8200-M129-O1 Rev D 205 Installation & Technical 5
SITE PREPARATION REQUIREMENTS
The Cardinal 205 indicator is a precision weight-measuring instrument. As with any precision
instrument, they require an acceptable environment to operate at peak performance and
reliability. This section is provided to assist you in obtaining such an environment.
Environmental
The Model 205 indicator meet 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.
Make certain the indicator is not 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 205 indicator has been designed to
operate from 100 to 240 VAC at 50/60 Hz.
Note that a special order is not required
for operation at 230/240 VAC.
WARNING! To avoid electrical hazard and possible damage to the indicator,
DO NOT, under any circumstance, cut, remove, alter, or in any way bypass the
power cord grounding prong.
• 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.
Note that the power cord on the 205 serves as the power disconnect.
• The wiring should conform to national and local electrical codes and ordinances and should
be approved by the local inspector to assure compliance.
• For outdoor operations, the socket-outlet must provide GFCI (ground fault circuit
interrupter) protection.
• On installations requiring 230/240 VAC power, it is the responsibility of the customer to
have a qualified electrician install the proper power cord plug that conforms to national
electrical codes and local codes and ordinances.
