This equipment is a relatively complicated apparatus.

During rigging, installation, operation, maintenance,

or service, individuals may be exposed to certain com-

ponents or conditions including, but not limited to:

heavy objects, refrigerants, materials under pressure,

rotating components, and both high and low voltage.

Each of these items has the potential, if misused or

handled improperly, to cause bodily injury or death. It

is the obligation and responsibility of rigging, instal-

lation, and operating/service personnel to identify and

recognize these inherent hazards, protect themselves,

and proceed safely in completing their tasks. Failure

to comply with any of these requirements could result

in serious damage to the equipment and the property in

Indicates a possible hazardous situation

which will result in death or serious injury

if proper care is not taken.

Indicates a potentially hazardous situa-

tion which will result in possible injuries

or damage to equipment if proper care is

not taken.

Identies a hazard which could lead to

damage to the machine, damage to other

equipment and/or environmental pollu-

tion if proper care is not taken or instruc-

tions and are not followed.

Highlights additional information useful

to the technician in completing the work

being performed properly.

External wiring, unless specied as an optional connection in the manufacturer’s product line, is not

to be connected inside the control cabinet. Devices such as relays, switches, transducers and controls

and any external wiring must not be installed inside the micro panel. All wiring must be in accor-
