3.2.4 Main Circuit Terminals and Wiring
Danger
1.Before wiring, make sure the power switch is OFF,otherwise,can lead to
electric shock.
2. Only trained professionals can do wiring, so as to avoid the risk of the drive
damage and the personal Injury.
3.The drive must be properly earthed to reduce electrical accident and fire.
Attention
1. Ensure that the drive’s rated input voltage is identical with the AC supply
voltage before using it.
2.Confirm the motor and the drive adaptation, otherwise, make damage the
drive or cause the motor triping.
3. It is prohibited to connect the AC supply cables to the drive’s terminals U, V
and W.
4. Braking resistor can not be directly connected to the DC bus (+),(-).
