PNA Series Microwave Network Analyzers Safety and Regulatory Information
N5242A General Safety Considerations
CAUTION
Do not operate the analyzer with the outer cover removed for more than
30 minutes, as this could cause the analyzer to overheat which could result in
costly damage.
WARNING
No operator serviceable parts inside. Refer servicing to qualified
personnel. To prevent electrical shock, do not remove covers.
WARNING
The opening of covers or removal of parts may expose dangerous
voltages. Disconnect the instrument from all voltage sources while it
is being opened.
WARNING
The detachable power cord is the instrument disconnecting device.
It disconnects the mains circuits from the mains supply before other
parts of the instrument. The front panel switch is only a standby
switch and is not a LINE switch (disconnecting device).
NOTE
There are no replaceable fuses in the mains input or within the power supply
assembly.
