2.5 Electromagnetic elds when operating electrical power
engineering installations
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.
2.6 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 lm
– Plastic parts
– Insulating table supports
– Clothing made of synthetic bers
• Always place the modules on conductive and grounded surfaces.
• Always pack, store and transport electronic modules or components in conductive
packaging, such as:
– Metallized plastic or metal containers
– Conductive foam material
– Domestic aluminum foil
