5.4.2 Connecting the DC feed line to the MCU
The connection to the DC voltage of the PV generator ensures uninterrupted operation
of the MCU in the case of a failure of the AC mains. In addition, the connection permits
measuring the DC voltage by the MCU.
Cable requirements

)
Procedure
1. Connect the cable to the terminals “DC+” and “DC−” within the MCU. Position of the
terminals, see 5.4.1 “Interior view of the MCU”.
2. Connect the cable to the fuse holders “DC+” and “DC−” within the nearest inverter.
Make sure the polarity is right. Position of the fuse holders: see 5.3.1 “Interior view of
the inverter”.
