2] Measure the length (L) between the inner edge of the drive head and the rim

of the drive wheel.

2.1.3.Preparing the tube

1] Cut the winding tube to the required length, depending on the motorised

product.

2] Deburr the winding tube and remove the swarf.

3] For winding tubes which are smooth inside, cut a notch with the following

measurements: l = 7 mm, L = 10 mm.

2.1.4.Assembling the drive-tube

1] Slide the drive into the winding tube. For winding tubes with a smooth

interior, position the cut notch on the crown.

2] The drive wheel must be locked in place to prevent any movement in the

winding tube: This can be achieved by fastening the winding tube to the drive

wheel using 4 self-tapping screws, Ø 5 mm, or 4 steel pop rivets, Ø 4.8 mm,

placed between 5 mm and 15 mm from the outer edge of the drive wheel,

regardless of the winding tube.

CAUTION

The screws or pop rivets must only be fastened onto the drive wheel and not on the drive.

2.1.5.Installing the drive-tube assembly

CAUTION

• The motorised product must not be compressed between the brackets.

• Do not use the plastic cross without the metal bracket adapter.

The drive can be fixed directly onto the drive bracket (the screw holes are spaced

29 mm apart). Use 2 screws 4 x 8 mm delivered with the motor. A manual tightening

torque of 1.5 N·m is recommended.

Drive plates are also available in the current catalogue (Select the correct drive plate

adapted to the bracket and check the torque requirements in the system). Use the 2

screws 3 x 6 mm delivered with the motor plate. A manual tightening torque of

0.6 N·m is recommended.

1] Screw the bracket adapter to the drive head.

2] Install and fix the drive-tube assembly onto the end bracket (c) and onto the

drive bracket (d).

CAUTION

• Ensure that the drive-tube assembly is secured onto the end bracket. This operation prevents the tube-drive

assembly from coming out of the end bracket attachment.

• Light gap reduced: Do not pinch cables or be careful they are not in contact with moving parts.

• Do not let the drive-tube hanged by only one side.
