Get a flat screwdriver of the correct
size for the clamp screws (with a tip of
approx. 3.5 mm). Make the following
connections, loosening the screw,
inserting
the cable/s and then
tightening the screw again (maximum
torque 0.5 N/m).
Do not tighten the screws with force
to a torque of more than 0.5N/m to
avoid damaging the clamp.

The X20 and X27 clamps are dedicated to
the communication connection (Table 11-2).
Clamps from X1 to X6 are dedicated to the
state of the 55kWp modules (Table 11-3).
Clamps X10 and X11 are connections for
switching on / off via an external command
(Table 11-4).
In Figure 11-11, on the left, is also
indicated the composition of a single

are through connections.
