5.3.2 - Installing the motor
The Gearless motor must be installed on a chassis that is not
subject to vibration and must be secured using 4 M12 screws
class 8.8.
The permissible unevenness of the chassis is 1 mm.
Due to the mechanical construction of the motor, this is
mandatory to use the isolation pads supplied for the fixing of
the motor onto the chassis (2 rectangular pads to be installed
under the motor feet and 4 round pads to be installed under
the chassis).
4 x Screw M12 x L (not supplied)
2 x Top pads (LSY160-1-237)
4 x Bottom pad (GIR130-1-47)
The mounting principle is as follows:

The chassis must be drilled as follows:

Motor type W (mm)
E27S 150 +/- 0,5
E27M 150 +/- 0,5
E27L 170 +/- 0,5
The fixing screws (not supplied) must be tightened once the
traction ropes and the traction sheave are perfectly aligned
and once the full load is applied onto the traction sheave.
After contact of the screw’s head with the metallic washer,
tighten of 1 turn with a tolerance of 0/+¼ of turn.
For securing the fixing screws, use a thread locking glue (low
or mid strength) applied onto the 10mm of the screw end or
a mechanical seal on the screws heads (linking two screws).
Below are the recommended screw’s lengths depending on
the thickness of the chassis:
Thickness
of the chassis
6 to 8 mm 10 to 12 mm < or = 16
Screw length 50 or 55 mm 55 or 60 mm 60 or 65 mm
5.3.3 - Traction ropes
Check that the traction ropes are of correct type for the
sheave of the motor.
The rope pull must be vertical.
If the number of grooves available on the traction sheave is
higher than the number of ropes installed then the ropes must
be centered on the sheave.
Positioning of the traction ropes
The motor’s fixing screws must not be loaded with a shearing
force.
