• The following thresholds at the DC input of the inverter must not be exceeded:
Use of Y adaptors for the parallel connection of strings
Y adaptors must not be visible or freely accessible in close proximity to the inverter.
• The DC electric circuit must not be interrupted by Y adaptors.
• Observe the procedure for disconnecting the inverter (see Section 9 "Disconnecting the
Inverter from Voltage Sources", page 63).

Risk of fire as a result of overcurrent on the string input
Destruction of the inverter
Since the electronic string fuse shorts the PV array in the event of a fault, the thresholds for the
maximum short-circuit current per string input given in the table above must not be exceeded.
If a string input is overloaded, it can result in an electric arc and hence a risk of fire.
• Make sure that the thresholds specified in the table above are not exceeded.
• Check whether the short-circuit currents of the connected PV modules are in compliance with
the thresholds given in the table above.
