7.1 Connecting the power supply
Connecting method
1. Strip the insulation of the lead wire by 10 mm (0.39 in.).
Applicable lead wire: AWG 16 to 10 (1.25 to 6 mm
2
)
2. Insert each lead wire into the CN1 connector and tighten the screw.
Tightening torque: 0.7 to 0.8 N·m (6.1 to 7.0 lb-in)

3. Insert the CN1 connector into the CN1 on the driver.
Hold the green part of the CN1 connector, and insert it into the CN1 on the driver.
Push the lever (orange) into the CN1 on the driver before pulling out the CN1 connector.
Supplying the power in a state where the lever (orange) is pushed
in may cause damage to the driver due to connection failure.
Note
•
For the power supply, use a DC power supply with reinforced insulation on its primary and secondary sides.
•
When connecting, check the indication of the driver case and pay attention to the polarity of the power
supply. Reverse-polarity connection 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
cable. Doing so may cause malfunction due to noise.
•
When turning on the power again or inserting/pulling out the connector, turn o the power and wait for
the POWER LED to turn o.
Notes for power ON/OFF using a mechanical contact
•
When turning on or o the power supply using a mechanical
contact (breaker, electromagnetic switch, relay, etc.), do so only
the positive side (+) of the power supply using the mechanical
contact.

DC power supply
Do not turn on or o the positive side (+) and the negative side (–) of the power supply simultaneously
using a mechanical contact. Also, do not 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.
