Safety Instructions

Instruction manual
Read this instruction manual before using the Variable
Speed Drive, VSD.
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
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 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 variable speed drive has an earth leakage current which
does exceed 3.5 mA AC. Therefore the minimum size of the
protective earth conductor must comply with the local safety
regulations for high leakage current equipment which means
that according the standard IEC61800-5-1 the protective
earth connection must be assured by one of following condi-
tions:
1. Use a protective conductor with a cable cross-section of
2
at least 10 mm for copper (Cu) or 16 mm
ium (Al).
2. Use an additional PE wire, with the same cable cross-sec-
tion as the used original PE and mains supply wiring.

Residual current device (RCD)
compatibility
This product cause a DC 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 may be ordered for use with the
mains voltage range listed below.
VFX40/48: 230-480 V
VFX50/52: 440-525 V
VFX69: 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
cos
Remove all capacitors from the motor and the motor outlet.
Precautions during Autoreset
2
for alumin-
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.
