ESDS instructions and electromagnetic fields
CAUTION
An electrostatic-sensitive device (ESDS) is an individual component, integrated circuit, or
module that can be damaged by electrostatic fields or discharges.
ESDS regulations for handling boards and equipment:
When handling components that can be destroyed by electrostatic discharge, it must be
ensured that personnel, the workstation and packaging are well grounded!
Personnel in ESD zones with conductive floors may only touch electronic components if
they are
– grounded through an ESDS bracelet and
– wearing ESDS shoes or ESDS shoe grounding strips.
Electronic boards may only be touched when absolutely necessary.
Electronic boards may not be brought into contact with plastics and articles of clothing
manufactured from man-made fibers.
Electronic boards may only be placed on conductive surfaces (table with ESDS surface,
conductive ESDS foam rubber, ESDS packing bag, ESDS transport containers).
Electronic boards may not be brought close to data terminals, monitors or television sets.
Minimum clearance to screens > 10 cm).
Measurements may only be carried-out on electronic boards and modules if
– the measuring instrument is grounded (e.g. via a protective conductor) or
– before making measurements with a potential-free measuring device, the measuring head
is briefly discharged (e.g. by touching an unpainted blank piece of metal on the control
cabinet).
DANGER
It may be dangerous for people to remain in the immediate proximity of the product –
especially for those with pacemakers, implants or similar – due to electric, magnetic and
electromagnetic fields (EMF) occurring as a consequence of operation.
The machine/system operator and the people present near the product must observe the
relevant guidelines and standards! These are, for example, in the European Economic Area
(EEA) the Electromagnetic Fields Directive 2004/40/EC and the standards EN 12198-1 to
12198-3 and in the Federal Republic of Germany the Employer's Liability Insurance
Association Regulations for the Prevention of Industrial Accidents BGV 11, with the relevant
rule BGR 11 "Electromagnetic Fields".
Then a risk assessment must be carried out for every workplace, activities for reducing
dangers and exposure for people decided upon and implemented, as well as determining
and observing exposure and danger areas.
