EMC INSTALLATION GUIDELINES
Although Red Lion Controls products are designed with a high
degree of immunity to Electromagnetic Interference (EMI), proper
installation and wiring methods must be followed to ensure
compatibility in each application. The type of the electrical noise,
source or coupling method into a unit may be different for various
installations. Cable length, routing, and shield termination are
very important and can mean the difference between a successful
or troublesome installation. Listed are some EMI guidelines for a
successful installation in an industrial environment.
1. A unit should be mounted in a metal enclosure, which is
properly connected to protective earth.
2. Use shielded cables for all Signal and Control inputs. The
shield connection should be made as short as possible. The
connection point for the shield depends somewhat upon the
application. Listed below are the recommended methods of
connecting the shield, in order of their effectiveness.
a. Connect the shield to earth ground (protective earth) at one
end where the unit is mounted.
b. Connect the shield to earth ground at both ends of the cable,
usually when the noise source frequency is over 1 MHz.
3. Never run Signal or Control cables in the same conduit or
raceway with AC power lines, conductors, feeding motors,
solenoids, SCR controls, and heaters, etc. The cables should
be run through metal conduit that is properly grounded. This
is especially useful in applications where cable runs are long
and portable two-way radios are used in close proximity or if
the installation is near a commercial radio transmitter. Also,
Signal or Control cables within an enclosure should be routed
as far away as possible from contactors, control relays,
transformers, and other noisy components.
4. Long cable runs are more susceptible to EMI pickup than
short cable runs.
5. In extremely high EMI environments, the use of external EMI
suppression devices such as Ferrite Suppression Cores for
signal and control cables is effective. The following EMI
suppression devices (or equivalent) are recommended:
Fair-Rite part number 0443167251 (Red Lion #FCOR0000)
Line Filters for input power cables:
Schaffner # FN2010-1/07 (Red Lion #LFIL0000)
6. To protect relay contacts that control inductive loads and to
minimize radiated and conducted noise (EMI), some type of
contact protection network is normally installed across the
load, the contacts or both. The most effective location is
across the load.
a. Using a snubber, which is a resistor-capacitor (RC) network or
metal oxide varistor (MOV) across an AC inductive load is
very effective at reducing EMI and increasing relay contact
life.
b. If a DC inductive load (such as a DC relay coil) is controlled
by a transistor switch, care must be taken not to exceed the
breakdown voltage of the transistor when the load is
