Introduction
• The working area must be covered by an approved conductive
service m at that has a resistance of between 50 kΩ and 2
MΩ, and is connected directly to a reliable earth point via
its earthing cord.
• The service personnel involved must wear a wristband in
direct contact with the skin, connected to the s ervice mat.
• Printed circuit boards must be placed on the c onductive
service mat during installation, maintenance etc.
• If, for any reason, it is necessary to move the c ircuit board
from the conductive service mat, it must be placed in an
approved antistatic transportation container (e.g. static
shielding bag) before transportation.
• During installation and servicing, all electrical equipment
(soldering irons, test equipment etc.) must be earthed.
