Notices
FCC PART 15 NOTICE This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe electrical
work practices. In the USA, see NFPA 70E or CSAZ462.
• Only qualified electrical workers should install this equipment. Such work should be
performed only after reading this entire set of instructions.
• If the equipment is not used in a manner specified by the manufacturer, the protection
provided by the equipment may be impaired.
• 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 back feeding.
• Turn off all power supplying the meter and the equipment in which it is installed before
working on it.
• Always use a properly rated voltage sensing device to confirm that all power is off.
• Before closing all covers and doors, inspect the work area for tools and objects that
may have been left inside the equipment.
• When removing or installing panels, do not allow them to extend into the energized
bus.
• 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
energy meter is installed, disconnect all input and output wires to the energy meter.
High voltage testing may damage electronic components contained in the energy
meter.
• This equipment should be installed in a suitable electrical enclosure.
Failure to follow these instructions will result in death or serious injury.
