Chapter 1 Safety and Notes
1.1 Safety Notes
1. The AC drive should be installed and adjusted by professional electrical technicians, otherwise there is
a danger of electric shock!
2. Make sure the power is off before wiring, otherwise there is a danger of electric shock!
3. Ground terminal must be reliably grounded, ground resistance should be less than 0.1
Ω
!
4. Do not connect the input power to the output U, V, W, otherwise the AC drive will be damaged!
5. Make sure wires diameter be accord with technical standards, otherwise fault will happen.
6. No voltage test is required for AC drive, this item has been tested when leave the factory.
7. Do not touch the AC drive terminal (Includes control terminal) after power on, otherwise there is a
danger of electric shock!
8. If you want to do parameter self-learning, please be aware of the risk of injury during motor rotation,
otherwise it may cause an accident!
9. Do not control the start and stop of the ac drive by the contactor on or off, otherwise the equipment will
be damaged!
10. AC drive cannot be repaired or maintained immediately because there is still high voltage on the filter
capacity after the power off. It needs to wait for more than 5 minutes before using a multimeter to measure
the bus voltage (the voltage between (+) and (-)) should not exceed 36V.
11. Do not share the ground terminal PE with the power line terminal N!
1.2 Notes
1. Insulation checking of motors
Make sure to separate the motor connection from the AC drive during insulation test(checking), It is
recommended to use 500V voltage megohm meter and should guarantee the measured insulation
resistance is not less than 5 m
Ω
.
2. About motor thermal and noise
The output voltage of the AC drive is PWM wave, which contains certain harmonics, so the temperature
rise, noise and vibration of the motor will increase slightly compared with the operation of power
frequency.
3. The output side cannot connect to the pressure sensitive device or improved the power factor of
capacity.
4. Protection against lightning strike
This series AC drive is equipped with lightning overcurrent protection device, which has certain
self-protection ability for inductive lightning. For frequent lightning, users should also install lightning
protection at the front of the AC drive.
5. Disposing unwanted drive
