Chapter 5 - Operation
Precautions:
1.
Motor rotation MUST be checked in both VFD and Bypass modes.
Failure to confirm rotation may cause severe damage to the
Electronic bypass, motor or its driven equipment.
2. Only turn ON the input power supply after closing the front door.
3. Do not touch the VFD heatsink, which operates at a very high temperature.
4. Since it is easy to change operation from low to high speed, verify the safe
working range of the motor and connected load before operation.
5.
DO NOT
check signals during operation
.
6. VFD parameters have been factory set for operation in the Electronic
bypass package.
DO NOT
change these settings, as this will result in
improper operation.
Failure to observe these precautions may result in equipment damage,
serious personal injury or death.
