Preface

Thank you for choosing EPA’s VFD-L series AC Drive. The VFD-L series is manufactured using
high-quality components, material and incorporating the latest microprocessor technology available.

This manual will help in the installation, parameter setting, troubleshooting, and daily maintenance of
the AC motor drive. To guarantee safe operation of the equipment, read the following safety
guidelines before connecting power to the AC motor drive. Keep this operating manual handy and
distribute to all users for reference.

Important Notes:

 DANGER! AC input power must be disconnected before any maintenance. Do not connect or

disconnect wires while power is applied to the circuit. Only qualified technicians should perform
maintenance on the VFD-L.

 CAUTION!

components are especially sensitive to static electricity. To avoid damaging these components,
do not touch the circuit boards with metal objects or your bare hands.

 DANGER!

after the power has been turned off. To avoid personal injury, do not remove the cover of the AC
drive until all “DISPLAY LED” lights on the digital keypad are off. Please note that there are live
components exposed when the AC drive is open,. Be careful to not touch these live parts.
