To avoid electrical shock hazard, disconnect power cord before removing covers. Refer servicing to
efore connecting the line cord to the AC mains, check the rear panel AC line voltage indicator.
Applying a line voltage other than the indicated voltage can destroy the AC line fuses. For continued

damage, be sure to follow proper procedures for handling, storing and transporting parts and
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 famil ia r 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 a void injuries, always disconnect power and discharge circuits before touching them.
DO NOT SERVICE OR ADJUST ALONE
Do not attempt any internal service or adjustment u nl ess another person, capable of rendering first aid and
resuscitation, is present.
DO NOT SUBSTITUTE PARTS OR MODIFY THE INSTRUMENT
