CENTURION SYSTEMS SDO4 SMART Installation Manual page 25

SECTION 6
Level the SDO4 SMART again, and
measure the length needed from
the ceiling to the underside of the
drive rail, marked as 'Value Xmm' in
Figure 29.
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 bolts, and locate the
two lengths of punched angle iron
into position as shown in Figure 31.
Secure them in position with the two
drive rail hanger nuts.
Ensure that the punched
angle iron does not
protrude further than
the SDO4 SMART drive
rail base, as this will
interfere with the
operation of the motor!
