Risk of electrical shock
The VFD67 drive remains electrically charged for a period of time after the power is
removed. To avoid possible electrical shock, wait at least 10 minutes after AC supply
power has been disconnected from the VFD67 drive before servicing the control. Failure
to wait until the VFD67 drive fully discharges could cause electrical shock, personal
injury, or death.
WARNING
Risk of equipment damage
Connect each of these items to the VFD67 drive using a separate conduit for each set
of wires:
•
Line voltage supply power
• Line voltage output power to motor
• Low voltage signals from input devices
Running different voltage and frequency wires in the same conduit can create electronic
noise or harmonics, which may damage the condenser fan motors.
