Chapter 1 Inspection and Safety Precautions
Before
electrifying
notice
●Please confirm whether the voltage class of input power
is consistent with rated voltage class of inverter, whether
the circuit connected is firm enough, or it may cause the
damage of the actuator!
● There is no need in making pressure test for any part of
the inverter; the product is made such as test when it
leaves the factor, Or it may have accident!
danger
●The AC frequency vector inverters must be electrified
after its covered plates is covered well. Or it will have
electric shock hazard!
●The wiring of all outside accessories must strictly follow
the guidance of this manual; and their wirings should be
connected correctly based on the circuit connect menthol
provided by this manual. Or it may have accident!
After
electrifying danger
●Don’t open the cover plate after the electrifying. Or it
will have electric shock hazard!
● Don’t use a wet hand to touch actuator and peripheral
circuit.. Or it will have electric shock hazard!
●Don’t touch any input or output terminal of the inverter.
Or it will have electric shock hazard!
●At the beginning of electrifying, the AC frequency
vector inverters will automatically make a security
detection for outside return circuit of the strong current; at
that time, never touch U, V and W terminal blocks of the
actuator, or it will have electric shock hazard!
● Parameter identification should be made and please pay
more attention to the hazard hurting people during the
rotation of electric machine. Or it may have accident!
● Please don’t change manufacturer’s parameter of the
AC frequency vector inverters randomly. Or it may have
hazard of damaging the equipment!
In service
danger
●Never touch the cooling fan or discharge resistance to
feel out the temperature. Or it may cause burning.
● Non-professional technician can’t detect the signal
during the operation process. Or it may cause personal
injury or equipment damage!
notice
● Anything should be avoided to drop into the equipment
during the operation process of the inverter. Or it may
cause equipment damage!
● Don’t use contractor switching to control the start and
stop of the actuator. Or it may cause equipment damage!
Maintenance danger
● Please don’t repair and maintain the equipment with
electricity. Or it will have electric shock hazard!
● Maintenance and preparing can be made to the actuator
only after confirming the AC frequency vector inverters
voltage is lower than 36V, subject to two minutes after
power failure. Or residual charge on capacitance will
harm people.
● Anybody without professional training can’t make
maintenance or preparing to the inverter.
Or it may cause personal injury or equipment damage!
● Parameter setting must be made after changing the
inverter; all pluggable parts must be inserted or seized
under the condition of power failure!
