backside of the flange surface on the top
of the side panel.
Starting from the bottom, mount insulation
sheet to the “L” bend section on the

Position the chamfered section of plate1
so that it faces the fan side (the left side of
the drawing) and mount it using screw .
Install M-NET board (with insulation
sheets and supports) on the four corners of
plate1 so that the rotary switches (SW11,
SW12) are on the terminal block side and
then mount.
Note: Push it firmly until you hear it “click”.
Use terminal screw to secure terminal
block .
Note:
Terminal block has a round boss for
