■General warning
The voltage of the frequency converter
is dangerous whenever the converter is
connected to mains. Incorrect fitting of the
motor or frequency converter may cause damage to the
equipment, serious injury or death. Consequently, it is
essential to comply with the instructions in this manual
as well as local and national rules and safety regulations.
1. The VLT frequency converter must be disconnected
from mains if repair work is to be carried out. Check
that the mains supply has been disconnected
and that the necessary time has passed before
removing motor and mains plugs.
2. The [STOP/RESET] or [OFF/STOP] key on the
control panel of the VLT frequency converter does
not disconnect the equipment from mains and is
thus not to be used as a safety switch.
3. Correct protective earthing of the equipment
must be established, the user must be protected
against supply voltage, and the motor must be
protected against overload in accordance with
applicable national and local regulations.
4. The earth leakage currents are higher than 3.5 mA.
5. Protection against motor overload is not included
in the factory setting. If this function is desired, set
parameter 128 to data value ETR trip or data value
ETR warning. On VLT 6000, set parameter 117 to
data value ETR trip or data value ETR warning.
Note: The function is initialised at 1.16 x
rated motor current and rated motor frequency
(see Operating manual).
For the North American market: The ETR
functions provide class 20 motor overload
protection in accordance with NEC.
6. Do not remove the plugs for the motor and
mains supply while the VLT frequency converter
is connected to mains. Check that the mains
supply has been disconnected and that the
necessary time has passed before removing
motor and mains plugs.
7. Please note that the VLT frequency converter has
more voltage inputs than L1, L2 and L3, when
loadsharing (linking of DC intermediate circuit) and
external 24 V DC have been installed. Check
that all voltage inputs have been disconnected
and that the necessary time has passed before
repair work is commenced.
■Warning against unintended start
1. The motor can be brought to a stop by
means of digital commands, bus commands,
references or a local stop, while the frequency
converter is connected to mains. If personal
safety considerations make it necessary to
ensure that no unintended start occurs, these
stop functions are not sufficient.
2. While parameters are being changed, the
motor may start. Consequently, the stop key
[STOP/RESET] or [OFF/STOP] must always be
activated, following which data can be modified.
3. A motor that has been stopped may start if faults
occur in the electronics of the frequency converter,
or if a temporary overload or a fault in the supply
mains or the motor connection ceases.
176FA055.11
Warning:
Touching the electrical parts may be fatal - even after the
equipment has been disconnected from mains.
Also make sure that other voltage inputs have been disconnected,
such as external 24 V DC, load-sharing (linkage of DC intermediate
circuit), as well as the motor connection for kinetic back-up.
Using VLT 5300-5500 / 6350-6550 /8350-8550:
wait at least 15 minutes

A qualified person with a forklift or other similar
lifting device will be needed to remove the VLT
frequency converter from the crate.
To open the crate:
•Remove the metal locking tabs that secure the top
panel of the crate, this will give access to the lifting
rings on the top of the VLT frequency converter.
•On IP 00 versions remove the supporting
brace bolted to the lifting rings.
•A forklift or similar lifting device should be
used at this time to ensure the stability of the
VLT frequency converter while the rest of the

■Pre-installation
The most important part of the mechanical
instal-lation is the pre-installation planning. Neglecting
this planning may very well result in extra work
during and after the installation
Before you install your VLT frequency converter you
should select the best possible operational site.
Consider the following in the pre-installation plan:
•Ambient operating temperature.
•Installation method.
•The position of the VLT frequency converter.
•The cable routing.
•Ensure that the power source supplies the
correct voltage and necessary current.
•If the VLT frequency converter is without
built-in mains disconnector and fuses, ensure
that the external disconnector or fuses have
the correct current rating.
■Installation site
The VLT frequency converter must be
installed vertically.
The VLT frequency converter is cooled by means of
air circulation. For the unit to be able to release its
cooling air, the minimum distance over the unit must
be as shown in the table under Mechanical Dimension.
To protect the unit from overheating, it must be
ensured that the ambient temperature does not rise
above the max. temperature stated for the VLT
frequency converter and that the 24-hour average
temperature is not exceeded. The max. tempe-rature
and 24-hour average can be seen from the General
Technical Data in the Operating Instructions.
If the ambient temperature is in the range of
45 -55 C, derating of the VLT frequency
converter will become relevant, see Derating
for ambient temperature.
The service life of the VLT frequency converter will
be reduced if derating for ambient temperature
is not taken into account.

