inverter cover as described in Removing the Inverter Cover on page 44.
2. Remove the seal from one of the openings in communication gland and insert the wire through the
opening.
3. Pull out the R S485 terminal block connector, as shown below:
