WIRING OVERVIEW
cabling should conform to appropriate standards of good installation, local codes
and regulations. It is recommended that power supplied to the unit be protected
by a fuse or circuit breaker. As depicted in the drawing of the Model PAXLHV,
all connections are made on the terminal block located at the rear of the unit.
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 meter 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. The meter should be mounted in a metal enclosure, that 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

located on the left-hand side of the terminal block). For best results, the AC
power should be relatively “Clean” and within the specified ±10% variation
limit. Drawing power from heavily loaded circuits or from circuits that also
power loads that cycle on and off, should be avoided.

(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 meter 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 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.

3.2 INPUT SIGNAL WIRING
PAXLHV with the same voltage that is being measured, terminal 5 (COMM.)
should be connected to neutral for the most stable reading on the display. If an
unstable display results from measuring a voltage that is isolated from the supply
voltage, reversing the supply voltage connections may correct this condition.

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:
Therefore, keep cable runs as short as possible.
