Safety Summary
The following safety precautions apply to both operating and maintenance personnel and must be
observed during all phases of operation, service, and repair of this instrument. Before applying power,
follow the installation instructions and become familiar with the operating instructions for this
instrument.
Failure to comply with these precautions or with specific warnings elsewhere in this manual violates
safety standards of design, manufacture, and intended use of the instrument. B&K PRECISION
assumes no liability for a customer’s failure to comply with these requirements. This is a Safety Class I
instrument.
GROUND THE INSTRUMENT
To minimize shock hazard, the instrument chassis and cabinet must be connected to an electrical
ground. This instrument is grounded through the ground conductor of the supplied, three-conductor ac
power cable. The power cable must be plugged into an approved three-conductor electrical outlet. Do
not alter the ground connection. Without the protective ground connection, all accessible conductive
parts (including control knobs) can render an electric shock. The power jack and mating plug of the
power cable meet IEC safety standards.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of flammable gases or fumes. Operation of any electrical
instrument in such an environment constitutes a definite safety hazard.
KEEP AWAY FROM LIVE CIRCUITS
Instrument covers must not be removed by operating personnel. Component replacement and internal
adjustments must be made by qualified maintenance personnel. Disconnect the power cord before
removing the instrument covers and replacing components. Under certain conditions, even with the
power cable removed, dangerous voltages may exist. To avoid injuries, always disconnect power and
discharge circuits before touching them.
DO NOT SERVICE OR ADJUST ALONE
Do not attempt any internal service or adjustment unless another person, capable of rendering first aid
and resuscitation, is present.
DO NOT SUBSTITUTE PARTS OR MODIFY THE INSTRUMENT
Do not install substitute parts or perform any unauthorized modifications to this instrument. Return the
instrument to B&K Precision for service and repair to ensure that safety features are maintained.
