ORDERING INFORMATION
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 unit may be different for various
installations. Listed below are some EMC guidelines for successful installation
in an industrial environment.
1. The unit should be mounted in a metal enclosure, which is properly connected
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
4. Signal or Control cables within an enclosure should be routed as far away as

Life Expectancy: 100,000 cycles at max. load rating. (Decreasing load
Selectable for high or low trip activation. If the process temperature goes
above the limit setpoint for a high trip, or below the limit setpoint for a low
trip, the limit relay will de-energize to initiate a process shutdown. The limit
output cannot be reset until the process temperature returns to the proper
operating range; manual reset is required (local or remote).

(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 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.

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:
Ferrite Suppression Cores for signal and control cables:
Line Filters for input power cables:
Note: Reference manufacturer’s instructions when installing a line filter.
Therefore, keep cable runs as short as possible.
