Working On Machines With Permanent Magnets - Siemens 1PH818 Operating Instructions & Installation Instructions

Safety information

2.5 Working on machines with permanent magnets

Noise emissions
During operation, the machine's noise emission levels can exceed those permitted at the
workplace, which can cause hearing damage.
Take steps to reduce noise, such as introducing covers and protective insulation or adopting
hearing protection measures, so that the machine can be operated safely within your system.
2.5 Working on machines with permanent magnets
On machines with permanent magnets, the magnetic field is guided in an assembled state in
the magnetic circuit of the machine. This means that no magnetic fields, which may be to your
health, are detectable outside the machine.
Strong magnetic field when the machine is open
A strong magnetic field is always present inside the machine. If the housing is open, e.g.
when maintenance openings are open or when working inside the machine, magnetic objects
can be suddenly attracted by this magnetic field. This can result in death, severe injury or
material damage.
Working in the vicinity of the rotor is only permitted in exceptional circumstances.
Unambiguous access rules must be established in accordance with the magnetic fields
prevailing in the workplace. Clearly mark the boundaries of the areas where standing is
permitted.
People who need to use electronic or magnetic medical aids such as pacemakers, hearing
aids, implants or similar devices, are at particularly high risk. Such persons must undergo an
industrial medicine assessment.
Observe the following measures.
