truck frames is generally a suggested not expensive solution to reduce
the emission level.
2) ELECTROMAGNETIC IMMUNITY. The considerations made for emissions
are valid also for immunity. Additionally, further protection can be achieved
with ferrite beads and bypass capacitors.
3) ELECTROSTATIC IMMUNITY. Three ways can be followed to prevent
damages from ESD:
A) PREVENTION: when handling ESD-sensitive electronic parts, ensure the
operator is grounded; test grounding devices on a daily basis for correct
functioning; this precaution is particularly important during controller
handling in the storing and installation phase.
B) ISOLATION: use anti-static containers when transferring ESD-sensitive
material.
C) GROUNDING: when a complete isolation cannot be achieved, a good
grounding can divert the discharge current trough a “safe” path; the
frame of a truck can works like a “local earth ground”, absorbing excess
charge. So it is strongly suggested to connect to truck frame all the
parts of the truck which can be touched by the operator, who is
most of the time the source of ESD.
