Safety Instructions
Before You Begin
Carefully observe these safety instructions before installing, repairing, servicing, or
maintaining electrical equipment.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
b Apply appropriate personal protective equipment (PPE) and follow safe
electrical work practices. In the USA, see NFPA 70E.
b Only qualified electrical workers should install this equipment. Such
work should be performed only after reading this entire set of
instructions.
b NEVER work alone.
b Before performing visual inspections, tests, or maintenance of 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.
b Turn off all power supplying the power meter and the equipment in
which it is installed before working on it.
b Always use a properly rated voltage sensing device to confirm that all
power is off.
b Before closing all covers and doors, carefully inspect the work area for
tools and objects that may have been left inside the equipment.
b 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.
b Successful equipment operation requires proper handling, installation,
and operation. Neglecting fundamental installation requirements may
lead to personal injury as well as damage to electrical equipment or
other property.
b NEVER bypass external fusing.
b NEVER short the secondary of a Power Transformer (PT).
b NEVER open circuit a Current Transformer (CT); use the shorting block
to short circuit the leads of the CT before remooving the connection
from the power meter.
b 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.
b The power meter should be installed in a suitable electrical enclosure.
Failure to follow these instructions will result in death or serious injury.
