especially the screws withe red marks.
t
Do not drop wire end or screw into the AC drive.
Failure it will result in damage to the AC drive.
t
arrange the installation positions properly to ensure
the cooling effect.
t
When two AC drives are laid in the same cabinet ,
t
Install the AC drive in places free of vibration and
direct sunlight.
Danger
t
A circuit breaker must be used to isolate the power
supply and the AC drive. Failure to comply may result
a fire.
t
Ensure that the power supply is cut off before wiring.
Failure to comply may result in electric shock.
t
Never connect the power cables to the output
terminals(U,V,W) of the AC drive. Pay attention to the
marks of the wiring terminals and ensure correct
wiring. Failure to comply may result in damage to the
AC drive.
t
Never connect the power cables the braking resistor
between the DC bus terminals P+, P-. Failure to
comply may result in a fire.
t
Ensure that the main cable line comply with the
standard, the line meets the EMC requirements and
the area safety standard. Failure to comply may result
in risk or accident.
