WARNING
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.)
USING AUTOTRANSFORMERS. If the mainframe is to be
energized via an autotransformer (for voltage reduction) make
sure the common terminal is connected to neutral (that is, the
grounded side of the main's supply).
CAPACITOR VOLTAGES. Capacitors inside the mainframe
may remain charged even when the mainframe has been
disconnected from its source of supply.
USE PROPER FUSES. For continued protection against fire
hazard, replace the line fuses only with fuses of the same
current rating and type (such as normal blow, time delay, etc.).
Do not use repaired fuses or short-circuited fuseholders.
SHOCK HAZARD. Only service-trained personnel who are
aware of the hazards involved should install, remove, or
configure the Agilent E1463A 32-Channel Form C Switch
Module . Before you remove any installed module, disconnect
AC power from the mainframe and from other modules that
may be connected to the Switch Module.
CHANNEL WIRING INSULATION. All channels that have a
common connection must be insulated so that the user is
protected from electrical shock. This means wiring for all
channels must be insulated as though each channel carries
the voltage of the highest voltage channel.
