Applying Power to the Equipment
WARNING
HIGH VOLTAGE!
Adjustable frequency drives contain high voltage when
connected to AC line power. Installation, start-up and
maintenance should be performed by qualied
personnel only. Failure to comply 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
comply could result in death, serious injury, equipment,
or property damage.
1. Conrm 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 o. Panel
doors should be 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 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, this indicates that the unit is ready to operate
but is missing an input signal on terminal 27.
