The following general safety precautions must be observed during all phases of operation
of this instrument. Failure to comply with these precautions or with specific warnings

use of the instrument. For safe operation the general safety precautions for the M9502A
and M9505A AXIe chassis, must be followed.
See: http://www.keysight.com/find/M9505A
Keysight Technologies Inc. assumes no liability for the customer's failure to comply with
these requirements. 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.
Inspect the shipping container for damage. If there is damage to the container or
cushioning, keep them until you have checked the contents of the shipment for
completeness and verified the instrument both mechanically and electrically. The
Performance Tests give procedures for checking the operation of the instrument. If the
contents are incomplete, mechanical damage or defect is apparent, or if an instrument
does not pass the operator's checks, notify the nearest Keysight Technologies
Sales/Service Office.
WARNING To avoid hazardous electrical shock, do not perform electrical tests when
there are signs of shipping damage to any portion of the outer enclosure (covers, panels,
etc.).
This product is a Safety Class 3 instrument. The protective features of this product may
be impaired if it is used in a manner not specified in the operation instructions.
This instrument is intended for indoor use in an installation category II, pollution degree 2
environment. It is designed to operate within a temperature range of 0 °C – 40 °C (32 °F –
105 °F) at a maximum relative humidity of 80% and at altitudes of up to 2000 meters.
This module can be stored or shipped at temperatures between -40 °C and +70 °C.
Protect the module from temperature extremes that may cause condensation within it.
To minimize shock hazard, the instrument chassis and cover must be connected to an
electrical protective earth ground. The instrument must be connected to the ac power
mains through a grounded power cable, with the ground wire firmly connected to an
electrical ground (safety ground) at the power outlet. Any interruption of the protective
(grounding) conductor or disconnection of the protective earth terminal will cause a
potential shock hazard that could result in personal injury.
Verify that all safety precautions are taken including those defined for the mainframe.
The power cable inlet of the instrument serves as a device to disconnect from the mains
in case of hazard. The instrument must be positioned so that the operator can easily
access the power cable inlet. When the instrument is rack mounted the rack must be
provided with an easily accessible mains switch.
