DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe electrical
practices. For example, in the United States, see NFPA 70E.
• This equipment must only be installed and serviced by qualified electrical
personnel.
• 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 equipment.
• Always use a properly rated voltage sensing device to confirm that all power is off.
• Beware of potential hazards and 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 power meter is installed, disconnect all input and output wires to the power
meter. High voltage testing may damage electronic components contained in the
power meter.
• Always use grounded external CTs for current inputs.
Failure to follow these instructions will result in death or serious injury.
