Product Overview 3
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
TETA MA610 series inverters are wall, flange and 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 )
Note:
Diagram 3-2 The main circuit diagram (≥37kW )
1. The inverter above 37kW (including 37kW) supports external DC reactor which is an
optional part. Before connecting, it is necessary to remove the copper row between P1 and
（+）.
2. The inverters (≤30kW ) havestandard 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.

Side cover
Optional part. The side cover will increase the
protective degree of the inverter. The internal
temperature of the inverter will increase, too, so it is
necessary to derate the inverter at the same time

Environment
temperature
-10~+50℃
If the ambient temperature of the inverter is above 40℃, derate 3%
for every additional 1℃.
It is not recommendedto use the inverter if the ambient
temperature is above 50℃.
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 necessaryto provide an external heating
device to increase the internal temperature, otherwise damage
to
the devices may occur.
Humidity
RH≤90%
No condensation is allowed.
Installation Guidelines 4
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 m ay cause physical injury or death or dam age 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
damagebeyond the assured maintenancerange 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:

13
Note:
TETA MA610 series 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
Environment
Conditions
The maximum relative humility should be equal to or less than
60% in corrosive air.
Storage
temperature
-30~+60℃
Running
environment
condition
The installation site of the inverter should:
keep away from the electromagnetic radiation source;
keep away from contaminative air, such as corrosive gas, oil mist
and flammablegas;
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);
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.

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 Installationmanner
(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.
(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,
which the flange installation of 37~200kW inverters does not need the installation bracket.
2. 220~315kW inverters need optional base in the floor installation.
4.2.4 Multiple installations
Parallel installation
Note:
Fig 4-3 Parallel installation
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
Fig 4-4 Vertical installation
Note: W indscreen 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.
