Power supplied to the system must be from dedicated, uninterrupted sources.
Power must be free of voltage dropouts, transient spikes, frequency shifts, and other
line disturbances that impair reliable performance.
If you suspect power quality problems at your site, or if your system will be installed
in a heavy industrial environment, we recommend a power quality audit before
installation. Contact us or your local electrical authority for more information.
CAUTION Avoid shock hazard.
• Only a qualified person using the appropriate measuring device shall check
the line voltage, current and frequency.
• Only our trained and certified service representatives shall attempt to service
a component that carries this symbol.
• If a protective cover on a system component appears damaged, turn off the
system and secure it against any unintended operation. Always examine the
protective cover for transport stresses after shipping.
• Even after this instrument has been disconnected from all voltage sources,
capacitors may remain charged for up to 30 seconds and can cause an
electrical shock.
• Do not allow liquid to run over or into any surface where it may gain entry into
the instrument.
• Do not attempt to remove the cover of the instrument.
Grounding
CAUTION Avoid shock hazard. Each wall outlet used must be equipped with a
ground. The ground must be a noncurrent-carrying wire connected to earth
ground at the main distribution box.
Be sure to use an appropriate grounded power cord for your electrical service. If the
power cord received is not appropriate for the electrical system in your location, or if
the power cord becomes damaged,
