Installation and Wiring
3.1 Safety Precautions
This chapter explains the warnings that must be followed to ensure that the user can safely use the product, maximize the performance of the drive, and
ensure reliable operation of the drive.
Cautions in use:
● While install the drive in the closed cabinet, please build in cooling fan, air-conditioner or other cooling equipment to ensure
the temperature at the air-in port below 40℃. So that the drive can work safely and reliably.
● While installing, please use cloth or paper cover the drive to prevent metal dust, oil, water and others.And remove it carefully
after working.
● While operation, please follow the ESD regulations. Otherwise, the drive may be damaged.
● While multi drives are installed in the same cabinet, enough space must be left for cooling fan.
● Drive cannot work over rated range. Otherwise, the drive may be damaged.
● While transporting the drive, please hold the firm case. If only hold the pre-cover, there is danger of drive main body falling,
injury or drive damage.
Cautions in use motor
● Different motor has different max allowable running speed. Motor can not run over the max allowable running speed.
● While drive is running at low speed, the motor auto-cool effect is seriously worse. If motor runs at low speed for long time, it
will be damaged for overheat. If needed, please use special motor for drive.
● While constant speed machinery runs at inconstant speed, there maybe sympathetic vibration. Please install vibration-proof
rubber under motor rack or use jumping frequency control function.
● While using frequency drive or working frequency power supply to drive, the torque characteristic are different. Please do
confirm the torque characteristic of the equipment connected.
● The rated current of diving motor is higher than that of standard motor, please confirm it and choose the right drive.
● While the wire between motor and drive is long, the max torque of the motor will reduce for voltage drop. So please use thick
cable while the distance between the motor and the drive is long.
3.2 Installation Environment
Installation environment is very important to the best use of this product for long time. Please install this product in the environment as the following table

Table 3-1: Environmental conditions required for reliable operation of AC10 series drives
● In order to improve the product stability, please do not use the drive where temperature changes sharply. While using in closed space such as control
cabinet, please use cooling fan or air-conditioning to cool drive to avoid temperature over limit range. Please also prevent drive from freeze, too low
temperature may cause components freeze fault.
● Derate according to the chart while over temperature limit.
AC10 Series Frequency Inverter Technical Manual
Requirement
Indoor without direct sunshine
-10 ～ +50℃
-30 ～ +60℃
<95%RH, no condensation
Please install the drive in place as follows:
● Place without oil mist, corrosive gases, flammable gas, dust or etc.
● Place without metal dust, oil, water or etc into drive (please do not install drive on flammable material such as food
and etc).
● Place without radioactive material or flammable material.
● Place without poisonous gases or liquid.
● Place with very little salification erosion.
● Place without direct sunshine.
<1000m, down power for use over 1000 meters
At 9 to 200 Hz, 5.9 m/s2 (0.6 g)
● Drive that can not be installed horizontally must be installed vertically.
● Please independently install high heating equipment such as braking resistor and etc which can not be installed in
the same cabinet with drive, installed at the air-in port of the drive is strictly prohibited.
