1)
A maximum of 100 inverters can be connected in 1 network. If
GSM modem is used for portal upload, the number of inverters in a
network is limited to 50.
2) For underground use, outdoor burial type cable is recommended
for both Ethernet and RS-485.
3)
Third input is used for compensation of the irradiation sensor.
4)
The number of inverters to be connected in the RS-485 network
depends on which peripheral device is connected.
CAUTION
To ensure fulfilment of IP enclosure rating, correctly
mounted cable glands are essential for all peripheral
cables.
CAUTION
To ensure EMC compliance, shielded cables must be
applied for sensor inputs and RS-485 communication.
Unshielded cables may be applied for alarm outputs.
Other auxiliary cables must pass through the designated
EMC cable clamps to establish mechanical fixing and in
case of shielded cable termination to the shielding device.
