• If the inverter is not equipped with a DC switch-disconnector but this is mandatory in the country
of installation, install an external DC switch-disconnector.
• The following limit values at the DC input of the inverter must not be exceeded:
Maximum input voltage Maximum input current
1,000 V (DC) 36 A (DC)
No mixed connections between input areas
For instance, if the positive pole of a string is connected at input area A and the negative
pole of the same string is connected at input area B, this is called a mixed connection.
Only connect strings at 1 input area and never mix the input areas A and B!
Otherwise, the inverter no longer fulfills the requirements of the EMC Directive (Directive
on the electromagnetic compatibility of a device) and forfeits its operation licence.
