4-5-1Instructions for power supply<br />
CAUTION<br />
(1) Before connecting the power cable to the HA-655 driver, turn-OFF<br />
the electricity to avoid electric shock.<br />
(2) Connect the power cable to the HA-655 driver only after installing<br />
the driver on a wall.<br />
(3) Ground the HA-655 driver, to avoid electric shock, malfunctions<br />
caused by external noise, and for the suppression of radio noise<br />
emissions.<br />
4-5-2Power cable and ground cable<br />
The minimum allowable wire sizes of power cables, ground wires, and other cables are listed below. We<br />

Note 1: When bundling wires or encasing into conduits (plastic or metal pipes), use the wire of<br />
one size thicker.<br />
Note 2: In hot environments, such as the temperature in a cabinet, use heat-resistant cable (IV<br />
or HIV).<br />
Note 3: Optional cables of 3m/5m/10m long are available as follows:<br />
for a motor:<br />
for an incremental encoder:<br />
for an absolute encoder:<br />
