5.2 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 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 that the input voltage is balanced within
3%. If not, correct input voltage imbalance before
proceeding.
2. Ensure that optional equipment wiring, if present,
matches the installation application.
3. Ensure that all operator devices are off. 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 the switch on to apply
power.
NOTICE
If the status line at the bottom of the LCP reads AUTO
REMOTE COASTING or Alarm 60 External Interlock is
displayed, the unit is ready to operate but is missing an
input signal on terminal 27.
