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 perform installation, start-up and
maintenance by qualified personnel 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 be in operational readiness when the
frequency converter is connected to AC mains could result
in death, serious injury, equipment, or property damage.
1.
Confirm input voltage is balanced within 3%. If
not, correct input voltage imbalance before
proceeding. Repeat procedure after voltage
correction.
2.
Ensure optional equipment wiring, if present,
matches installation application.
3.
Ensure that all operator devices are in the OFF
position. Panel doors 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 COAST, this indicates that the unit is ready to
operate but is missing an input signal on terminal 27.
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.
