Carefully read and follow the safety precautions outlined below.
CHAPTER 2—SAFETY PRECAUTIONS
HAZARD OF ELECTRIC SHOCK, BURN, OR EXPLOSION
• Only qualified workers should install this equipment. Such work
should be performed only after reading this entire set of instructions.
• NEVER work alone.
• Before performing visual inspections, tests, or maintenance on this
equipment, disconnect all sources of electric power. Assume that all
circuits are live until they have been completely de-energized, tested,
and tagged. Pay particular attention to the design of the power
system. Consider all sources of power, including the possibility of
backfeeding.
• Turn off all power supplying this equipment before working on or
inside.
• Always use a properly rated voltage sensing device to confirm that all
power is off.
• Beware of potential hazards, wear personal protective equipment,
carefully inspect the work area for tools and objects that may have
been left inside the equipment.
• Use caution while removing or installing panels so that they do not
extend into the energized bus; avoid handling the panels, which could
cause personal injury.
• The successful operation of this equipment depends upon proper
handling, installation, and operation. Neglecting fundamental
installation requirements may lead to personal injury as well as
damage to electrical equipment or other property.
• Before performing Dielectric (Hi-Pot) or Megger testing on any
equipment in which the circuit monitor is installed, disconnect all input
and output wires to the circuit monitor. High voltage testing may
damage electronic components contained in the circuit monitor.
Failure to follow these instructions will result in death or
serious injury.
