Safety instructions for electromagnetic fields (EMF) 
 
Danger to life from electromagnetic fields 
Electromagnetic fields (EMF) are generated by the operation of electrical power equipment 
such as transformers, converters or motors. 
People with pacemakers or implants are at a special risk in the immediate vicinity of these 
devices/systems. 
•  Ensure that the persons involved are the necessary distance away (minimum 2 m). 
 
Handling electrostatic sensitive devices (ESD) 
Electrostatic sensitive devices (ESD) are individual components, integrated circuits, modules 
or devices that may be damaged by either electric fields or electrostatic discharge. 
 
 
Damage through electric fields or electrostatic discharge 
Electric fields or electrostatic discharge can cause malfunctions through damaged 
individual components, integrated circuits, modules or devices. 
•  Only pack, store, transport and send electronic components, modules or devices in their 
original packaging or in other suitable materials, e.g conductive foam rubber of 
aluminum foil. 
•  Only touch components, modules and devices when you are grounded by one of the 
following methods: 
–  Wearing an ESD wrist strap 
–  Wearing ESD shoes or ESD grounding straps in ESD areas with conductive flooring 
•  Only place electronic components, modules or devices on conductive surfaces (table 
with ESD surface, conductive ESD foam, ESD packaging, ESD transport container).
