Switches Ensure that all switch and disconnect
settings are in the proper position.
Grounding The equipment requires a dedicated
ground wire from its chassis to the plant
ground. Check for good ground
connections that are tight and free of
oxidation.
Installation Ensure the installation box and the
box and electronics part is properly closed. Check
electronics that all four fastening screws are
part tightened with the right torque.
Cable glands Ensure the cable glands and blind plugs
and blind are properly tightened, to guarantee the
plugs right enclosure protection degree is
achieved. Liquids and/or excessive dust
ingress in the drive may result in less
than optimum performance or damage.
Vibration Look for any unusual amount of
vibration the equipment may be
subjected to. The panel should be
mounted solidly or use shock mounts as
necessary.

Converter
WARNING
HIGH VOLTAGE
Frequency converters contain high voltage when connected
to AC mains input power. 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.
1. Perform pre-start up procedure described in
section Pre-start.
2. Confirm input line voltage is balanced within 3%. If
not, correct input voltage imbalance before
proceeding. Repeat procedure after voltage
correction.
3. Ensure optional equipment wiring, if present,
matches installation application.
4. Ensure that all operator devices are in OFF position.

WARNING
UNINTENDED START
When frequency converter is connected to AC mains input
power, 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.
5. Apply power to the unit. DO NOT start the
frequency converter at this time. For units with a
disconnect switch on the mains side, turn to the
ON position to apply power to the frequency
converter.

3.3 Basic Operational Programming

Frequency converters require basic operational
programming prior to 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 this data in
accordance with the following procedure. See User Interface,
for detailed instructions on entering data through the LCP.
This data needs to be entered with power ON, but prior to
operating the frequency converter.
1. Press [Quick Menu] on the LCP.
2. Use the navigation keys to scroll to parameter
group Q2 Quick Setup and press [OK].
