3.1 What this chapter contains
The chapter briefly describes the operation principle, product characteristics, layout, name plate and type
designation information.
3.2 Basic principles
CV50 inverters are wall and flange mountable devices for controlling asynchronous AC inductance motors.
The diagram below shows the main circuit diagram of the inverter. The rectifier converts three-phase AC
voltage to DC voltage. The capacitor bank of the intermediate circuit stabilizes the DC voltage. The converter
transforms the DC voltage back to AC voltage for the AC motor. The brake pipe connects the external braking
resistor to the intermediate DC circuit to consume the feedback energy when the voltage in the circuit exceeds
its maximum limit.
Diagram 3-1 The main circuit diagram (30kW)
Diagram 3-2 The main circuit diagram (37kW)
Note:
1. The inverter above 37kW (including 37kW)supports external DC reactor. Before connecting, it is necessary
to remove the copper row between P1 and（+）.
2. The inverters (≤30kW) have standard embedded braking units and the braking resistor is optional.
3.The inverters (≥37kW) can be installed with optional braking units and the braking unit and resistor are
optional.

16 - 144 Installation Guidelines
4 Installation Guidelines
4.1 What this chapter contains
The chapter describes the mechanical installation and electric installation.
Only qualified electricians are allowed to carry out what described in this chapter. Please
operate as the instructions in Safety Precautions. Ignoring these may cause physical
injury or death or damage to the devices.
Ensure the power supply of the inverter is disconnected during the operation. Wait for at
least the time designated until the POWER indicator is off after the disconnection if the
power supply is applied. It is recommended to use the multimeter to monitor that the DC
bus voltage of the drive is under 36V.
The installation and design of the inverter should be complied with the requirement of the
local laws and regulations in the installation site. If the installation infringes the
requirement, our company will exempt from any responsibility. Additionally, if users do not
comply with the suggestion, some damage beyond the assured maintenance range may
occur.
4.2 Mechanical installation
4.2.1 Installation environment
The installation environment is important for a full performance and long-term stable functions of the inverter.
Check the installation environment as followings:
Environment Conditions
Installation site Indoor
Environment
temperature
-10~+50ºC
If the ambient temperature of the inverter is above 40ºC, derate 3% for every additional
1ºC.
It is not recommended to use the inverter if the ambient temperature is above 50ºC.
In order to improve the reliability of the device, do not use the inverter if the ambient
temperature changes frequently.
Please provide cooling fan or air conditioner to control the internal ambient
temperature below the required one if the inverter is used in a close space such as
in the control cabinet.
When the temperature is too low, if the inverter needs to restart to run after a long
stop, it is necessary to provide an external heating device to increase the internal
temperature, otherwise damage to the devices may occur.
Humidity

environment
condition
The installation site of the inverter should:
- Keep away from an electromagnetic radiation source
- Keep away from contaminative air, such as corrosive gas, oil mist and flammable gas
- Ensure foreign objects, such as metal power, dust, oil. Water can not enter into the
inverter (do not install the inverter on the flammable materials such as wood)

Installation Guidelines 17 - 144
Environment Conditions
- Keep away from direct sunlight, oil mist, steam and vibration environment.
Altitude Below 1000m
If the sea level is above 1000m, please derate 1% for every additional 100m.
Vibration ≤5.8m/s2(0.6g)
Installation
direction
The inverter should be installed on an upright position to ensure sufficient cooling
effect.
Note:
CV50 inverters should be installed in a clean and ventilated environment according to enclosure classification.
Cooling air must be clean, free from corrosive materials and electrically conductive dust.
4.2.2 Installation direction
The inverter may be installed on the wall or in a cabinet.
The inverter must be installed in an upright position. Check the installation site according to the requirements
below. Refer to chapter Dimension Drawings in the appendix for frame details.
Fig 4-1 Installation direction of the inverter
4.2.3 Installation manner
The inverter can be installed in two different ways, depending on the frame size:
a) Wall mounting (for the inverter 315kW)
b) Flange mounting (for the inverter 200kW). Some need optional flange installation board.
c) Floor mounting (220kW the inverter 500kW). Some need optional base.
Fig 4-2 Installation manner
(1) Mark the hole location. The location of the holes is shown in the dimension drawings in the appendix.
(2) Fix the screws or bolts to the marked locations.
(3) Position the drive onto the wall.

18 - 144 Installation Guidelines
(4) Tighten the screws in the wall securely.
Note:
1. The flange installation bracket is needed in the flange installation of 1.5~30kW inverters, while the flange
installation of 37~200kW inverters does not need the installation bracket.
2. 220~315kW inverters need optional base in the floor installation.

Note:
Before installing the different sizes inverters, please align their top position for the convenience of later
maintenance.
The minimum space of B, D and C is 100mm.
4.2.5 Vertical installation

Installation Guidelines 19 - 144
Note: Windscreen should be added in vertical installation for avoiding mutual impact and insufficient cooling.
4.2.6 Tilt installation
Fig 4-5 Tilt installation
Note: Ensure the separation of the wind input and output channels in tilt installation for avoiding mutual impact.

Note:
The circuit breaker, DC reactor, braking unit, braking resistor, input reactor, input filter and output
filters are optional parts. Please refer to Peripheral Optional Parts for detailed information.
P1 and (+) are short circuited in factory, if need to connect with a DC rector, please remove the contact

tag between P1 and (+).
Before connecting the braking resistor cable, remove the yellow labels of PB, (+), and (-) from the
terminal blocks. Otherwise, poor connection may occur.
