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. SEFRAM
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 SEFRAM or any certified center for service and repair to ensure that
safety features are maintained.
