In critical cases you should implement special EMC measures!
•
Connect snubber networks 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 earthend 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
equipotent bonding conductors between the different parts of the plant.
