Chapter 4 Installing HA-655 driver

4-5-3 Connecting power cables
The terminal block for the power is located on the front panel of the HA-655 driver. There is no phase
order in connection to three-phase power lines.
Shown the figure to the right, strip the end of wires of the power supply
cable and the motor cable, and connect wires to each terminal firmly.
Install an isolation transformer and noise filters in the power lines to
avoid electric shock and to guard against malfunctions caused by
external noise.
The driver contains a surge-current-suppress-circuit of capacitor type. Although the circuit reduces line
voltage fluctuation, avoid daisy-chain wiring of the power lines, and connect units with a main switch.
4-5-4 Isolation transformer
The use of an isolation transformer is recommended to
prevent problems caused by improper grounding and
external noises.
Optional transformers are available as follows:
