Page 3: Introduction
VFD68 Variable Frequency Drives (575 VAC) Introduction 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. -

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 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. -
Page 13: High-Voltage Wire Size And Maximum Wire Length
High-Voltage Wire Size and Maximum Wire Length IMPORTANT: Use copper conductors only. Make all wiring in accordance with local, national, and regional regulations. Use UL Listed copper, stranded wire with insulation rated at 75°C (167°F) for wiring the high-voltage supply to the drive (R/L1, S/L2, T/L3) and wiring the high-voltage drive output (U, V, W) to the motor. -
