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. 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.
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
ELECTRICAL CONNECTIONS & INPUTS
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 voltage connections to the
unit be protected by a fuse or circuit breaker.
The CUB3T’s can be supplied with input signals from mechanical switch
contacts or solid-state switches as shown in the diagrams below. Reed switches,
mercury-wetted contacts, snap-action limit switches, and silver alloy contacts
with wiping action are usually satisfactory choices for mechanical switch input.
Heavy “clapper-type” contacts such as used in contactors or large machine tool
relays, tungsten contacts, or brush type contacts are not recommended for the
low level switching used by the input to the timer.
To avoid injury to personnel or equipment, properly isolate all unused wires.
For example, wire nuts, closed end splices, or other types of wire terminators
should be used.
Warning : Connecting voltage to contact or reset inputs will cause damage to
the unit.
10 to 300 V Voltage Connections
Warning: Any lead may be at hazardous live input potential. External
wiring and devices connected to the unit must be rated the same as
applied signal input voltage and be properly isolated from Class 2
or SELV circuitry.
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
CUB3T4
protection. 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
5. Long cable runs are more susceptible to EMI pickup than short cable runs.
Therefore, keep cable runs as short as possible.

TYPICAL APPLICATIONS
An equipment rental company charges customers by the hour for the
rental of forktrucks or other heavy equipment. To help determine the amount
of actual run time, a CUB3T300 is connected to a spare set of contacts on
the ignition switch of the forktruck. When the switch is in the “RUN”
position, the “Orn/Wht” and “White” leads of the CUB3T3 are connected,
which cause it to accumulate time in hours on the display. The rental
company simply resets the CUB3T3 by momentarily closing the connection
between the “Orn/Wht” and “Blue” leads before each rental period. The
normally open “REMOTE RESET” push-button (installed by the rental
company) is protected to prevent tampering by the customer.
The unit should be installed in a location that does not exceed the maximum
operating temperature and provides good air circulation. Placing the unit near
devices that generate excessive heat should be avoided.
The bezel should be cleaned only with a neutral soap product applied to a
soft damp cloth. Do NOT use solvents.
Continuous exposure to direct sunlight may accelerate the aging process of
the display.
Do not use tools of any kind (screwdriver, pens, pencils, etc.) to operate the
reset button of this unit.

A machine shop manager charges customers for machine time by the
hour. He is also interested in tracking machine run time vs. down time. A
CUB3T310 connected across the 115 VAC spindle motor of a drill press will
serve both purposes. A reading taken before and after each job will indicate

beginning and end of each shift will indicate total run time, allowing the
manager to evaluate production efficiency and down time.
