3. Wiring requirements
a.Shielded wire (screened cable) is required fo r motor wiring but is not required for direct 
reactor wiring. And, the length of the cable  must be according to the following table.
b. The carrier frequency setting must be less than 3 kHz (derated is required) to meet an 
EMC requirement.
c. The main circuit wiring must be sepa rated from the control circuit wiring.
