D.3 Power supply

Refer to the electrical installation.

 Ensure that the voltage class of the inverter is consistent with that of the

grid.

D.4 Cables

D.4.1 Power cables

The sizes of the input power cables and motor cables must meet the local regulation.

•

The input power cables and motor cables must be able to carry the corresponding load currents.

•

The maximum temperature margin of the motor cables in continuous operation cannot be lower

than 70°C.

•

The conductivity of the PE grounding conductor is the same as that of the phase conductor, that

is, the cross-sectional areas are the same.

•

For details about the EMC requirements, see Appendix B "Technical data."

To meet the EMC requirements stipulated in the CE standards, you must use symmetrical shielded

cables as motor cables (as shown in the following figure).

Four-core cables can be used as input cables, but symmetrical shielded cables are recommended.

Compared with four-core cables, symmetrical shielded cables can reduce electromagnetic radiation

as well as the current and loss of the motor cables.

shield layer

Shield layer

Conductor

Jacket

Insulator

Note: If the conductivity of the shield layer of the motor cables cannot meet the requirements,

separate PE conductors must be used.

To protect the conductors, the cross-sectional area of the shielded cables must be the same as that of

the phase conductors if the cable and conductor are made of materials of the same type. This

reduces grounding resistance, and thus improves impedance continuity.

To effectively restrict the emission and conduction of radio frequency

(RF) interference, the

conductivity of the shielded cable must at least be 1/10 of the conductivity of the phase conductor.

This requirement can be well met by a copper or aluminium shield layer. The following figure shows

the minimum requirement on motor cables of an inverter. The cable must consist of a layer of

spiral-shaped copper strips. The denser the shield layer is, the more effectively the electromagnetic

-322-

Appendix D

interference is restricted.

Insulating layer

Shield layer

Cross-section of the cable

D.4.2 Control cables

All analog control cables and cables used for frequency input must be shielded cables. Analog signal

cables need to be double-shielded twisted-pair cables (as shown in figure a). Use one separate

shielded twisted pair for each signal. Do not use the same ground wire for different analog signals.

Multiple double-shielded twisted-pair cables

Multiple shielded twisted-pair cables

Power cable arrangement

For low-voltage digital signals, double-shielded cables are recommended, but shielded or unshielded

twisted pairs (as shown in figure b) also can be used. For frequency signals, however, only shielded

cables can be used.

Relay cables need to be those with metal braided shield layers.

Keypads need to be connected by using network cables. In complicated electromagnetic

environments, shielded network cables are recommended.

Note: Analog signals and digital signals cannot use the same cables, and their cables must be

arranged separately.

Do not perform any voltage endurance or insulation resistance tests, such as high-voltage insulation

tests or using a megameter to measure the insulation resistance, on the inverter or its components.

Insulation and voltage endurance tests have been performed between the main circuit and chassis of

each inverter before delivery. In addition, voltage limiting circuits that can automatically cut off the test

voltage are configured inside the inverters.

Note: Check the insulation conditions of the input power cable of an inverter according to the local

regulations before connecting it.

Note:

1. Cables of the sizes recommended for the main circuit can be used in scenarios where the

ambient temperature is lower than 40°C, the wiring distance is shorter than 100 m, and the

current is the rated current.

2. The terminals P1, (+), and (-) are used to connect to DC reactors and brake accessories.

D.4.3 Cable arrangement

Motor cables must be arranged away from other cables. The motor cables of several inverters can be

arranged in parallel. It is recommended that you arrange the motor cables, input power cables, and

control cables separately in different trays. The output dU/dt of the inverters may increase

electromagnetic interference on other cables. Do not arrange other cables and the motor cables in

parallel.

If a control cable and power cable must cross each other, ensure that the angle between them is 90

degrees.

The cable trays must be connected properly and well grounded. Aluminum trays can implement local

equipotential.

The following figure shows the cable arrangement distance requirements.

D.4.4 Insulation inspection

Check the motor and the insulation conditions of the motor cable before running the motor.

1. Ensure that the motor cable is connected to the motor, and then remove the motor cable from the

U, V, and W output terminals of the inverter.

2. Use a megameter of 500 V DC to measure the insulation resistance between each phase

conductor and the protection grounding conductor. For details about the insulation resistance of

the motor, see the description provided by the manufacturer.

Note: The insulation resistance is reduced if it is damp inside the motor. If it may be damp, you

need to dry the motor and then measure the insulation resistance again.

D.5 Breaker and electromagnetic contactor

You need to add a fuse to prevent overload.

You need to configure a manually manipulated molded case circuit breaker (MCCB) between the AC

power supply and inverter. The breaker must be locked in the open state to facilitate installation and

inspection. The capacity of the breaker needs to be 1.5 to 2 times the rated current of the inverter.

 According to the working principle and structure of breakers, if the

manufacturer's regulation is not followed, hot ionized gases may escape

from the breaker enclosure when a short-circuit occurs. To ensure safe use,

exercise extra caution when installing and placing the breaker. Follow the

manufacturer's instructions.

