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.
