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. -

Agency Standards Compliance • North America: cULus Listed; UL 508C, USA File: NMMS.E244421; Canada File: NMMS7.E244421 Installation Checking the Rating Plate Before you install the VFD, check the rating plate on the side to verify that the voltage, kW (horsepower), and output current ratings are correct for your application. -
Page 5: Selecting A Motor
Selecting a Motor IMPORTANT: When selecting the motor, do not exceed the maximum output current rating of the VFD68 Drive. Motors used with the VFD68Dxx Drive must: • be AC induction three-phase motors that are UL Recognized and CSA Certified, or equivalent •... - Page 6 • Do not install the modules in airtight enclosures. • Do not install heat-generating devices that may cause the temperature to exceed the ambient operating limit in the same enclosure as the modules. The VFD68 Drive has been approved for use in an enclosure. Approval tests were conducted under the conditions in Table 2.

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: 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. IMPORTANT: Electrostatic discharge can damage VFD68 Drives. Use proper electrostatic discharge (ESD) precautions during installation and servicing to avoid damaging VFD68 Drives. -
Page 12: Terminal Screw Torque Specifications
Install a ferrite core on the signal cable (for example, ZCAT3035-1330 TDK). Terminal Screw Torque Specifications Tighten the terminal screw to the specified torque. Over-tightening the terminal screws may damage the terminal blocks and screw threads. Loose terminal screw connections can result in a short circuit or malfunction Table 6: Torque Specifications for VFD68Dxx Drives Rated Capacity, kW (HP) Tightening Torque, N•m (lb•in.) -

Page 14: Making High-Voltage Wiring Connections
Note: If the maximum wire length needs to be extended, select a larger wire size and recalculate the maximum wire length. Do not exceed 100 m. Note: Maximum wiring length is also affected by the setting of P. 72. See PWM Frequency, Audible Motor Noise, and EMI on page 24. - Page 15 2. Remove the high-voltage wiring cover at the bottom of the VFD68 Drive by pulling in the direction of Arrow A (Figure 9). Wiring Hole Figure 9: Remove the High-Voltage Wiring Cover 3. Connect a 575 VAC three-phase power supply to high-voltage terminals R/L1, S/L2, and T/L3 (Figure 10). 4.
