Matters
◆
When two or more frequency converters are set in the same cabinet, please
pay attention to the installation site and guarantee heat dissipation.
At wiring
Danger
◆
The construction must be implemented by the professional electric
engineering personnel, or else, the unexpected danger may occur!
◆
The frequency converter and the power supply must be separated by the
circuit breaker, or else, the fire alarm may occur!
◆
Please ensure that the power supply is in zero energy state before wiring,
or else, the electric shock may occur!
◆
The frequency converter shall grounded appropriately according to the
standard, or else, the electric shock may occur!
Warning
◆
Please never connect the power supply to the output terminal (U, V, W) of
the frequency converter. Pay attention to the mark on the terminal block to
avoid inappropriate wiring, or else, the driver may be damaged!
◆
Please never directly connect the brake resistance between (+) terminal of
DC bus and (-) terminal of DC bus, or else, the fire alarm may occur!
◆
Please see the manual for the diameter of lead wire, or else, there may be
an accident !
◆
The encoder must be set with the shielded wire and it is required to ensure
that the single end of shield is grounded stably!

Danger
◆
Please confirm whether the voltage class of power supply is in line with
the rated voltage class of frequency converter; confirm whether wiring
position on the input terminal (R, S, T) and output terminal (U, V, W) is
correct; inspect whether there is short circuit in the peripheral circuit
connected to the frequency converter and whether the circuit is reliable, or
else, the frequency converter may be damaged!
◆
It is not necessary to conduct the withstand voltage test on any parts of the
frequency converter, because the frequency converter has passed this test
before delivery. Or else, there may be an accident!
Warning
◆
The frequency converter must be covered well before power supply, or
else, the electric shock may occur!
◆
The wiring of all peripherals must be in line with this manual and shall be
implemented in the method given in the manual, or else, there may be an
accident!
