Safety Instructions
Instruction manual
Read the instruction manual first!
Handling the variable speed drive
Installation, commissioning, demounting, taking measure­ments, etc, of or on the variable speed drive may only be car­ried out by personnel technically qualified for the task. The installation must be carried out in accordance with local standards.
Opening the variable speed drive
WARNING: Always switch off the mains voltage before opening the variable speed drive and wait at least 5 minutes to allow the buffer capacitors to discharge.
Always take adequate precautions before opening the varia­ble speed drive. Although the connections for the control signals and the switches are isolated from the main voltage, do not touch the control board when the variable speed drive is switched on.
Precautions to be taken with a connected motor
If work must be carried out on a connected motor or on the driven machine, the mains voltage must always be discon­nected from the variable speed drive first. Wait at least 5 minutes before starting work.
Earthing
The variable speed drive must always be earthed via the mains safety earth connection.
Earth leakage current
This VSD has an earth leakage current which does exceeding
3.5 mA a.c. or 10 mA d.c. Therefore the minimum size of the protective earth conductor must comply with the local safety regulations for high leakage current equipment.
Residual current device (RCD) compatibility
This product cause a d.c. current in the protective conduc­tor. Where a residual current device (RCD) is used for pro­tection in case of direct or indirect contact, only a Type B RCD is allowed on the supply side of this product. Use RCD of 300 mA minimum.
EMC Regulations
In order to comply with the EMC Directive, it is absolutely necessary to follow the installation instructions. All installa­tion descriptions in this manual follow the EMC Directive.
Mains voltage selection
The variable speed drive is suitable for use with the mains voltage listed below. Adjustment of the mains voltage is not necessary!
380-415 V 380-480 V 440-525 V 500-690 V
Voltage tests (Megger)
Do not carry out voltage tests (Megger) on the motor, before all the motor cables have been disconnected from the varia­ble speed drive.
Condensation
If the variable speed drive is moved from a cold (storage) room to a room where it will be installed, condensation can occur. This can result in sensitive components becoming damp. Do not connect the mains voltage until all visible dampness has evaporated.
Incorrect connection
The variable speed drive is not protected against incorrect connection of the mains voltage, and in particular against connection of the mains voltage to the motor outlets U, V and W. The variable speed drive can be damaged in this way.
Power factor capacitors for improving
ϕ
cos
Remove all capacitors from the motor and the motor outlet.
Precautions during Autoreset
When the automatic reset is active, the motor will restart automatically provided that the cause of the trip has been removed. If necessary take the appropriate precautions.
Transport
To avoid damage, keep the variable speed drive in its original packaging during transport. This packaging is specially designed to absorb shocks during transport.
Emotron AB 01-3694-01r2 1
IT Mains supply
The variable speed drives can easily be connected to an IT mains supply, (non-earthed neutral), please contact your supplier for details.
Heat warning
Be aware of specific parts on the VSD having high temperature.
DC-link residual voltage
WARNING: After switching off the mains supply, dangerous voltage can still be present in the VSD. When opening the VSD for
installing and/or commissioning activities wait at least 5 minutes. In case of malfunction a qualified technician should check the DC-link or wait for one hour before dismantling the VSD for repair.

3. Installation
The description of installation in this chapter complies with the EMC standards and the Machine Directive.
Select cable type and screening according to the EMC requirements valid for the environment where the VSD is installed.
3.1 Before installation
Read the following checklist and think through your appli­cation before installation.
External or internal control.
Long motor cables (>100m).
Motors in parallel.
Functions.
Suitable VSD size in proportion to the motor/applica-
tion.
Mount separately supplied option boards according to
the instructions in the appropriate option manual.
If the VSD is temporarily stored before being connected, please check the technical data for environmental condi­tions. If the VSD is moved from a cold storage room to the room where it is to be installed, condensation can form on it. Allow the VSD to become fully acclimatised and wait until any visible condensation has evaporated before con­necting the mains voltage.
3.2 Cable connections
Dimension the cables and fuses in accordance with the nominal output current of the motor. See table 43, page
162.
Keep the motor cable between VSD and motor as short as possible.
The screening must be connected with a large contact surface of preferable 360× and always at both ends, to the motor housing and the VSD housing. When painted mounting plates are used, do not be afraid to scrape away the paint to obtain as large contact surface as possi­ble at all mounting points for items such as saddles and the bare cable screening. Relying just on the connection made by the screw thread is not sufficient.
NOTE: It is important that the motor housing has the same earth potential as the other parts of the machine.
• The litz connection is only necessary if the mounting plate is painted. All the variable speed drives have an unpainted back side and are therefore suitable for mounting on an unpainted mounting plate.
Connect the motor cables according to U - U, V - V and W - W.

3.2.1 Motor cables
To comply with the EMC emission standards the variable speed drive is provided with a RFI mains filter. The motor cables must also be screened and connected on both sides. In this way a so-called “Faraday cage” is created around the VSD, motor cables and motor. The RFI currents are now fed back to their source (the IGBTs) so the system stays within the emission levels.
Recommendations for selecting motor cables
Use screened cables according to specification in table 7. Use symmetrical shielded cable; three phase conductors and a concentric or otherwise symmetrically constructed PE conductor, and a shield.
When the conductivity of the cable shield is <50% of the conductivity of the phase conductor, a separate PE con­ductor is required.
Use heat-resistant cables, +60°C or higher.
Fig. 19
Switches between the motor and the VSD
If the motor cables are to be interrupted by maintenance switches, output coils, etc., it is necessary that the screening is continued by using metal housing, metal mounting plates, etc. as shown in the Fig. 21.
Fig. 22 shows an example when there is no metal mounting plate used (e.g. if IP54 variable speed drives are used). It is important to keep the “circuit” closed, by using metal hous­ing and cable glands.

