CENTURION SYSTEMS SDO4 SMART Installation Manual page 26

SECTION 6
Use a spirit level to ensure that
the SDO4 SMART is still level and
parallel to the ceiling. Align the holes
of the punched angle iron mounted
to the ceiling, with the holes on
the punched angle iron mounted
to the drive rail hanger. Secure it
into position using two supplied M8
flange bolts and nuts using a 13mm
socket.
Using a spirit level, ensure
that the SDO4 SMART is
level on both the X-Axis
and Z-Axis of the horizontal
plain. If it is not, it may
cause the motor to stress,
or the drive rail to twist.
