GENERAL SAFETY GUIDELINES
During installation, operation, maintenance or service, individuals may be exposed to certain components or condi-
tions including, but not limited to, refrigerants, oils, materials under pressure, rotating components, and both high and
low electrical voltages. Each of these items has the potential, if misused or handled improperly, to cause bodily injury
or death. It is essential that operating/service personnel identify and recognize these inherent hazards, protect them-
selves, and proceed safely in completing their tasks.
Work on electronic equipment should not be undertaken unless the individual(s) have been
trained in the proper maintenance of equipment and is (are) familiar with its potential hazards.
Shut off power supply to the equipment before beginning work and follow lockout procedures.
When working inside equipment with power off, take care to discharge every capacitor likely to
hold dangerous potential.
Be careful not to contact high voltage connections when installing or operating this equipment.
LOW VOLTAGE
DO NOT be misled by the term “low voltage.” Voltages as low as 50 volts may cause death.
WARNING
HIGH VOLTAGE
Is used in the operation of this equipment.
DEATH OR SERIOUS INJURY
may result if personnel fail to observe safety precautions.
