I have tried my best to integrate the information on
wire diameters and lengths and the wiring system
diagrams from “Basic_Installation_Instructions_
PAW-280PAH3M_PA.docx“ in to this existing doc-
ument, but it was a hard nut for me to crack, be-
cause the information contents was so different in
the two docments (at least in my understanding).
Therefore, please check carefully if the information
in this section is a) correct and b) makes sense in
the way it is presented.
Thanks in advance for any suggestions for improve-
ment.
