GENERAL INFORMATION
1.1 Preface
This manual contains the specifications, installation instructions, description of operation, and troubleshooting
procedure for the WFC
HT
Series AC Inverters. Before installing the drive, read this manual carefully to ensure
correct installation and maximum performance. The information contained herein is considered current with
the release of version 4.2 (02-RVLVL) of the drive software.
1.2 Inspection
A. Upon receipt of the product, unpack the AC inverter and carefully inspect for any damage sustained in
transit (depression in the enclosure, damage to parts, missing parts). If damage is apparent, the freight or
express agent should be notified within 15 days of receipt of the product and a request be made that he
make an inspection of the merchandise; then a claim should be filed against the carrier. For UPS shipment
damage, save the box and packing material and notify TB Wood’s Incorporated immediately.
B. Next remove the AC inverter cover, if supplied, and inspect for any loose screws, nuts, or connectors.
C. Read the technical data plate and verify the correct horsepower size for the application and note the input
voltage and current required for the inverter.
D. If the inverter is to be stored for a long period of time, repack the inverter and store in a clean, dry place,
free from direct sunlight or corrosive fumes, and in a location where the ambient temperature will not be
less than -20° C (-4° F) nor more than 60° C (140° F).
1.3 Control Identification Number
A systematic numbering system is used to define all WFC
HT
models by torque output, input voltage rating,
horsepower rating, and enclosure type. This model number appears both on the shipping carton label and the
technical data label on the enclosure. A model number code is also accessible in the Level 1 programming
mode. (Refer to Section 4.2.)
This control number describes a constant torque, WFC
HT
adjustable frequency control in a chassis configuration, rated
7.5 HP, with input voltage of 230 VAC.
The different horsepower ratings available and code for each
rating are as follows:
