Fig. 8: All DC inputs parallel for M8/M10 variant
Connection variant: DC inputs in parallel
Only 2 MPP trackers can be connected in parallel at any one time. (I. e. 1 & 2; 3 & 4; 5 & 6; 7 & 8; 9 & 10). If only one
tracker is used, the other MPP tracker must be electrically bridged (2 / 4 / 6 / 8 / 10).
All strings in parallel on both MPP trackers. Only strings with the same voltage may be connected in parallel.(U
U ).
nm
ATTENTION: In this installation all strings must be connected in parallel and selected and activated in the menu item
DC configuration.
NOTE: The maximum permissible nominal DC current doubles when both MPP trackers are installed in parallel.

4.3.2 Connecting the PV generator
Connecting the DC cable
↻ PV generator is dimensioned according to the performance characteristics of
the device.
1 Remove protective cap from the DC connection plugs required.
NOTE: For each plug connector pair, the power output can be connected in re-
lation to the string fuse size used.
2 Connect the PV generator to the DC plug connectors on the underside of the
device according to the polarity of the PV generator.
NOTE: Meet the requirements of protection class IP66 by closing the unused
plug connectors with protective caps.
» The device is connected to the PV generator.
4.4 Establishing equipotential bonding
NOTE
Depending on the local installation specifications, it may be necessary to earth the device with a second
ground connection. To this end, the threaded bolt on the underside of the device can be used.
