Start Up and Commissioning
3.2 Applying Power
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. Parameter settings
recommended are intended for start up and checkout
purposes. Application settings may vary. See 4.1 Local
Control Panel for detailed instructions on entering data
through the LCP.

Operating Instructions
Enter data with power ON, but before operating the
frequency converter. There are two ways of programming
the frequency converter: either by using the Smart
Application Set-up (SAS) or by using the procedure
described further down. The SAS is a quick wizard for
setting up the most commonly used applications. At first
power-up and after a reset the SAS appears on the LCP.
Follow the instructions that appear on the successive
screens for setting-up the applications listed. SAS can also
be found under the Quick Menu. [Info] can be used
throughout the Smart Set-up to see help information for
various selections, settings, and messages.
NOTE
The start conditions will be ignored while in the wizard.
NOTE
If no action is taken after first power-up or reset, the SAS
screen will automatically disappear after 10 minutes.
When not using the SAS, enter data in accordance with
the following procedure.
