The VFD68 Variable Frequency Drives are designed to provide three-phase motor speed
control in a variety of HVACR applications. The VFD68 Drives are factory-configured for
condenser fan speed control on HVACR condensing units. You can quickly and easily
reconfigure the VFD68 Drives to control variable speed pumps in cooling and heating
applications, or to drive variable speed supply fans in VAV applications.
This document provides information for VFD68Bxx (230 VAC) and VFD68Cxx (460 VAC)
Drive models only. For information pertaining to VFD68Dxx (575 VAC) Drive models, refer
to the VFD68 Variable Frequency Drive (575 VAC) Installation Instructions (Part
No. 24-7664-3116).
Note: The VFD68 Drive cannot drive motors in conveyor systems or robotic
applications.
Important: Use this VFD68 Variable Frequency Drive only as an operating control.
Where failure or malfunction of the VFD68 Drive could lead to personal injury or
property damage to the controlled equipment or other property, additional precautions
must be designed into the control system. Incorporate and maintain other devices, such
as supervisory or alarm systems or safety or limit controls, intended to warn of or
protect against failure or malfunction of the VFD68 Drive.
Important: Utiliser ce VFD68 Variable Frequency Drive uniquement en tant que
dispositif de régulation. Lorsqu'une défaillance ou un dysfonctionnement du VFD68 Drive
risque de provoquer des blessures ou d'endommager l'équipement contrôlé ou un autre
équipement, la conception du système de contrôle doit intégrer des dispositifs de
protection supplémentaires. Veiller dans ce cas à intégrer de façon permanente d'autres
dispositifs, tels que des systèmes de supervision ou d'alarme, ou des dispositifs de
sécurité ou de limitation, ayant une fonction d'avertissement ou de protection en cas de
défaillance ou de dysfonctionnement du VFD68 Drive.
Note: Do not attempt to install, operate, maintain, or inspect the VFD68 Drive
until you have read through this document carefully and can use the equipment correctly.
Do not use this product until you fully understand the equipment, safety information,
and instructions.
See the VFD68 Variable Frequency Drive Technical Bulletin (Part No.
24-7664-3051), which covers 230 VAC, 460 VAC, and 575 VAC models, for more
