Wiring the Drive

• Input fuses

– All drives must have input fuses installed in the 

power supply to the drive

– Refer to the Instruction Manual for fuse sizing

In order to fulfill the requirements of Underwriters Laboratory (UL) as was stated on page 11, 
all drives must be provided with fast-acting input power line fuses. The proper style and 
rating for these fuses is specified in the Instruction Manual on page 24.
