)
Note
•
When connecting, pay attention to the polarity of the power supply. Connection with incorrect polarity may cause
damage to the driver.
•
Do not wire the power supply cable of the driver in the same cable duct with other power lines or motor cables.

DC power supply
Do not turn on or o the positive side (+) and the negative side (−) of the power supply simultaneously or
shut o only the negative side (−) of the power supply.
The main circuit and the control circuit in the driver are connected to the same ground. So the input current
of the main circuit ows round into the control circuit when the power supply is turned on or o, causing
damage to the control circuit or peripheral equipment.
