2 Safety instructions
2.1 Personnel responsible for safety
Operator
ƒ An operator is any natural or legal person who uses the drive system or on behalf of
whom the drive system is used.
ƒ The operator or his safety officer must ensure
– that all relevant regulations, instructions and legislation are observed.
– that only qualified personnel work with and on the drive system.
– that the personnel have the Operating Instructions available for all corresponding
operations.
– that non−qualified personnel are prohibited from working with and on the drive
system.
Skilled personnel
Skilled personnel are persons who − because of their education, experience, instructions,
and knowledge about corresponding standards and regulations, rules for the prevention
of accidents, and operating conditions − are authorised by the person responsible for the
safety of the plant to perform the required actions and who are able to recognise potential
hazards.
(See IEC 364, definition of skilled personnel)
2.2 Residual hazards
Protection of persons
ƒ The motor surfaces can become very hot. Danger of burns when touching!
– If necessary, provide protection against contact.
ƒ If the motor is inverter driven, high−frequency voltages may be capacitively
transferred to the motor housing.
– Ensure careful earthing of motor housing.
ƒ Danger through unintended starts or electric shocks
– Connections must only be made when the equipment is deenergised and the
motor is at standstill.
– Built−in brakes are not fail−safe brakes .
