5. Installation steps
(1) Routing the cables
(a) Wall-embedded installation using an electric box
Pull the M-NET transmission cable through the hole on the wall and the electric box, and seal
the gap between the cable and the end of the conduit tube with putty.
(b) Wall-surface installation
• To route the cable through the wall:
Drill a hole in the wall, push the M-NET transmission cable through the hole, and seal the
gap between the cable and the hole with putty.
• To route the cable along the wall surface:
It is approximately 10 cm (4 in) from the cable access hole on the back of AT-50B to the
M-NET terminal block. Trim off the excess transmission cable, if any.
(2) Attach the mounting bracket on the wall.
Attach the mounting bracket on the designated area on the wall using the supplied screws.
The pitch for the mounting bracket is shown in the figure at right.
(3) Attach the controller to the mounting bracket.
After inserting the M-NET transmission cables (A and B) through the cable access hole on the
controller from the back, hang the controller on the hooks of the mounting bracket.
Attach the controller to the mounting bracket using twenty M4 screws with spring washers/
washers.
(4) Connect the cables.
Connect the M-NET transmission cables (A and B) to the terminal block. M-NET transmission
cable is non-polarized.
Insert the cables in the groove on the controller so they will not be pinched when the cover is
installed.
*To route the cable along the wall surface
Secure the cables in place with a cable cover, and seal the gap between the cable cover and the
controller with putty.
(5) Replace the cover.
Snap the cover into place, and attach it to the controller with a screw at the bottom.
*Tighten the screw to a torque of 10 N·m or less.
