Positioning the Spacers for the TD 200, TD 200C, and TD400C
The self-adhesive spacers included with the TD 200, TD 200C, and TD400C maintain the
pressure on the TD device circuit board when the TD device is assembled. The number of
spacers required is dependant upon the thickness of the mounting surface.
Refer to Figure 2-3 and use the following procedure to position the spacers:
1. Determine the number of spacers required, based on the thickness of the panel:
– For up to 1.5 mm, use one spacer.
– For 1.5 mm to 4.0 mm, use two spacers.
2. Place the spacers over the screw holes on the inside of the backplate.
