SITE PREPARATION REQUIREMENTS
The Model 204 Weight Indicator is a precision weight indicating instrument. As with any
precision instrument, it requires an acceptable environment to operate at its peak performance
and reliability. This section is provided to assist you in obtaining such an environment.
Environmental
The Model 204 Weight Indicator meets or exceeds all certification requirements within a
temperature range of 14 to 104 °F (-10 to +40 °C).
In order to keep cooling requirements to a minimum, the indicator should be placed out of
direct sunlight and to provide adequate air circulation, keep the area around the indicator clear.
Do not place the indicator directly in front of a heating or cooling vent. Such a location will
subject the indicator to sudden temperature changes, which may result in unstable weight
readings.
Insure that the indicator has good, clean AC power and is properly grounded. In areas subject
to lightning strikes, additional protection to minimize lightning damage, such as surge
suppressors, should be installed.
Electrical Power
The 204 indicator has been designed to operate from 115 VAC @ 50/60Hz using a 115 VAC to
12 VDC 300 mA wall plug-in UL/CSA listed AC power adapter. NOTE! For 230 VAC
operation, an optional AC power adapter is
required, Cardinal part number 6800-1045.
 The socket-outlet supplying power to the indicator should be on a separate circuit from the
distribution panel and dedicated to the exclusive use of the indicator.
 The socket-outlet shall be installed near the equipment and shall be easily accessible.
 The wiring should conform to national and local electrical codes and ordinances and should
be approved by the local inspector to assure compliance.
 On installations requiring 230 VAC power, it is the responsibility of the customer to have
a qualified electrician install the proper power adapter plug that conforms to national
electrical codes and local codes and ordinances.
