KE600 Inverter Safety and Precautions
2
1.1.3 During Wiring:
Danger
Operation should be performed by the professional engineering technician.
Otherwise there will be danger of electric shock!
There should 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 ground terminal should be earthed reliably. Otherwise there may be danger of
electric shock.
Caution
Never connect AC power to output UVW terminals. Please note the remark of the
wiring terminals, connect them correctly. Otherwise may cause inverter damaged.
Ensure the wiring circuit can meet the requirement of EMC and the area safety
standard. Please follow the instructions in the manual before wiring. Otherwise may
cause injury or electric shock.
Never connect the braking resistor between DC bus (+), (-) terminals. Otherwise
may cause fire.
Encoder must be used together with shielded wire, and ensure the single terminal
of the shielded lay is connected with ground well.
1.1.4 Before Power-on:
Danger
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 connecting line
is firm. Otherwise it may damage the inverter. The cover must be well closed prior
to the inverter power-on. Otherwise electric shock may be caused.
The inverter is free from dielectric test because this test is performed prior to the
delivery. Otherwise accident may occur.
Caution
The cover must be well closed prior to the inverter power-on. Otherwise electric
shock may be caused!
Whether all the external fittings are connected correctly in accordance with the
circuit provided in this manual. Otherwise accident may occur!
1.1.5 After Power-on:
Danger
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
heavy-current circuit automatically. Thus, at the moment please do not touch the
terminals U, V and W, or the terminals of motor, otherwise there will be danger of
electric shock.
