10.3 Closing of the Sunny Mini Central
Follow the sequence described below and all safety instructions in section
10.1 "Safety Instructions" (Page 58)!
Step Instruction
1 Secure the housing cover by evenly
tightening the two middle screws with the
corresponding washers first. The toothing of
the washers must face toward the housing
cover. The screws must be tightened with
approximately 6 Nm torque in order to
guarantee both the sealing of the housing
and the grounding of the cover. Then
tighten the four remaining screws as well.
If you should lose a screw or washer, the
Sunny Mini Central accessories kit contains
a spare screw and spare washer.
NOTICE! The grounding of the housing cover is ensured
by the toothed washers. Take care that for all six screws,
the washers are installed with the toothing against the
cover!
2 Connect the PV generator by reconnecting
the DC plug connectors of the Sunny Mini
Central with those of the strings. Close the
unused DC input sockets with the caps
included in the delivery.
3 Check the Electronic Solar Switch for wear, as described in section 12.2
"Inspection of the Electronic Solar Switch" (Page 72).
