Software version no.
■ High Voltage Warning
Rotating shafts and electrical equipment
can be hazardous. Therefore, it is stron
gly
recommended that all electrical work
conform to National Electrical Code (NEC) and all local
regulations. Installation, s
tart-up and maintenance
should be performed only by qualified personnel.
Motor control equipment and electronic controls are
connected to hazardous line voltages. When servicing
frequency converters and electronic controls, there will
be exposed components at or above line pote
ntial.
Extreme care should be taken to protect against shock.
Stand on an insulating pad and make it a habit to use
only one hand when checking component
s. Always
work with another person in case of an emergency.
Disconnect power whenever possible to check controls
or to perform maintenance. Be
sure equipment is
properly grounded. Wear safety glasses whenever
working on electric control or rotating equipment.
■ Warnings Against Unintended Start
1. While t
he frequency converter is connected
to the AC line, the motor can be brought to
a stop by means of external switch closures,
se
rial bus commands or references. If personal
safety considerations make it necessary to
ensure that no unintended start occurs, these
stops are not sufficient.
2. During programming of parameters, the motor
may start. Be certain that no one is in the
area of the motor or frequency converter driven
equi
pment when changing parameters
3. A motor that has been stopped may start
unexpectedly if faults occur in the electronics
of
the frequency converter, or if an overload, a
fault in the supply AC line or a fault in the motor
connection or other fault clears.

I
f the "Local/Hand" key is activated, the motor
can only be brought to a stop by means of the
"Stop/Off" key or an external safety interlock.
■ Electrostatic discharge (ESD)
Electronic components are sensitive to
electrostatic discharge (ESD). ESD can
reduce performance or destroy sensitive
electronic components. Follow proper ESD procedures
during installation or servicing to prevent damage.
