Connecting the Gateway

Requirements:
☐ If several Gateways are present in the system, these have to be connected to each other prior
connection to the module in the inverter.
☐ A maximum of three Gateways can be connected to one module in the inverter.
☐ A terminator must be plugged into the last gateway in the row.

Cable requirements:
☐ Number of insulated conductor pairs and insulated conductor cross-section: at least
2 x 2 x 0.22 mm² (2 x 2 x 24 AWG)
☐ The conductor must be shielded.
☐ The conductors must be twisted-pair.
☐ UV-resistant for outdoor use
☐ The conductors lengths in the inverter must be as short as possible. This prevents contact with
live conductors.
☐ If the conductor is to be installed without conduit, the conductor has to be suited for outdoor
use.
☐ If the conductor is to be installed in a conduit together with live conductors, the conductor has
to be insulated for 600 V.
