SAFETY CONSIDERATIONS
The 5087A Distribution Amplifier
Safety Class I instrument (provided with a protective earth terminal),
designed and tested according to international safety standards. To ensure safe operation and to keep the
instrument in safe condition, the user must follow the information,
cautions, and warnings provided below
in the Operating and Service Manual.
WARNING
Before switching on this instrument, the protective earth terminal of the instrument must be
co~eckd
to
the protective conductor of the (mains) power cord.
The mains plug shall only be inserted in a socket
outlet provided with a protective earth contact. The protective action must not be negated by the use of an
extension cord (power cable) without a protective conductor (grounding).
Whenever it is likely that the protection has been impaired, the instrument must be made inoperative and be
secured against any unintended operation.
All protective earth terminals, extension cords, autotransformers,
and devices
connected
to
this
instrument
should be
connected
to a protective earth grounded socket outlet.
Any interruption of the protective earth
grounding will cause a potential shock hazard that could result in personal injury.
For continued protection against fire hazard, replace the line fuse only with a 250V fuse of the same cur-
rent rating and type. Do not use repaired fuses or short circuited fuseholders.
Before switching on this instrument, make sure that it is adapted to the voltage of the ac power source.
Any maintenance or service requiring removal of protective covers should be performed by service-trained
personnel who are aware of the hazard involved (for example, fire and electrical shock).
Capacitors inside the instrument may still be charged even if the instrument has been disconnected from its
source of supply.
