Chapter 1 Inspection and safety precautions
3
★Please confirm whether the input power voltage is same as the
inverter rated voltage; wiring positions of power input terminals
(R,S,T) and output terminals (U,V,W) are correct or not; and note
that if there is a short circuit in the peripheral circuit connected to
driver, if the connected lines are tight, otherwise it may cause
damage to the driver!
★Do not need to perform withstand voltage test for any part of the
inverter,this product has been tested before leaving factory.
Otherwise it may cause an accident!
★The inverter's cover plate must close before power on. Otherwise it
may cause an electric shock!
★Wiring of all external accessories must comply with the guidance
of this manual,please correctly wiring in accordance with the
circuit connection methods described in this manual. Otherwise it
may cause an accident!
★Do not open cover plate after energizing. Otherwise there is a risk
of electric shock!
★Do not touch the driver and peripheral circuits with wet hands.
Otherwise there is a risk of electric shock!
★Do not touch any input and output terminals of the inverter.
Otherwise there is a risk of electric shock!
★The inverter automatically perform the safety testing for the
external strong electrical circuit in the early stages of energizing,
therefore never touch the driver terminals (U, V, W) or motor
terminals, otherwise there is a risk of electric shock!
★If you need to identify the parameters, please pay attention to the
danger of injury during motor rotation. Otherwise it may cause an
accident!
★Please do not change the inverter manufacturer parameters.
Otherwise it may cause damage to this unit!
★Do not touch the cooling fan and the discharge resistor to feel the
temperature. Otherwise it may cause burns!
★Non-professional personnel is not allowed to detect signal when
operating. Doing so may cause personal injury or damage to this
unit!
★When the inverter is operating, you should avoid that objects fall
into this unit.Otherwise cause damage to this unit!
★Do not start/stop the driver by switching on/off contactor.
Otherwise cause damage to this unit!
★Do not perform repairs and maintenance for the live electrical
equipment. Otherwise there is a risk of electric shock!
★The repairs and maintenance task can be performed only when the
inverter voltage is lower than AC36V,generally that is two minutes
after powering off. Otherwise, the residual charge from capacitor
would cause personal injury!
★Non-well-trained professional personnel is not allowed to perform
repairs and maintenance of inverter. Doing so may cause personal
injury or damage to this unit!
★After replacing the inverter,parameter settings must be redone, all
pluggable plugs can be operated only in the case of powering off!