To ensure safety, you can configure an electromagnetic contactor on the input side to control the

switch-on and switch-off of the main circuit power, so that the input power supply of the inverter can

be effectively cut off when a system fault occurs.

D.6 Reactors

When the voltage of the grid is high, the transient large current that flows into the input power circuit

may damage rectifier components. You need to configure an AC reactor on the input side, which can

also improve the current adjustment coefficient on the input side.

When the distance between the inverter and motor is longer than 50 m, the parasitic capacitance

between the long cable and ground may cause large leakage current, and overcurrent protection of

the inverter may be frequently triggered. To prevent this from happening and avoid damage to the

motor insulator, compensation must be made by adding an output reactor. When an inverter is used

to drive multiple motors, take the total length of the motor cables (that is, sum of the lengths of the

motor cables) into account. When the total length is longer than 50 m, an output reactor must be

added on the output side of the inverter. If the distance between the inverter and motor is 50 m to 100

m, select the reactor according to the following table. If the distance is longer than 100 m, contact

INVT's technical support technicians.

DC reactors can be directly connected to inverters of 380 V, 132 kW or higher and the 660 V series.

DC reactors can improve the power factor, avoid damage to bridge rectifiers caused due to large input

current of the inverter when large-capacity transformers are connected, and also avoid damage to the

rectification circuit caused due to harmonics generated by grid voltage transients or phase-control

loads.

D.8 Brake system

D.8.1 Brake component selection

When an inverter driving a high-inertia load decelerates or needs to decelerate abruptly, the motor

runs in the power generation state and transmits the load-carrying energy to the DC circuit of the

inverter, causing the bus voltage of the inverter to rise. If the bus voltage exceeds a specific value, the

inverter reports an overvoltage fault. To prevent this from happening, you need to configure brake

components.

 The design, installation, commissioning, and operation of the device must be

performed by trained and qualified professionals.

 Follow all the "Warning" instructions during the operation. Otherwise, major

physical injuries or property loss may be caused.

 Only qualified electricians are allowed to perform the wiring. Otherwise,

damage to the inverter or brake components may be caused.

 Read the brake resistor or unit instructions carefully before connecting them

to the inverter.

 Connect brake resistors only to the terminals PB and (+), and brake units

only to the terminals (+) and (-). Do not connect them to other terminals.

Otherwise, damage to the brake circuit and inverter and fire may be caused.

 Connect the brake components to the inverter according to the wiring

diagram. If the wiring is not properly performed, damage to the inverter or

other devices may be caused.

D.8.1.1 Brake units for AC 3PH 380V (-15%)-440V (+10%)

Goodrive350 series inverters of 380 V, 37 kW or lower are equipped with built-in brake units, and

those of 380 V, 45 kW or higher need to be configured with external brake units. Inverters of 45 kW to

110 kW can be configured with optional built-in brake units, and after a built-in brake unit is configured,

the inverter model is added with a suffix "-B", for example, GD350-045G-4-B. Select brake resistors

according to the specific requirements (such as the brake torque and brake usage requirements) on

site.

Appendix E STO function description

Reference standards: IEC 61508-1, IEC 61508-2, IEC 61508-3, IEC 61508-4, IEC 62061, ISO

13849-1, and IEC 61800-5-2

You can enable the safe torque off (STO) function to prevent unexpected startups when the main

power supply of the drive is not switched off. The STO function switches off the drive output by turning

off the drive signals to prevent unexpected startups of the motor (see the following figure). After the

STO function is enabled, you can perform some-time operations (such as non-electrical cleaning in

the lathe industry) and maintain the non-electrical components of the device without switching off the

drive.

E.3 STO function installation checklist

Before installing the STO, check the items described in the following table to ensure that the STO

function can be properly used.

Item

□

Ensure that the drive can be run or stopped randomly during commissioning.

Stop the drive (if it is running), disconnect the input power supply, and isolate the drive

□

from the power cable through the switch.

□

Check the STO circuit connection according to the circuit diagram.

Check whether the shielding layer of the STO input cable is connected to the +24 V

□

reference ground COM.

□

Connect the power supply.

Test the STO function as follows after the motor stops running:

•

If the drive is running, send a stop command to it and wait until the shaft of the

motor stops rotating.

□

•

Activate the STO circuit and send a start command to the drive. Ensure that the

motor does not start.

•

Deactivate the STO circuit.

□

Restart the drive, and check whether the motor is running properly.

Test the STO function as follows when the motor is running:

•

Start the drive. Ensure that the motor is running properly.

•

Activate the STO circuit.

□

•

The drive reports an STO fault (for details, see section 7.5 "Inverter faults and

corresponding solutions"). Ensure that the motor coasts to stop rotating.

•

Deactivate the STO circuit.

□

Restart the drive, and check whether the motor is running properly.
