Safety Considerations
WARNING
Chapter 1
This product is a Safety Class I instrument that is provided with a protective
earth terminal when installed in the mainframe. The instrument, mainframe,
and all related documentation should be reviewed for familiarization with
safety markings and instructions before operation or service.
Refer to the WARNINGS page (page 6) in this manual for a summary of
safety information. Safety information for testing and service follows and is
also found throughout this manual.
This section contains WARNINGS which must be followed for your
protection and CAUTIONS which must be followed to avoid damage to the
equipment when performing instrument maintenance or repair.
SERVICE-TRAINED PERSONNEL ONLY. The information in this
manual is for service-trained personnel who are familiar with
electronic circuitry and are aware of the hazards involved. To
avoid personal injury or damage to the instrument, do not
perform procedures in this manual or do any servicing unless
you are qualified to do so.
CHECK MAINFRAME POWER SETTINGS. Before applying
power, verify that the mainframe setting matches the line
voltage and that the correct fuse is installed. An uninterruptible
safety earth ground must be provided from the main power
source to the supplied power cord set.
GROUNDING REQUIREMENTS. Interruption of the protective
(grounding) conductor (inside or outside the mainframe) or
disconnecting the protective earth terminal will cause a
potential shock hazard that could result in personal injury.
(Grounding one conductor of a two-conductor outlet is not
sufficient protection.)
IMPAIRED PROTECTION. Whenever it is likely that instrument
protection has been impaired, the mainframe must be made
inoperative and be secured against any unintended operation.
REMOVE POWER IF POSSIBLE. Some procedures in this
manual may be performed with power supplied to the
mainframe while protective covers are removed. Energy
available at many points may, if contacted, result in personal
injury. (If maintenance can be performed without power
applied, the power should be removed.)
