Install a magnetic ring to the U, V, and W output cables at the
drive side and wind the cables through the magnetic ring for two
to four turns.
8
Use shielded power cables with the shield grounded properly.
This section takes feeding of punch press as an example to describe a typical application
of electrical design of the AC drive.
Basic information
Basic information of the AC drive
● : Voltage of three-phase 380 V to 480 V; power of 2.2 kW; braking resistor required
● Application: Inovance PLC+HMI; RS485 communication
● I/O requirements: Four DIs to control start/stop and forward/reverse running; reset
upon fault; speed adjustment by external potentiometer connecting to AI
Electrical cabinet schematic diagram
The following figure shows the schematic diagram of the electrical cabinet based on the

5.1 Installation Preparation
5.1.1 Installation Environment Requirements
Table 5–1 Environment requirements
Environment Conditions
Installation location Indoors without direct sunlight, dust, corrosive gas, combustible
gas, oil mist, water vapor, drip, or salt
Overvoltage category
of the power grid
Overvoltage category Ⅲ
Temperature
Installation/Operating temperature: –10°C to +50°C. When the
temperature ranges from –10°C to +40°C, no derating is
required. For temperature above 40°C, derate 1.5% for every
additional 1°C.
Storage/Transportation temperature: -20°C to +60°C.
● For better reliability, use the product in places without drastic
temperature change.
● When installing the drive in an enclosed cabinet, use the
cooling fan or air conditioner to keep the incoming air
temperature below 50ºC. Failure to comply will result in
overheat or fire.
● Install the drive on a flame-retardant surface, with sufficient
clearance reserved for heat dissipation.
● Take measures to prevent the drive from being frozen.
Humidity Storage/Ambient humidity: <95% RH, non-condensing
Environment
Pollution degree 2 or below
Install the drive in a place that meets the following
requirements:
● Free from direct sunlight, dust, corrosive gas, combustible or
explosive gas, oil mist, water vapor, drip, or salt
● Not prone to vibration and away from equipment that may
generate strong vibration, such as a punch press
● Free from unwanted objects such as metallic dust, oil, and
water that may enter the drive
● Free from radioactive materials, combustible materials,
hazardous gas and liquid, and salt corrosion
● Away from combustible materials such as wood
● The mounting base plate must be free from oil and grease. Do
not use tapping oil or liquid thread locker.
