EMC INSTALLATION GUIDELINES

Although this unit is 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 the unit may be different for
various installations. In extremely high EMI environments, additional measures
may be needed. Cable length, routing and shield termination are very important
and can mean the difference between a successful or a troublesome installation.
Listed below are some EMC guidelines for successful installation in an
industrial environment.
1. Use shielded (screened) cables for all Signal and Control inputs. The shield

(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

ground (protective earth).

b. Connect the shield to earth ground at both ends of the cable, usually when

the noise source frequency is above 1 MHz.

c. Connect the shield to common of the unit and leave the other end of the

shield unconnected and insulated from earth ground.

2. 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 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.

3. 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. In extremely high EMI environments, the use of external EMI suppression

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:

Fair-Rite # 0443167251 (RLC #FCOR0000)
TDK # ZCAT3035-1330A
Steward #28B2029-0A0

Line Filters for input power cables:

Schaffner # FN610-1/07 (RLC #LFIL0000)
Schaffner # FN670-1.8/07
Corcom #1VR3

Note: Reference manufacturer’s instructions when installing a line filter.

5. Long cable runs are more susceptible to EMI pickup than short cable runs.

Therefore, keep cable runs as short as possible.

WIRING CONNECTIONS

The electrical connections are made via rear screw-clamp terminals

located on the back of the unit. All conductors should meet voltage and
current ratings for each terminal. 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. When wiring the unit, use the label to identify the wire position with
the proper function. Strip the wire, leaving approximately 1/4" bare wire
exposed (stranded wires should be tinned with solder). Insert the wire into
the screw-clamp terminal and tighten the screw until the wire is clamped
tightly. Each terminal can accept up to two #14 AWG wires.

The backlighting for a backlight version unit is powered between Terminal

2 (V+) and Terminal 1 (GND).
