Depending on the options installed in your Conergy WR unit, you have
the following alternatives to connect the solar inverter at the DC solar
modules and to the public AC mains:
Note! Only cables up to a cross section of 4 mm² are permitted for
the AC-plug-type connector.
Only use cables with a cross-section of 4 sq.mm for the Conergy WR
5900.
Important! We recommend AC protection as follows:
- A special16 A fuse for each Conergy WR 1700 and 3300
- A special 25 A fuse for each Conergy WR 4600 and 5900
- Alternatively for Conergy WR 4600 and 5900: 32 A , type „C“ miniature
circuit-breaker
