3. DO clean the indicators with a damp soft cloth and mild non-abrasive detergent.
4. DO remove power before cleaning with a damp cloth.

SITE PREPARATION REQUIREMENTS

The Cardinal 212G/212GX indicators are precision weight-measuring instruments. As with any
precision instrument, it requires an acceptable environment to operate at peak performance
and reliability. This section is provided to assist you in obtaining such an environment.
Electrical Power
The 212G/212GX indicators have been designed to operate from 115-230 VAC at 50/60 Hz.
Note that a special order is not required for operation at 230 VAC.
CAUTION! - To avoid electrical hazard and possible damage to the indicator,
DO NOT, under any circumstance, cut, remove, alter, or in any way bypass the
212G/212GX power cord grounding prong.
On models requiring 230 VAC power, it is the responsibility of the customer to have a
qualified electrician install the proper power cord plug which conforms to national electrical
codes and local codes and ordinances.
The AC power outlet for the 212G/212GX indicators should be on a separate circuit from the
distribution panel. This circuit should be dedicated to the exclusive use of the indicator. The
wiring should conform to national and local electrical codes and ordinances and should be
approved by the local inspector to assure compliance.
To prevent electrical noise interference, make certain all other wall outlets for use with air
conditioning and heating equipment, lighting or other equipment with heavily inductive loads,
such as welders, motors and solenoids are on circuits separate from the indicator. Many of
these disturbances originate within the building itself and can seriously affect the operation of
the instrument. These sources of disturbances must be identified and steps must be taken to
prevent possible adverse effects on the instrument. Examples of available alternatives include
isolation transformers, power regulators, uninterruptible power supplies, or simple line filters.
CAUTION! When in parallel runs, locate Load Cell cables a minimum of 24"
away from all AC wiring.
