1) Max. number of inverters are 100. If GSM modem is used for portal upload, the amount of inverters in a
network is limited to 50.
2) For outdoor use, we recommend outdoor burial type cable (if buried in the ground) for both Ethernet
and RS485.
3) Third input is used for compensation of the irradiation sensor.
4) The number of inverters to be connected in the RS485 network depend on which peripheral device is
connected.
To ensure fulfilment of IP enclosure rating, correctly mounted cable glands are es-
sential for all peripheral cables.
To ensure EMC compliance, shielded cables must be applied for sensor inputs and
RS485 communication. Unshielded cables may be applied for alarm outputs.
Other auxiliary cables must pass through the designated EMC cable clamps to es-
tablish mechanical fixing and in case of shielded cable termination to the shielding
device.
