230VAC input voltage 1312 ft (400m) 1312 ft (400m) 1312 ft (400m)
For models 5hp and less:
Insulation level of motor 1000V 1300V 1600V
460VAC input voltage 66 ft (20m) 165 ft (50m) 165 ft (50m)
230VAC input voltage 328 ft (100m) 328 ft (100m) 328 ft (100m)
NOTE
Never connect phase lead capacitors or surge absorbers to the output terminals of the Hybrid drive.
If the length is too long, the stray capacitance between cables will increase and may cause leakage current. It
will activate the protection of over current, increase leakage current or not insure the correction of current
display. The worst case is that Hybrid drive may damage.
If more than one motor is connected to the Hybrid drive, the total wiring length is the sum of the wiring length
from Hybrid drive to each motor.
For the 460V series Hybrid drive, when an overload relay is installed between the drive and the motor to protect
motor over heating, the connecting cable must be shorter than 50m. However, an overload relay malfunction
may still occur. To prevent the malfunction, install an output reactor (optional) to the drive or lower the carrier
frequency setting (Pr.00-17).
NOTE
When a thermal O/L relay protected by motor is used between Hybrid drive and motor, it may malfunction
(especially for 460V series), even if the length of motor cable is only 165 ft (50m) or less. To prevent it, please
use AC reactor and/or lower the carrier frequency (Pr. 00-17 PWM carrier frequency).
