Safety Summary
The following general safety precautions must be observed during all phases of the
operation, service, and repair of this product. Failure to comply with these
precautions or with specific warnings elsewhere in this manual violates safety
standards of design, manufacture, and intended use of this product.
GE assumes no liability for the customer's failure to comply with these requirements.
Ground the System
To minimize shock hazard, the chassis and system cabinet must be connected to an
electrical ground. A three-conductor AC power cable should be used. The power
cable must either be plugged into an approved three-contact electrical outlet or used
with a three-contact to two-contact adapter with the grounding wire (green) firmly
connected to an electrical ground (safety ground) at the power outlet.
Do Not Operate in an Explosive Atmosphere
Do not operate the system in the presence of flammable gases or fumes. Operation of
any electrical system in such an environment constitutes a definite safety hazard.
Keep Away from Live Circuits
Operating personnel must not remove product 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 Service or Adjust Alone
Do not attempt internal service or adjustment unless another person, capable of
rendering first aid and resuscitation, is present.
Do Not Substitute Parts or Modify System
Because of the danger of introducing additional hazards, do not install substitute
parts or perform any unauthorized modification to the product. Return the product
to GE for service and repair to ensure that safety features are maintained.

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