EMC INSTALLATION GUIDELINES
Magnetic 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 meter may be different for various
installations. The meter 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 or troublesome installation.
Listed below are some EMC guidelines for successful installation in an
industrial environment.
1. The meter should be properly connected to protective earth.
2. Use shielded (screened) cables for all Signal and Control inputs. The shield
3. Never run Signal or Control cables in the same conduit or raceway with AC
To access the switches, remove the right side plate of the meter. A bank of eight
switches is located inside the unit. Note: Some switches are not used and should

Although this meter is designed with a high degree of immunity to Electro-
(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 panel 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 meter and leave the other end of the
power lines, conductors feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be ran 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.

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:
Note: Reference manufacturer's instructions when installing a line filter.
Therefore, keep cable runs as short as possible.
