Templates to facilitate instrument and keypad installation are
provided in Section 11 of this handbook.
The necessary mounting surface thickness for the different instrument
and keypad types, are summarized in Table 1-1 .
The maximum thicknesses given in Table 1-1 apply when using the
standard fixing studs supplied with your ST290 product. If you want to
install an ST290 product in a mounting surface thicker than the
maximum quoted thickness, use an M4 stud x 0.7 mm pitch, of the
appropriate length.
