3. Lead the cable through the
cable gland. Plug the wires to
terminals A2 and B2 on the
inverter without tool
tightening.
Note:
For reconnection, press the
part as shown in the red
circle so as to pull out the
cable.
4. When the length of RS485 cable is longer than 100 m, push the 120
Ohm (2) switch to “ON” to ensure stable communication, as shown
below.
6.3 Grid Connection
Residual Current Device
With an integrated universal current-sensitive residual current monitoring unit
inside, the inverter will disconnect immediately from the mains power as soon
as a fault current with a value exceeding the limit has been detected.
However if an external residual current device (RCD) is mandatory, the switch
must be triggered at a residual current of 300 mA or higher.
Cable Requirements
Cross-section: 4 mm², cable diameter: 11 mm to 14 mm
All the AC cables should be equipped with correctly colored cables for
distinguishing. Please refer to related standards about the wiring color.
