Attach the fuse cover (PCOVP6637RCZZ) to a fuse of 1.5A.
3
Cut the both ends of the I/F PWB CN2 11 pin cable (brown) at
about 1mm or less from the connector using a nipper.
2) Clean and remove oil from the sheet attaching section of the PWB
mounting angle (LANGT7480RCZA) with alcohol. Fit the angle
hole with the hole in the PWB protection sheet (PSHEP
