BASIC JOB AND SAFETY
All preparatory operations, assembly and electrical connections must be carried out by
technical and specialized personnel to guarantee best performances and good function
of the MR28-B tubular gear motor. First of all, please check that the following
fundamental assumptions have been satisfied:
Check that the electrical supply used corresponds to the
“TECHNICAL DATA” label attached to the machine and that the given
temperature range is compatible with the place of installation.
Gear motor performances must be sufficient to move the curtain; any limits
indicated in the technical data
(page 5).
Ensure the gear motor has not been damaged during transport, first visually
and then by working it in both directions.
Check that the inner section of the window length is over 270 mm in length.
Anything shorter than this will not allow for assembly of the gear motor.
Before mounting gear motor into position, ensure supports have been adequately
prepared. These operations must be carried out “at the bench” with the help of
minimum equipment.
6.1. Blind support tube and end cap
CAUTION: the blind support tube must have an internal diameter of 26 mm.
After cutting the blind support tube to the desired length, which depends on the width of
the window, the tube must be cleaned of all burr caused by the cutting; it
recommended that a deburring knife be used to round the internal edges in order to
facilitate insertion of the support end caps.
6.2. Gear motor
Insert the gear motor into the tube until it reaches the stop of the sliding bush.

Use a conical tool to make a small flare at 90° which will contain the head of the
screw.
Take the M3x8 countersunk head screws provided and screw them into the two
holes. The holes do not require tapping since these are self-tapping screws.
Fix each screw until the head disappears completely.
Caution. If the head of the screw protrudes from the windup tube, the depth of
the flare must be increased accordingly. Any protrusion of the screw from the
tube may damage the fabric being wound up around the roller.
6.3. Assembly of the supports
Follow the steps below.
Carefully select the position at which to fix the supports. Horizontal fixing uses the
holes in line with the tube, whereas orthogonal fixing uses the holes located at 90°
on the bracket.
The support bracket with the cross slots should be positioned near the motor, i.e.,
where the power supply cable comes out.
Take the plastic bush with Ø4 hole that can be found in the bag of small metal parts
and assemble it in the hole of the other bracket; this requires a certain amount of
pressure so an appropriate tool should be used.
Mark the positions of the holes with a pencil.
Depending on the type of support
(wall, frame or other),
use a drill bit to drill a hole
with the selected diameter in the points marked previously with the pencil.
Screw in the screws without tightening them and check the linearity and orientation
of the brackets.
6.4. Assembly of motorization
Insert opposite motor cover pin in opening provided on bracket.
Insert protruding tongue of motor head into cross threading slot and position in
alignment with curtain.
Check that wrapping tube is horizontal. Should this not be the case, loosen fixing
screws and reset properly. Remember that even a slight inclination of the mounting
means that the curtain is not aligned and will produce waves in the fabric.
Fix bracket screws permanently into position.
7. Electrical connections
The cable furnished with the MR28-B tubular gear motor is 2 m long and has been
calculated in accordance with safety rules. In the event that the distance between the
gear motor and feeder should exceed this length, the cable should be extended.
See table on page 6 for conductor section indications.
After connecting electricity supply to feeder, check that up key function opens the
curtain and down key function closes it. In the event that keys function to the contrary,
invert cable positions.
For harness, please follow the diagram indicated on this page.
