Do not be misled by the term "low voltage." Potentials as low as 50 volts may
cause death under adverse conditions. Never work on electrical equipment unless
there is another person nearby who is familiar with the operation and hazards of
the equipment and who is competent in administering first aid. When the
technician is aided by operators, he must warn them about dangerous areas.
Whenever possible, the input power supply to the equipment must be shut off
before beginning work on the equipment. Take particular care to ground every
capacitor likely to hold a dangerous potential. When working inside the equipment,
after the power has been turned off, always ground every part before touching it.
Be careful not to contact high-voltage connections of 208 volts ac input when
installing or operating this equipment.
Whenever the nature of the operation permits, keep one hand away from the
equipment to reduce the hazard of current flowing through vital organs of the body.
Do not operate the equipment without all guards, louvers and covers in place and
tightly secure.
