2.3. Safety precautions
• Check the proper functioning of the motor and the brake after installing the machine.
• Repairs may only be carried out by the manufacturer or an authorised repair agency. Unauthorised opening
and tampering may result in injuries to persons and property.
• The machines are not designed for direct connection to the three-phase system but are to be operated via an
electronic frequency inverter. Direct connection to the mains may damage the motor beyond repair.
• High surface temperatures may occur on the external parts of the machine. Therefore, no temperature-sensi -
tive parts may be in contact with these parts or attached to them. Protection against accidental contact
should be provided, if required.
• The EU type-examined fail-safe brakes provided are designed only for a limited number of emergency brak-
ing operations. They must not be used as working brakes.
• If the motor is not energised, no torque is produced. This may result in uncontrolled acceleration of the lift, if
the brakes are released. Therefore, the motor winding should be short-circuited to produce a speed-depen -
dent braking torque while the motor is not supplied with current. (Use the main contacts for short-circuiting
as rated motor current may be flowing.) The motor must never be short-circuited while it is energised.
• High voltages are present at the terminal connections during the operation of synchronous motors.
