7 Safety Notices
Warnings
Before turning on the instrument, you must connect the protective earth terminal
of the instrument 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. You must not negate the protective action by using an extension
cord (power cable) without a protective conductor (grounding). Grounding one
conductor of a two-conductor outlet is not sufficient protection.
Only fuses with the required rated current, voltage, and specified type (normal
blow, time delay, etc.) should be used. Do not use repaired fuses or short-circuited
fuseholders. To do so could cause a shock or fire hazard.
If you energize this instrument by an auto transformer (for voltage reduction or
mains isolation), the common terminal must be connected to the earth terminal of
the power source.
Whenever it is likely that the ground protection is impaired, you must make the
instrument inoperative and secure it against any unintended operation.
Service instructions are for trained service personnel. To avoid dangerous electric
shock, do not perform any service unless qualified to do so. Do not attempt
internal service or adjustment unless another person, capable of rendering first aid
and resuscitation, is present.
Do not install substitute parts or perform any unauthorized modification to the
instrument.
Capacitors inside the instrument may retain a charge even if the instrument is
disconnected from its source of supply.
Do not operate the instrument in the presence of flammable gasses or fumes.
Operation of any electrical instrument in such an environment constitutes a
definite safety hazard.
Do not use the instrument in a manner not specified by the manufacturer.
