Noise emissions
During operation, the machine's noise emission levels can exceed those permitted at the
workplace, which can cause hearing damage.
• Ensure that nobody is in the area of increased noise emissions during machine operation.
• Take steps to reduce noise so that the machine can be operated safely within your system.
The following measures may help to reduce noise.
– Covers
– Noise insulation
– Hearing protection measures
Prevention of hearing damage
If the permissible sound pressure level is exceeded, hearing damage can occur when
operating three-phase motors at their rated power.
The permissible sound pressure level is 70dB (A).
Electromagnetic elds when operating electrical power equipment
Electrical power equipment generate electromagnetic elds during operation. Potentially
lethal malfunctions can occur in medical implants, e.g. pacemakers, in the vicinity of
electrical power equipment. Data may be lost on magnetic or electronic data carriers.
• Protect the personnel working in the plant by taking appropriate measures, such as erecting
identifying markings, safety barriers and warning signs and giving safety talks.
• Comply with all of the national health and safety regulations.
• It is forbidden for people with pacemakers to be close to the machine.
• Do not carry any magnetic or electronic data media.
2.1.5 Use in hazardous areas
Electrical installations in hazardous zones must be mounted, installed and operated by the
applicable responsible persons in accordance with the applicable rules and regulations.
Note
The basic requirements relating to electrical installations and their operation in hazardous areas
are described, for instance, in directive 1999/92/EC as well as in standard IEC / EN 60079-14 or
when using the electrical machine outside the European Community, in the country-specic
regulations.
