3.2 Applying Power to the Frequency Converter
WARNING
HIGH VOLTAGE!
Frequency converters contain high voltage when
connected to AC mains. Installation, start-up and
maintenance should be performed by qualified personnel
only. Failure to comply could result in death or serious
injury.
WARNING
UNINTENDED START!
When the frequency converter is connected to AC mains,
the motor may start at any time. The frequency converter,
motor, and any driven equipment must be in operational
readiness. Failure to comply could result in death, serious
injury, equipment, or property damage.
1.
Confirm the input voltage is balanced within 3%.
If not, correct input voltage imbalance before
proceeding. Repeat this procedure after the
voltage correction.
2.
Ensure that optional equipment wiring, if present,
matches the installation application.
3.
Ensure that all operator devices are in the OFF
position. Panel doors should be closed or cover
mounted.
4.
Apply power to the unit. DO NOT start the
frequency converter at this time. For units with a
disconnect switch, turn to the ON position to
apply power to the frequency converter.
NOTE
If the status line at the bottom of the LCP reads AUTO
REMOTE COASTING or
Alarm 60 External Interlock
is
displayed, this indicates that the unit is ready to operate
but is missing an input signal on terminal 27. See
for details.
3.3 Basic Operational Programming
Frequency converters require basic operational
programming before running for best performance. Basic
operational programming requires entering motor-
nameplate data for the motor being operated and the
minimum and maximum motor speeds. Enter data in
accordance with the following procedure. Parameter
settings recommended are intended for start up and
checkout purposes. Application settings may vary. See
for detailed instructions on entering data
through the LCP.
Enter data with power ON, but before operating the
frequency converter.
