BEFORE YOU BEGIN
• Apply appropriate personal protective equipment and
follow safe electrical work practices.
• NEVER work alone.
• Turn-off all power supplying the power meter and the
equipment in which it is installed before working on it.
• Always use a properly rated voltage sensing device to
confi rm that all power is off .
• Before closing all covers and doors, carefully inspect the
work area for tools and objects that may have been left
inside the equipment.
• NEVER bypass external fusing.
• NEVER open circuit a CT; use the shorting block to short
circuit the leads of the CT before removing the connec-
tion from the power meter.
• Before performing hi-pot testing on any equipment in
which the power meter is installed, disconnect all input
and output wires to the power meter. High voltage test-
ing may damage electronic components contained in
the power meter.
• The power meter should be installed in a suitable electri-
cal enclosure.
Failure to follow this instruction may result in serious
injury.
