Safety Considerations Installation and Maintenance
Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Sixth Edition 289
Safety Considerations
The Agilent 8163A/B Lightwave Multimeter System, Agilent 8164A/B
Lightwave Measurement System, and the Agilent 8166A/B Lightwave
Multichannel System are Safety Class 1 instruments (that is, instruments
with a metal chassis directly connected to earth via the power supply
cable). The shown symbol is used to show a
protective earth terminal in
the instrument.
Before operation, review the instrument and manual for safety markings
and instructions. You must follow these to ensure safe operation and to
maintain the instrument in safe condition.
Some Agilent 8164A/B Lightwave Measurement System and
Agilent 8166A/B Lightwave Multichannel System circuits are powered
whenever the instrument is connected to the AC power source. To
disconnect from the line power, disconnect the power cord either at the
rear power inlet, or at the AC line power source (receptacle). One of these
must always be accessible. If the instrument is in a cabinet, it must be
disconnected from the line power by the system’s line power switch.
