14 Operating Instructions, 06/2018, A5E44455710A
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
Hearing damage when operating three-phase motors
If the permissible sound pressure level is exceeded, hearing damage can occur when
operating three-phase motors at their rated power.
Observe the maximum permissible sound pressure level according to the ISO 1680
standard. The maximum permissible sound pressure level is 70 dB (A).
Interference to electronic devices caused by electrical power equipment
Electrical power equipment generate electric fields 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.
● It is forbidden for people with pacemakers to enter the vicinity of the machine.
● 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.
● Observe the nationally applicable health and safety regulations.
● Do not carry any magnetic or electronic data media.
Electrical systems in hazardous zones must be assembled, installed, and operated by the
applicable responsible persons in accordance with the applicable rules and regulations.
Note
The basic requirements relating to electrical systems and their operation in hazardous areas
are described, for instance, in EU Directive 1999/92/EC as well as in IEC
/ EN 60079-14.
