Advice for Correct Installation for EMC
Instrument power supply
• Thepowersupplytotheelectronicequipmentonthe
switchboards must always come directly from an
isolation device with a fuse for the instrument part.
• Theelectronicinstrumentsandelectromechanical
power devices such as relays, contactors, solenoid
valves, etc., must always be powered by separate
lines.
• Whentheelectronicinstrumentpowersupplyis
strongly disturbed by the commutation of transistor or
power units or motors, an isolation transformer
should be used for the controllers only, earthing the
screen.
• Itisessentialthattheplanthasagoodearth
connection:
- the voltage between neutral and earth must not be >1V
 -theOhmicresistancemustbe<6Ω;
• Ifthemainsvoltagefluctuatesstrongly,useavoltage
stabilizer.
• Intheproximityofhighfrequencygeneratorsorarc
welders, use adequate mains filters.
• Thepowersupplylinesmustbeseparatefromthe
instrument input and output ones.
Inputs and outputs connection
• Theexternallyconnectedcircuitsmustbedoubly
isolated.
• Toconnecttheanalogueinputsandanalogoutputs
the following is necessary:
- physically separate the input cables from those of the
power supply, the outputs and the power connections.
- use woven and screened cables, with the screen
earthed in one point only.
• Toconnecttherelayoutputs
(contactors, solenoid valves, motors, fans, etc.), fit
RC groups (resistance and condensers in series) in
parallel to the inductive loads that operate in
Alternating Current.
(Note: all the condensers must conform to VDE
(class X2) standards and withstand a voltage of at
least 220V AC. The resistances must be at least 2Ω).
• Fita1N4007diodeinparallelwiththecoilofthe
inductive loads that operate in Direct Current.
