3.2 Applying Power
WARNING
HIGH VOLTAGE!
Adjustable frequency drives contain high voltage when
connected to AC line power. Installation, startup and
maintenance should be performed by qualified personnel
only. Failure to perform installation, startup and
maintenance by qualified personnel could result in death
or serious injury.
WARNING
UNINTENDED START!
When the adjustable frequency drive is connected to AC
line power, the motor may start at any time. The
adjustable frequency drive, motor, and any driven
equipment must be in operational readiness. Failure to be
in operational readiness when the adjustable frequency
drive is connected to AC line power 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
adjustable frequency drive at this time. For units
with a disconnect switch, turn to the ON position
to apply power to the adjustable frequency drive.
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
For best performance, adjustable frequency drives require
basic operational programming before running. Basic
operational programming requires entering motor
nameplate data for the motor being operated and the
minimum and maximum motor speeds. The recommended
parameter settings are intended for startup 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
adjustable frequency drive. There are two ways of
programming the adjustable frequency drive: 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.
