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. In extremely high EMI environments, additional measures
may be needed. 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 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
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.

supply. The external supply is connected between V+ and Common terminals as
shown in the drawing.
Although this unit is designed with a high degree of immunity to
(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.
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:
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.
Optional backlight versions of the CUB7 require an external 9-28 VDC power

WIRING CONNECTIONS
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 battery cover 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 under the screw-clamp and tighten down the screw
until the wire is clamped in tightly. Each terminal can accept up to two #14
AWG wires.
BATTERY INSTALLATION
1. Remove all power to the unit before removing battery cover.
2. To remove battery cover, push upward in the direction of the arrow on
3. Remove old battery* and replace with an RLC battery (BNL10000).
4. Replace cover. The battery cover is keyed so that it cannot be placed
* - Dispose of properly.
The electrical connections are made via screw-clamp terminals located
rear cover (See drawing at right), until the cover unlatches. Pull cover
straight out from unit to fully remove.
Observe proper polarity when replacing battery as shown in drawing.
upside down. The arrow on the rear of the cover should point toward the
top of the CUB7 when properly installed
WARNING: Lithium battery may explode if incinerated. Signal input
voltage should not exceed 3 VDC to prevent damage to the counter.
