EMC INSTALLATION GUIDELINES
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 the unit may be different for
various installations. The unit becomes more immune to EMI with fewer I/O
connections. Cable length, routing, and shield termination are very important
and can mean the difference between a successful installation or troublesome
installation.
industrial environment.
1. Use shielded (screened) cables for all Signal and Control inputs. The shield
2. Never run Signal or Control cables in the same conduit or raceway with AC
3. Signal or Control cables within an enclosure should be routed as far away as
4. In extremely high EMI environments, the use of external EMI suppression
5. Long cable runs are more susceptible to EMI pickup than short cable runs.
WIRING CONNECTIONS
Also cabling should conform to appropriate standards of good installation, local
codes and regulations. It is recommended that power supplied to the unit (AC
or DC) be protected by a fuse or circuit breaker.
Although this unit is designed with a high degree of immunity to
Listed below are some EMC guidelines for successful installation in an
(screen) pigtail 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 only at the rail where the unit is mounted to earth
b. Connect the shield to earth ground at both ends of the cable, usually when
c. Connect the shield to common of the unit and leave the other end of the
power lines, conductors feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be run in 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.
possible from contactors, control relays, transformers, and other noisy
components.
devices, such as ferrite suppression cores, is effective. Install them on Signal
and Control cables as close to the unit as possible. Loop the cable through the
core several times or use multiple cores on each cable for additional protection.
Install line filters on the power input cable to the unit to suppress power line
interference. Install them near the power entry point of the enclosure. The
following EMI suppression devices (or equivalent) are recommended:
Therefore, keep cable runs as short as possible.
All conductors should meet voltage and current ratings for each terminal.
