Safety Considerations
W A R N I N G
Any interruption of the protective (grounding) conductor (inside or
outside the system) 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 sucient
protection.) In addition, verify that a common ground exists between the
unit under test and the system prior to energizing either unit.
Whenever it is likely that the protection has been impaired, the system
must be made inoperative and be secured against any unintended
operation.
If this system 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 mains supply .)
Servicing instructions are for use by service-trained personnel only . T o
avoid dangerous electric shock, do not perform any servicing unless
qualied to do so .
A djustments described in the manual are performed with power supplied
to the system's instruments while protective covers are removed. Energy
available at many points may , if contacted, result in personal injury .
Capacitors inside the system's instruments might still be charged even if
the system has been disconnected from its source of supply .
F or continued protection against re hazard, replace the line fuses only
with 250 V fuses of the same current rating and type (for example ,
normal blow , time delay , etc .). Do not use repaired fuses or short
circuited fuse holders .
