    Access Access must be restricted to authorized personnel only. Safety regulations which apply at the place of use must be complied with. The IP (Ingress Protection) rating of the drive is installation dependant. Compliance and regulations The installer is responsible for complying with all relevant regulations, such as national wiring regulations, accident prevention regulations and electromagnetic compatibility (EMC) regulations.
  • Page 7 If the drive has failed in a manner that causes the display to go blank immediately, it is possible the capacitors will not be discharged. In this case, consult Johnson Controls Inc or their authorized distributor.
  • Page 8 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 WARNING to wait until the VFD67 drive fully discharges could cause electrical shock, personal injury, or death.
