3 Product Overview
3.1 What this chapter contains
The chapter briefly describes the operation principle, product characteristics, layout, na e
plate and type designation infor ation.
3.2 Basic principles
MSI200A series inverters are wall, flange and ountable devices for controlling asynchronous
AC inductance otors.
The diagra below shows the ain circuit diagra of the inverter. The rectifier converts three-
phase AC voltage to DC voltage. The capacitor bank of the inter ediate circuit stabilizes the
DC voltage. The converter transfor s the DC voltage back to AC voltage for the AC otor.
The brake pipe connects the external braking resistor to the inter ediate DC circuit to
consu e the feedback energy when the voltage in the circuit exceeds its axi u li it.
Diagra 3-1 The ain circuit diagra (≤30kW)
Diagra 3-2 The ain circuit diagra (≥37kW)
Note:
1. The inverter above 37kW (including 37kW) supports external DC reactor which is an
optional part. Before connecting, it is necessary to re ove the copper row between P1 and
（+）.
2. The inverters (≤30kW) have standard e bedded 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.

4 Installation Guidelines
4.1 What this chapter contains
The chapter describes the echanical 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 ay cause physical injury or death or da age to the devices.
 Ensure the power supply of the inverter is disconnected during the operation.
Wait for at least the ti e designated until the POWER indicator is off after the
disconnection if the power supply is applied. It is reco ended to use the
ulti eter to onitor that the DC bus voltage of the drive is under 36V.
 The installation and design of the inverter should be co plied with the
require ent of the local laws and regulations in the installation site. If the
installation infringes the require ent, our co pany will exe pt fro any
responsibility. Additionally, if users do not co ply with the suggestion, so e
da age beyond the assured aintenance range ay occur.
4.2 Mechanical installation
4.2.1 Installation environment
The installation environ ent is i portant for a full perfor ance and long-ter stable functions
of the inverter. Check the installation environ ent as followings:
Environment Conditions
Installation site Indoor
Environ ent
te perature
-10~+50℃
If the a bient te perature of the inverter is above 40J, derate 3%
for every additional 1J.
It is not reco ended to use the inverter if the a bient
te perature is above 50J.
In order to i prove the reliability of the device, do not use the
inverter if the a bient te perature changes frequently.
Please provide cooling fan or air conditioner to control the internal
a bient te perature below the required one if the inverter is used
in a close space such as in the control cabinet.
When the te perature 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 te perature, otherwise da age to
the devices ay occur.
