WIRING OVERVIEW
from the rear of the unit. When using the optional terminal block, the #22 AWG
colored wires are cut off and electrical connections are made via screwless type
terminal block. All conductors should conform to the meter’s voltage and
current ratings. All cabling and wire terminations should conform to appropriate
standards of good installation, local codes and regulations. It is recommended
that the backlight power supplied to the meter (DC or AC) be protected by a fuse
or circuit breaker.
EMC INSTALLATION GUIDELINES
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 meter may be different for various
installations. The meter 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 or 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, which is properly
2. Use shielded (screened) cables for all Signal and Control inputs. The shield

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

heaters, etc. The cables should be ran in metal conduit that is properly
grounded. This is especially useful in applications where cable runs are long

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:
