The optical receiver complies with overvoltage category II and pollution degree
2. It can operate from the single-phase AC power source that supplies between
100 V and 240 V (max. voltage fluctuation 10%) at a frequency in the range of 50
to 60 Hz. The maximum power consumption of the optical receiver is 300 VA.
Please refer to the documentation for your UXR-Series oscilloscope for
information on its line power requirements.

In accordance with international safety standards, the instrument has a
three-wire power cable. When connected to an appropriate AC power
receptacle, this cable earths the instrument cabinet. The type of power
cable shipped with each instrument depends on the country of destination.
To avoid the possibility of injury or death, you must observe the following
precautions before switching on the instrument.
• Insert the power cable plug only into a socket outlet provided with a
protective earth contact. Do not use an extension cord without a protective
conductor. Using an extension cord without a protective conductor means
the instrument is not earthed.
• Do not interrupt the protective earth connection intentionally.
• Do not remove protective covers. Operating personnel must not remove
instrument covers. Component replacement and internal adjustments must
be made only by qualified service personnel.
• Instruments that appear damaged or defective should be made inoperative
and secured against unintended operation until they can be repaired by
qualified service personnel.
• Defective, damaged, or malfunctioning instruments must be returned to an
Keysight Technologies Service Center.
• Do not operate the instrument in the presence of flammable gases or fumes.
Operation of any electrical instrument in such an environment constitutes a
definite safety hazard.
