6. Select the best location for mounting
Be aware that SM-200 and SM-300 have different mounting styles and each follows a separate set of
installation instructions. SM-200 is designed to stand on top of a strong surface (Figure 5); SM-300 is
intended to be installed into a sturdy panel (Figure 6).
The surface/panel you select should have the appropriate strength to hold the unit firmly in place
after installation. Apart from the strength, consider the effects of shock, vibration, shear pressure and
movement in different directions have on the mounting surface/panel. If the surface is not sturdy
enough, the housing may be dislocated from its original position and it may be damaged. If you are
uncertain about the location of your choice, contact the local dealer for advice.
