Safety Summary
The following general safety precautions must be observed during all phases of operation, service, and repair
of this equipment. Failure to comply with these precautions or with specific warnings elsewhere in this manual
could result in personal injury or damage to the equipment.
The safety precautions listed below represent warnings of certain dangers of which Emerson is aware. You,
as the user of the product, should follow these warnings and all other safety precautions necessary for the
safe operation of the equipment in your operating environment.
Ground the Instrument.
To minimize shock hazard, the equipment chassis and enclosure must be connected to an electrical ground.
If the equipment is supplied with a three-conductor AC power cable, the power cable must be plugged into
an approved three-contact electrical outlet, with the grounding wire (green/yellow) reliably connected to an
electrical ground (safety ground) at the power outlet. The power jack and mating plug of the power cable meet
International Electrotechnical Commission (IEC) safety standards and local electrical regulatory codes.
Do Not Operate in an Explosive Atmosphere.
Do not operate the equipment in any explosive atmosphere such as in the presence of flammable gases or
fumes. Operation of any electrical equipment in such an environment could result in an explosion and cause
injury or damage.
Keep Away From Live Circuits Inside the Equipment.
Operating personnel must not remove equipment covers. Only Factory Authorized Service Personnel or other
qualified service personnel may remove equipment covers for internal subassembly or component
replacement or any internal adjustment. Service personnel should not replace components with power cable
connected. Under certain conditions, dangerous voltages may exist even with the power cable removed. To
avoid injuries, such personnel should always disconnect power and discharge circuits before touching
components.
Use Caution When Exposing or Handling a CRT.
Breakage of a Cathode-Ray Tube (CRT) causes a high-velocity scattering of glass fragments (implosion). To
prevent CRT implosion, do not handle the CRT and avoid rough handling or jarring of the equipment.
Handling of a CRT should be done only by qualified service personnel using approved safety mask and
gloves.
Do Not Substitute Parts or Modify Equipment.
Do not install substitute parts or perform any unauthorized modification of the equipment. Contact your local
Emerson representative for service and repair to ensure that all safety features are maintained.
Observe Warnings in Manual.
Warnings, such as the example below, precede potentially dangerous procedures throughout this manual.
Instructions contained in the warnings must be followed. You should also employ all other safety precautions
which you deem necessary for the operation of the equipment in your operating environment.
