USER MANUAL

DC Power Supply

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 instructio ns and become
familiar with the operating instructions for this instrument.

Failure to comply with these prec a utio ns or with specific warnings elsewher e 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.
Operatio n of any electri cal instrument in such an environme nt 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 inst rument
covers and replacing components. Under certain conditions, even with the
power cable removed, dangerous vol t ages 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 adjust ment unless another perso n,
capable of rendering first aid and resuscitation, is present.
