CENTURION SYSTEMS SDO4 SMART Installation Manual page 37

SECTION 6
Position the SDO4 SMART again,
as shown in Figure 57, and measure
the length needed from the ceiling
to the underside of the drive rail,
marked as 'Value Xmm' in Figure 62.
Using an angle grinder or hack saw,
cut two lengths of punched angle
iron to the measurement taken for
'Value Xmm'.
Snip off the four corners of
the punched angle iron to
add a degree of safety and
neatness to the installation.
Remove the two drive rail hanger
nuts from the gutter bolts, and
locate the two lengths of punched
angle iron into position as shown in
Figure 64. Secure them in position
with the two drive rail hanger nuts.
