Tips: Where VFD should be placed?
Most of the users installed variable frequency drive (VFD) near the MCC because it's easy to maintain the system but there are some issue's which may happen due to placing the VFD near the MCC like there is a kind voltage reflection issue if the length of the cable is more than the critical length which may damage the motor.
In this case we need to follow instructions given in the user's manual supplied with the variable frequency drive. Generally following are recommended by manufacture:
- Maximum surrounding air (Preferred);
- Ambient temperature typically -10 C to 40 C or 50 C (Check the manual for actual);
- Mounting clearances (This is related with derating of VFD).
Customize 10 hp VFD with single phase input to three phase output. Using it as a phase converter for single phase power supply to vary three phase motor speed.
