4.2.1 - Cleaning
- Release the brake by hand with the brake lever, or re-
lease the brake springs and open the brake arms, and
remove the protection which is between the brake shoes
and the brake wheel of the traction sheave.
- Remove any rust-protective wax from the sheave.
Do not use any abrasive material, but rather
a cloth soaked in alcohol or solvent. Use a
solvent wich does not contain oil to avoid oil
contamination of the friction surfaces.
WARNING: only use the solvent in a ventilated area.
If the machines are delivered with a bed-plate and a
secondary sheave, the secondary sheave has to be
cleaned as well (see above).

X2 - X3 - AC Gearless
Commissioning
4.2.2 - Mechanical installation
- The gearless machine must be installed on a bed-plate
not subject to vibrations, and must be secured by four
M20 bolts,nuts, and washers. The bolts must be secured
only when ropes, car, counter-weight, traction sheave
and secondary sheave are perfectly aligned. When this
operation is completed, weld the plates attached to the U
bolts of the secondary sheave if it is supplied.
When the gearless is placed in the basement and
strenght of the ropes on the traction sheave is upward it
has to be fixed on the bedplate with two additive nuts M 20
placed on position B left and right side of the machine.
- Before installing the ropes, check that the traction
sheave can rotate freely by releasing the brake and ro-
tating the sheave by hand.
- When the ropes are installed, the two rope guards (RG)
must be screwed .
The gearless can also be placed on right or left side
fixed on the bedplate by four M 20 nuts (A, B, C, D), rope
strenght orientated downward.
4.3 - Connection
-
See connection diagrams in the terminal boxes (motor,
brake and blower if installed).
- Connect the motor using cables and connectors of an
appropriate size.
- Check also that connectors are crimped onto
the cables.
Be particularly careful when screwing on the terminal
nuts (if done incorrectly, this could damage the
connections by overheating : see figure 2).
- During installation, include safety devices to protect the
motor.
- Connect the supply cables to the terminals U1, V1, W1
as per IEC 34.1 to have clock-wise rotation of the shaft.
- If case, connect thermistors to the remote control.
- Connect the earth terminal.
