RF-7800W
SAFETY SUMMARY
e. Personnel must react when someone is being electrically shocked. Perform the following steps:
1. Shut off power.
2. Call for help.
3. Administer first aid if qualified.
Under no circumstances should a person come directly in contact with the body unless the power has
been removed. When immediate removal of the power is not possible, personnel must use a non-con-
ductive material to try to jolt or pry the body away from the point of shock.
f. Personnel should work with one hand whenever possible to prevent electrical current from passing
through vital organs of the body. In addition, personnel must never work alone. Someone must be
available in the immediate area to render emergency first aid, if necessary.
g. Lifting can cause injury. Items weighing more than 37 pounds must be lifted by two or more people.
h. Some electrolytic capacitors contain aluminum oxide or tantalum. If connected incorrectly, the
capacitor will explode when power is applied. Extreme care must be used when replacing and
connecting these capacitors. The capacitor terminals must always be connected using the correct
polarity: positive to positive and negative to negative.
The next section contains general safety precautions not directly related to specific procedures or equipment. These
precautions are oriented toward the maintenance technician. However, all personnel must understand and apply
these precautions during the many phases of operation and maintenance of the equipment. The following
precautions must be observed:
DO NOT SERVICE EQUIPMENT ALONE
Never work on electrical equipment unless another person familiar with the operation and hazards of the
equipment is near. When the maintenance technician is aided by operators, ensure that operators are aware
of the hazards.
GROUNDING
Always ensure that all equipment and assemblies are properly grounded when operating or servicing.
TURN OFF POWER AND GROUND CAPACITORS
Whenever possible, power to equipment should be turned off before beginning work on the equipment. Be
sure to ground all capacitors that are potentially dangerous.
KEEP AWAY FROM LIVE CIRCUITS
Operators and maintainers must observe all safety regulations at all times. Do not change components or
make adjustments inside equipment with a high voltage supply on unless required by the procedure. Under
certain conditions, dangerous potentials may exist in circuits with power controls off, due to charges
retained by capacitors.
DO NOT BYPASS INTERLOCKS
Do not bypass any interlocks unnecessarily. If it is necessary to employ an interlock bypass for equipment
servicing, use extreme care not to come in contact with hazardous voltages.
