This product is a Safety Class I instrument that is provided with a protective
earth terminal when installed in the mainframe. The mainframe, amplifier,
and all related documentation should be reviewed for familiarization with
safety markings and instructions before operation or service.
Refer to the WARNINGS page (page iii) in this manual for a summary of
safety information. Safety information for preventive maintenance, 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.
