CDE360 Vector Control AC Drive Chapter 1 Safety Information and Precautions
DANGER
Cover the AC drive properly before power-on to prevent electric shock.
The wiring of peripheral devices must be connected properly under instructions described in
this user manual. Failure to comply will result in accidents.
After power-on
DANGER
Do not open the AC drive cover after power-on. Failure to comply will result in electric shock.
Do not touch the AC drive and circuits of peripherals when use wet hands. Failure to comply
will result in electric shock.
Do not touch any I/O terminal of the AC drive. Failure to comply may result in electric shock.
Ensure that the motor and mechanical devices can bear high-speed rotating when the run
frequency is bigger than the Rated motor frequency.
During operation
DANGER
Do not touch the fan or the discharging resistor to check the temperature. Failure to comply
will result in personal burnt.
Signal detection must be performed only by qualified personnel during operation. Failure to
comply will result in personal injury or damage to the AC drive.
Avoid objects falling into the AC drive during operation. Failure to comply will result in the
damage to the AC drive.
During maintenance
DANGER
Do not repair or maintain the AC drive at power-on. Failure to comply will result in electric
shock.
After the AC drive is powered off, the basic waiting time must be ten minutes. Then repairing
or maintenance the AC drive can be performed when the DC bus voltage (between P+ and
P-) is lower than 36V. Failure to comply will result in personal injury due to the residual
voltage in the capacitor.
Repairing or maintenance of the AC drive can be performed only by qualified personnel.
Failure to comply will result in personal injury or damage to the AC drive.
Set and check parameters again after the AC drive is replaced. All plug-in components must
be plugged or removed only after power is off.
