Otherwise there will be unexpected danger.
There shall be circuit breaker between the inverter and power supply. Otherwise,
there may be fire.
Make sure the power is disconnected prior to the connection. Otherwise there
will be danger of electric shock.
The earth terminal shall be earthed reliably. Otherwise there may be danger of
electric shock.
Caution
Never connect the input power supply to the output terminals (U, V, W) of the
inverter. Note the terminal mark, do not connect the wrong line! Otherwise the
drive is damaged!
Please refer to the manual for the wire diameter. Otherwise there may be an
accident!
Never stop the braking resistor directly between the DC bus (+) and (-)
terminals. Otherwise cause a fire!
Encoder must use shielded wire, and the shield must ensure that the single-
ended reliable grounding!
Before Power-on
Warning
Please confirm whether the power voltage class is consistent with the rated
voltage of the inverter and the Input terminal (R
、
S
、
T) and Output
terminal(U
、
V
、
W)cable connecting positions are correct, and check whether
the external circuit is short circuited and whether the connecting line is firm,
otherwise it may damage the inverter.
Do not frequently turn ON/OFF power .If continuously ON/OFF power is
needed, please make sure the time interval more than 1 minute.
Caution
The cover must be well closed prior to the inverter power-on. Otherwise electric
shock may be caused!
All the external fittings must be connected correctly in accordance with the
circuit provided in this manual. Or accident may occur.
Upon Power-on
Warning
Do not open the cover of the inverter upon power-on. Otherwise there will be
danger of electric shock!
Do not touch the inverter and its surrounding circuit with wet hand. Otherwise
there will be danger of electric shock.
Do not touch the inverter terminals (including control terminal). Otherwise there
will be danger of electric shock.
At power-on, the inverter will perform the security check of the external strong
current circuit automatically. Thus, at this time please do not touch the terminals
U,V,W, or the terminals of motor, otherwise there will be danger of electric shock.
