Chapter 3 Product overview

3.1 What this chapter contains

This chapter mainly introduces the operation principles, product features, layouts, nameplates and

model instructions.

3.2 Basic principle

Goodrive350 series inverter is used to control asynchronous AC induction motor and

permanent-magnet synchronous motor. The figure below shows the main circuit diagram of the

inverter. The rectifier converts

3PH AC voltage into DC voltage, and the capacitor bank of

intermediate circuit stabilizes the DC voltage. The inverter converts DC voltage into the AC voltage

used by AC motor. When the circuit voltage exceeds the max. limit value, external brake resistor will

be connected to intermediate DC circuit to consume the feedback energy.

Chapter 4 Installation guide

4.1 What this chapter contains

This chapter introduces the mechanical and electrical installations of the inverter.

 Only well trained and qualified professionals are allowed to carry out the

operations mentioned in this chapter. Please carry out operations according

to instructions presented in Safety precautions. Ignoring these safety

precautions may lead to physical injury or death, or device damage.

 Ensure the inverter power is disconnected before installation. If the inverter

has been powered on, disconnect the inverter and wait for at least the time

designated on the inverter, and ensure the POWER indicator is off. Users are

recommended to use a multimeter to check and ensure the inverter DC bus

voltage is below 36V.

 Installation must be designed and done according to applicable local laws

and regulations. INVT does not assume any liability whatsoever for any

installation which breaches local laws and regulations. If recommendations

given by INVT are not followed, the inverter may experience problems that

the warranty does not cover.

4.2 Mechanical installation

4.2.1 Installation environment

Installation environment is essential for the inverter to operate at its best in the long run. The

installation environment of the inverter should meet the following requirements.

Environment

Condition

Installation

Indoors

site

 -10-+50°C;

 When the ambient temperature exceeds 40°C, derate 1% for every

additional 1°C;

 It is not recommended to use the inverter when the ambient temperature

is above 50°C;

 In order to improve reliability, do not use the inverter in cases where the

Ambient

temperature changes rapidly;

temperature

 When the inverter is used in a closed space eg control cabinet, use

cooling fan or air conditioner to prevent internal temperature from

exceeding the temperature required;

 When the temperature is too low, if restart an inverter which has been

idled for a long time, it is required to install external heating device before

use to eliminate the freeze inside the inverter, failing to do so may cause

damage to the inverter.

Humidity

 The relative humidity (RH) of the air is less than 90%;

Chapter 4

Environment

Condition

 Condensation is not allowed;

 The max RH cannot exceed 60% in the environment where there are

corrosive gases.

Storage

temperature

The installation site should meet the following requirements.

 Away from electromagnetic radiation sources;

 Away from oil mist, corrosive gases and combustible gases;

 Ensure foreign object like metal powder, dust, oil and water will not fall

Running

into the inverter (do not install the inverter onto combustible object like

environment

wood);

 Away from radioactive substance and combustible objects;

 Away from harmful gases and liquids;

 Low salt content;

 No direct sunlight

 Below 1000m;

 When the altitude exceeds 1000m, derate 1% for every additional 100m;

Altitude

 When the altitude exceeds 2000m, configure isolation transformer on the

input end of the inverter. It is recommended to keep the altitude below

5000m.

Vibration

The max. amplitude of vibration should not exceed 5.8m/s² (0.6g)

Installation

Install the inverter vertically to ensure good heat dissipation effect

direction

Note:

1. GD350 series inverter should be installed in a clean and well-ventilated environment based

on the IP level.

2. The cooling air must be clean enough and free from corrosive gases and conductive dust.

4.2.2 Installation direction

The inverter can be installed on the wall or in a cabinet.

The inverter must be installed vertically. Check the installation position according to following

requirements. See appendix C Dimension drawings for detailed outline dimensions.

4.2.3 Installation mode

There are three kinds of installation modes based on different inverter dimensions.

1. Wall-mounting: suitable for 380V 315kW and below inverters, and 660V 355kW and below

inverters;

2. Flange-mounting: suitable for 380V 200kW and below inverters, and 660V 220kW and below

inverters;

3. Floor-mounting: suitable for 380V 220-500kW inverters, and 660V 250-630kW inverters.

Wall-mounting

Flange-mounting

Fig 4.2 Installation mode

(1) Mark the position of the installation hole. See appendix for the position of installation hole;

(2) Mount the screws or bolts onto the designated position;

(3) Put the inverter on the wall;

(4) Tighten the fixing screws on the wall.

Note:

Flange-mounting plate is a must for 380V 1.5-75kW inverters that adopt flange-mounting

mode; while 380V 90-200kW and 660V 22-220kW models need no flange-mounting plate.

Optional installation base is available for 380V 220-315kW and 660V 250-355kW inverters.

The base can hold an input AC reactor (or DC reactor) and an output AC reactor.

4.5 Wiring protection

4.5.1 Protect the inverter and input power cable in short-circuit

Protect the inverter and input power cable during short-circuit to avoid thermal overload.

Carry out protective measures according to the following requirements.

Inverter

Input cable

M3 ~

Fuse

Fig 4.22 Fuse configuration

Note: Select the fuse according to operation manual. During short-circuit, the fuse will protect

input power cables to avoid damage to the inverter; when internal short-circuit occurred to the

inverter, it can protect neighboring equipment from being damaged.

4.5.2 Protect the motor and motor cable in short circuit

If the motor cable is selected based on rated inverter current, the inverter will be able to protect the

motor cable and motor during short circuit without other protective devices.

 If the inverter is connected to multiple motors, it is a must to use a separated

thermal overload switch or breaker to protect the cable and motor, which may

require the fuse to cut off the short circuit current.

4.5.3 Protect motor and prevent thermal overload

According to the requirements, the motor must be protected to prevent thermal overload. Once

overload is detected, users must cut off the current. The inverter is equipped with motor thermal

overload protection function, which will block output and cut off the current (if necessary) to protect

the motor.

Chapter 4

4.5.4 Bypass connection

In some critical occasions, industrial frequency conversion circuit is necessary to ensure proper

operation of the system when inverter fault occurs.

In some special cases, eg, only soft startup is needed, it will converts to power-frequency operation

directly after soft startup, corresponding bypass link is also needed.

 Do not connect any power source to inverter output terminals U, V and W. The

voltage applied to motor cable may cause permanent damage to the inverter.

If frequent switch-over is needed, users can use the switch which carries mechanical interlock or a

contactor to ensure motor terminals will not be connected to input power cables and inverter output

ends simultaneously.
