1 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.
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.
