Manual VIPA HMI Chapter 3 General installation guidelines

In critical cases you should implement special EMC measures
•
Connect suppressors to all inductive loads that are not controlled by
special EMC-modules.
•
Use incandescent lamps for illumination purposes inside cabinets or
cubicles, do not use of fluorescent lamps.
Create a single reference potential and ensure that all electrical
equipment is grounded wherever possible
•
Ensure that grounding measures are implemented effectively. The
controllers are grounded to provide protection and for functional
reasons.
•
Provide a star-shaped connection between the plant, cabinets/cubicles
and the grounding/ protection system. In this way you can avoid ground
loops.
•
Where potential differences exist you must install sufficiently large
equipotential bonding conductors between the different parts of the
plant.
