Electromagnetic Fields When Operating Electrical Power Engineering Installations; Electrical Voltages Are Induced When The Rotor Is Rotated; Electrostatic Sensitive Devices - Siemens SIMOTICS DP Operating Instructions Manual

2.6 Electromagnetic fields when operating electrical power
engineering installations
Electrical power equipment generate electromagnetic 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.
• 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.
• It is forbidden for people with pacemakers to be close to the machine.
• Do not carry any magnetic or electronic data media.
2.7

Electrical voltages are induced when the rotor is rotated

Danger due to induced voltages
Electrical voltages are induced in the stator when rotating the rotor. Touching the stator
connections can result in death or severe injury.
• Before starting any work at the machine, carefully ensure that the system is secured to
prevent the rotor accidentally turning in compliance with the regulations.
• If you must rotate the rotor, then ensure that each phase is grounded.

Electrostatic sensitive devices

Material damage due to electrostatic discharge
Electronic modules contain components that can be destroyed by electrostatic discharge. These
components can be damaged or destroyed if they are not handled correctly. To protect
equipment against damage, follow the instructions given below.
• Only touch electronic modules if you absolutely have to work on them.
• The body of the person concerned must have been electrostatically discharged and
grounded immediately before any electronic modules are touched.
• Electronic modules should not be brought into contact with electrically insulating materials,
such as:
– Plastic film
– Plastic parts
– Insulating table supports
– Clothing made of synthetic fibers
