DEADLOAD COMPENSATION
range of the input. To use this range, the output of the bridge can be offset a
small amount by applying a fixed resistor across one arm of the bridge. This
shifts the electrical output of the bridge downward to within the operating range
of the meter. A 100 K ohm fixed resistor shifts the bridge output approximately

WIRING OVERVIEW

current ratings. All cabling should conform to appropriate standards of good
installation, local codes and regulations. It is recommended that power supplied
to the meter (AC) be protected by a fuse or circuit breaker.

the wire, leaving approximately 0.3" (7.5 mm) bare lead exposed (stranded wires
should be tinned with solder). Insert the lead under the correct screw-clamp
terminal and tighten until the wire is secure. (Pull wire to verify tightness.)
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, its source or the method of coupling into the unit may be different for
various installations. 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. Never run Signal or Control cables in the same conduit or raceway with AC

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:
