Lexicon MC-12 安装指导

The following general safety precautions must be observed during all phases of
operation, service, and repair of this instrument. Failure to comply with these
precautions or with specific warnings elsewhere in these instructions violates
safety standards of design manufacture and intended use of the instrument.
Lexicon, Inc. assumes no liability for failure to comply with these requirements.

To minimize shock hazard, the instrument chassis and cabinet must be
connected to an electrical ground. The instrument is equipped with a
3-conductor AC power cable. The power cable must be either plugged into an
approved 3-contact electrical outlet or used with a 3-contact to 2-contact adapter
with the grounding wire (green) firmly connected to an electrical ground (safety
ground) at the power outlet. The power jack and mating plug of the power cable
meet International Electro-technical Commission (IEC) safety standards.

Do not operate the instrument in the presence of flammable gasses or fumes.
Operation of any electrical instrument in such an environment constitutes a
definite safety hazard.

Operating personnel must not remove instrument covers. Component
replacement and internal adjustments must be made by qualified maintenance
personnel. Do not replace components with power cable connected. Under
certain conditions, dangerous voltages may exist even with the power cable
removed. To avoid injuries, always disconnect power and discharge circuits before
touching them.

Do not attempt internal service or adjustment unless another person capable of
rendering first aid and resuscitation is present.

Because of the danger of introducing additional hazards, do not install
substitute parts or perform any unauthorized modification to the instrument.

Warnings such as the example below precede potentially dangerous procedures
throughout this manual. Instructions contained in the warnings must be followed.

Dangerous voltages capable of causing death are present in
this instrument. Use extreme caution when handling, testing,
or adjusting.

The following practices minimize possible damage to
components resulting from electrostatic discharge or improper
insertion:

•

Keep parts in original containers until ready for use.

•

Avoid having plastic, vinyl, or styrofoam in the work area.

•

Wear an anti-static wrist strap.

•

Discharge personal static before handling devices.

•

Remove and insert boards with care.

•

When removing boards, handle only by non-conductive
surfaces and never touch open-edge connectors except
at a static-free workstation. To make a plastic-laminated
workbench anti-static, wash with a solution of Lux liquid
detergent, and allow to dry without rinsing.
