Page 5: Selecting A Motor
For example, a VFD68BGG would be rated for 200–240 VAC and 2 horsepower. IMPORTANT: Frequently starting and stopping the VFD shortens the lifespan of the VFD68 drive. In applications where the drive will start or stop frequently, select a VFD which has an output current rating that is 1.5 to 2 times greater than the FLA current rating of the three-phase motor. - Page 6 Observe the following location guidelines: • Ensure that the mounting surface can support the drive, mounting hardware, and any user-supplied panel or enclosure. • Mount drives on flat, even surfaces. • Allow sufficient space for wires and connections. • Do not mount the modules on surfaces that are prone to vibration or in locations where radio frequency or electromagnetic emissions may cause interference.

Page 10: Wiring
Wiring WARNING: Risk of Electric Shock. Disconnect the power supply before making electrical connections. Contact with components carrying hazardous voltage can cause electric shock and may result in severe personal injury or death. AVERTISSEMENT: Risque de décharge électrique. Débrancher l'alimentation avant de réaliser tout branchement électrique. Tout contact avec des composants porteurs de tensions dangereuses risque d'entraîner une décharge électrique et de provoquer des blessures graves, voire mortelles. -
Page 11: Precautions
IMPORTANT: Do not exceed the VFD68 drive's electrical ratings. Exceeding the drive's electrical ratings can result in permanent damage to the drive and void any warranty. IMPORTANT: Run all low-voltage wiring and cables separate from all high-voltage wiring. Shielded cable is strongly recommended for input (sensor) and analog output cables that are exposed to high electromagnetic or radio frequency noise. -
Page 12: Terminal Screw Torque Specifications
• Prevent VFD-generated EMI from causing functional problems. Do not run the low-voltage signal cables and the high-voltage power cables in parallel with each other, and do not bundle them together. Run low-voltage signal cables as far away as possible from high-voltage power cables. Use shielded cables for the low-voltage signal cables. -
