Chapter 1 Safety and Precautions
-6-
NoteNote
5. Do not connect the input power cable
to the output ends U, V and W.
Otherwise it may damage the inverter.
6. Ensure that the wiring conforms to
EMC requirement and local safety
standard.
The diameter of the wire shall be
determined according to the manual.
Otherwise, accident may be caused!
7. The brake resistor cannot be directly
connected between terminals (+) and (-)
of DC bus. Otherwise it may cause fire.
1.1.4 Before Power-on:
Danger Danger
1. Please confirm whether the power
voltage class is consistent with the rated
voltage of the inverter and whether the
I/O cable connecting positions are
correct, and check whether the external
circuit is short circuited and whether the
wires are firmly connected. Otherwise it
may damage the inverter!
2. The cover must be well closed prior to
the inverter power-on. Otherwise electric
shock may be caused!
NoteNote
3. The inverter is free from dielectric test
because this test is performed prior to the
delivery. Otherwise accident may
occur!
4. Whether all the external fittings are
connected correctly in accordance with
the circuit provided in this manual.
Otherwise accident may occur!
1.1.5 Upon Power-on:
Danger Danger
1. Do not open the cover of the inverter
upon power-on. Otherwise there will be
danger of electric shock!
2. Do not touch the inverter and its
surrounding circuit with wet hand.
Otherwise there will be danger of electric
shock!
3. Do not touch the inverter terminals
(including control terminal). Otherwise
there will be danger of electric shock!
4. At the beginning of power-on, the
inverter will perform the security check for
the external heavy-current circuit
automatically. Thus, at this time please do
not touch terminals U, V and W, or the
terminals of motor, otherwise there will be
danger of electric shock.
NoteNote
5. If parameter identification is required,
due attention shall be paid to the danger of
injury arising from the rotating motor.
Otherwise accident may occur!
6. Do not change the factory settings at
will. Otherwise it may damage the
equipment!