Pay special attention to the following points:
If paint must be removed, steps must be taken to prevent subsequent corrosion. Repaint after making connections!
The fastening of the whole variable speed drive housing must be electrically connected with the mounting plate over an area which is as large as possible. For this purpose the removal of paint is necessary. An alternative method is to connect the variable speed drive housing to the mounting plate with as short a length of litz wire as pos­sible.
Try to avoid interruptions in the screening wherever pos­sible.

Placing of motor cables
Keep the motor cables as far away from other cables as possi­ble, especially from control signals. The minimum distance between motor cables and control cables is 30 cm.
Avoid placing the motor cables in parallel with other cables.
The power cables should cross other cables at an angle of 90°.
Long motor cables
If the connection to the motor is longer than 100 m (40 m for models 003-013), it is possible that capacitive current peaks will cause tripping at overcurrent. Using output coils can prevent this. Contact the supplier for appropriate coils.
Switching in motor cables
Switching in the motor connections is not advisable. In the event that it cannot be avoided (e.g. emergency or mainte­nance switches) only switch if the current is zero. If this is not done, the VSD can trip as a result of current peaks.
3.2.2 Mains cables
Dimension the mains and motor cables according to local regulations. The cable must be able to carry the VSD load current.
Recommendations for selecting mains cables
To fulfil EMC purposes it is not necessary to use screened mains cables.
Use heat-resistant cables, +60°C or higher.
Dimension the cables and fuses in accordance with local regulations and the nominal output current of the motor. See table 43, page 162.
The litz connection is only necessary if the mounting plate is painted. All the variable speed drives have an unpainted back side and are therefore suitable for mounting on an unpainted mounting plate.
Connect the mains cables according to Fig. 23. The VSD has a built-in RFI mains filter that complies with category C3 which suits the Second Environment standard.

3.6 Thermal protection on the motor
Standard motors are normally fitted with an internal fan. The cooling capacity of this built-in fan is dependent on the frequency of the motor. At low frequency, the cooling capac­ity will be insufficient for nominal loads. Please contact the motor supplier for the cooling characteristics of the motor at lower frequency.
WARNING: Depending on the cooling characteristics of the motor, the application, the speed and the load, it may be necessary to use forced cooling on the motor.
Motor thermistors offer better thermal protection for the motor. Depending on the type of motor thermistor fitted, the optional PTC input may be used. The motor thermistor gives a thermal protection independent of the speed of the motor, thus of the speed of the motor fan. See the functions, Motor I

t type [231] and Motor I2t current [232].
3.7 Motors in parallel
It is possible to have motors in parallel as long as the total current does not exceed the nominal value of the VSD. The following has to be taken into account when setting the motor data:

NOTE: The screening of control signal cables is necessary to comply with the immunity levels given in the EMC Directive (it reduces the noise level).
NOTE: Control cables must be separated from motor and mains cables.
26 Control Connections Emotron AB 01-3694-01r2
4.5.2 Types of control signals
Always make a distinction between the different types of sig­nals. Because the different types of signals can adversely affect each other, use a separate cable for each type. This is often more practical because, for example, the cable from a pressure sensor may be connected directly to the variable speed drive.
We can distinguish between the following types of control signals:
4.5.4 Single-ended or double-ended
connection?
In principle, the same measures applied to motot cables must be applied to all control signal cables, in accordance with the EMC-Directives.
For all signal cables as mentioned in section 4.5.2 the best results are obtained if the screening is connected to both ends. See Fig. 30.
Analogue inputs
Voltage or current signals, (0-10 V, 0/4-20 mA) normally used as control signals for speed, torque and PID feedback signals.
Analogue outputs
Voltage or current signals, (0-10 V, 0/4-20 mA) which change slowly or only occasionally in value. In general, these are control or measurement signals.
Digital
Voltage or current signals (0-10 V, 0-24 V, 0/4-20 mA) which can have only two values (high or low) and only occa­sionally change in value.
Data
Usually voltage signals (0-5 V, 0-10 V) which change rapidly and at a high frequency, generally data signals such as RS232, RS485, Profibus, etc.
Relay
Relay contacts (0-250 VAC) can switch highly inductive loads (auxiliary relay, lamp, valve, brake, etc.).

Example:
The relay output from a variable speed drive which controls an auxiliary relay can, at the moment of switching, form a source of interference (emission) for a measurement signal from, for example, a pressure sensor. Therefore it is advised to separate wiring and screening to reduce disturbances.
4.5.3 Screening
For all signal cables the best results are obtained if the screening is connected to both ends: the VSD side and the at the source (e.g. PLC, or computer). See Fig. 30.
It is strongly recommended that the signal cables be allowed to cross mains and motor cables at a 90° angle. Do not let the signal cable go in parallel with the mains and motor cable.
