2.3 Attention Of Wiring
Warning
1.
Before connecting, please make sure the power supply has been cut off for more
than 10min, otherwise, there would be electric shock danger.
2.
Never to connect the power line to the output terminals U,V,W of drive.
3.
Because there is leakage current in the drive, the drive and motor must
be grounded safely, the ground wire shall be copper conductor of more than
3.5mm²
(refer to diagram3-1), and the grounding resistance shall be less than 10Ω.
4.
User shall not conduct the withstand voltage test for the drive as it has passed
this test before leaving factory.
5.
Between drive and motor shall not be installed with electro-magnetic contactor
and absorbing capacitor or another resistance--capacitance absorbing
implements as diagram 1-4
6.
To take the convenience for over-current protection of input side and power failure
maintenance, the drive shall be connected to power supply through intermediate
breaker.
7.
DI and DO connect wire should choose more than 0.75mm²twisted wire or
shielded wire,
Detail refer to 3.7.2 Field Wiring and the grounding wire shall be less 50m.
Danger
1.
Make sure the power supply of drive has been cut off thoroughly, all LED lamps of
Keyboard has went out, and wait for 10 min, confirm the DC current voltage value
between the drive main circuit terminal (+) (-) to drop below DC36V, till now, can
perform the wiring operation.
2.
Only the qualified professional who has been trained and authorized can perform
the wiring operation.
3.
Please pay attention that before energizing, check whether the voltage class of drive is
identical with the supply voltage, otherwise, it would be result in person casualty and
damage of device.
