Safety Instructions
Instruction manual
Read the instruction manual first!
Handling the variable speed drive
Installation, commissioning, demounting, taking measure-
ments, etc, of or on the variable speed drive may only be car-
ried out by personnel technically qualified for the task. The
installation must be carried out in accordance with local
standards.
Opening the variable speed drive
Always take adequate precautions before opening the varia-
ble 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 discon-
nected 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 conduc-
tor. Where a residual current device (RCD) is used for pro-
tection 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 installa-
tion 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 varia-
ble 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
cosϕ
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.
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.

2Emotron AB 01-3694-01r2
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
DC-link residual voltage
Be aware of specific parts on the VSD having
high temperature.
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.

Before mounting it is recommended that the installation is
planned out first.
• Be sure that the VSD suits the mounting location.
• The mounting site must support the weight of the VSD.
• Will the VSD continuously withstand vibrations and/or
shocks?
• Consider using a vibration damper.
• Check ambient conditions, ratings, required cooling air
flow, compatibility of the motor, etc.
• Know how the VSD will be lifted and transported.

2.2.1 Cooling
Fig. 6 shows the minimum free space required around the
VSD for the models 003 to 250 in order to guarantee ade-
quate cooling. Because the fans blow the air from the bot-
tom to the top it is advisable not to position an air inlet
immediately above an air outlet.
The following minimum separation between two variable
speed drives, a VSD and a non-dissipating wall must be
maintained:

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 appli-
cation 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 condi-
tions. 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 con-
necting the mains voltage.
3.2 Cable connections
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 con-
ductor is required.
• Use heat-resistant cables, +60°C or higher.
• 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 possi-
ble 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.
• 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.
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 hous-
ing and cable glands.
NOTE: It is important that the motor housing has the
same earth potential as the other parts of the machine.
