2. Safety
2.1. General safety instructions
2.1.1. Qualified personnel
Only qualified personnel are authorised to perform any planning, installation or maintenance work, and this must be done
in accordance with the relevant instructions. The personnel must be trained for the job and must be familiar with the
installation, assembly, commissioning and operation of the product.
2.1.2. Format of the safety instructions
The safety instructions contained in this operating manual are presented in a standardised format.
They comprise a danger signal word + instruction text. The danger symbol indicates the type of dan ger, the
signal word specifies the severity of the danger, and the instruction text describes the danger and explains how to avoid it.

2.2. 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 braking
operations. They must not be used as working brakes.
•
If the brake air gap exceeds the permissible value, the braking torque may be significantly reduced.
•
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.