380-480 Volt Nema 1 (IP 20) and IP 54
Cooling
All units in the above-mentioned series require a
minimum space of 400 mm (15.75 in) above the
enclosure and must be installed on a plane floor. This
applies to both Nema 1 (IP 20) and IP 54 units.
Side-by-side
Nema 1 (IP 20) and IP 54
All Nema 1 (IP 20) and IP 54 units in the
above-mentioned series can be installed side by
side without any space between them, since these
units do not require cooling on the sides.

■Derating for high altitude
Below 1000 m altitude no derating is necessary for
VLT 5300-5500, VLT 6350-6550 or VLT 8350-8550.
Above 1000 m the ambient temperature (TAMB)or
max. output current (IVLT,MAX) must be derated in
accordance with the diagram below:
1. Derating of output current versus altitude
at TAMB = max. 45 C
2. Derating of max. TAMB versus altitude at
100% output current.
■Derating for ambient temperature
The ambient temperature (TAMB,MAX) is the maximum
temperature allowed. The average (TAMB,AVG)
measured over 24 hours must be at least 5ºC lower.
If VLT 5300-5500, VLT 6350-6550 or VLT 8350-8550
is operated at temperatures above 45 ºC, a derating
of the continuous output current is necessary.

VLT®5000/6000/8000 Series
■Electrical installation
The voltage on the frequency converter
is dangerous when the unit is
connected to mains.
Incorrect installation of the motor or VLT
frequency converter may lead to material damage
or serious injury or it may be fatal.
Consequently, the instructions in this manual
as well as national and local rules and safety
regulations must be complied with.
Touching the electrical parts may be fatal, even
after the mains supply has been disconnected.
Wait at least 15 minutes if using VLT 5300-5500,
VLT 6350-6550 or VLT 8350-8550.
NB!:
It is the user’s or certified electrician’s
responsibility to ensure correct earthing and
protection in accordance with applicable
national and local norms and standards.
All terminals for the control cables and power cables
are located behind the protective cover of the VLT
frequency converter. The protective cover can be
removed by means of a screwdriver.
Once the protective cover has been removed, the
actual EMC-correct installation can start.
■Pre-fuses
For VLT type 5300-5500, VLT type 6350-6550
and VLT 8350-8550, external pre-fuses must be
installed in the mains supply to the VLT frequency
converter or ordered with built-in pre-fuses and
a mains disconnect switch.
UL compliance
To comply with UL/cUL approvals, pre-fuses according to the table below must be used.

Non UL compliance
If UL/cUL is not to be complied with, we recommend
the above mentioned fuses or type gR.
Not following the recommendation may result
in unnecessary damage of the drive in case of
malfunction. Fuses must be designed for protection
in a circuit capable of supplying a maximum of
100000 Arms (symmetrical), 500 V maximum.
■Earthing
The following basic issues need to be considered
when installing a frequency converter, so as to
obtain electromagnetic compatibility (EMC).
•Safety earthing: Please note that the frequency
converter has a high leakage current and must
be earthed appropriately for safety reasons.
Apply local safety regulations.
•High-frequency earthing: Keep the earth wire
connections as short as possible.
Connect the different earth systems at the lowest
possible conductor impedance. The lowest possible
conductor impedance is obtained by keeping
the conductor as short as possible and by using
the greatest possible surface area.
The metal cabinets of the different devices are
mounted on the cabinet rear plate using the lowest
possible HF impedance. This avoids having different
HF voltages for the individual devices and avoids the
risk of radio interference currents running in connection
cables that may be used between the devices. The
radio interference will have been reduced.
In order to obtain a low HF impedance, use the
fastening bolts of the devices as HF connection to
the rear plate. It is necessary to remove insulating
paint or similar from the fastening points.

VLT®5000/6000/8000 Series
Electrical installation
■RFI switch
Mains supply isolated from earth:
If the VLT frequency converter is supplied from an
isolated mains source (IT mains), the RFI switch
can be turned off (OFF). In OFF position, the
internal RFI capacities (filter capacitors) between
the chassis and the intermediate circuit are cut off
to avoid damage to the intermediate circuit and
to reduce the earth capacity currents (according
to IEC 1800-3). See position of RFI switch by
Electrical installation, enclosures.
NB!:
The RFI switch is not to be operated with
mains connected to the unit. Check that
the mains supply has been disconnected
before operating the RFI switch.
NB!:
Open RFI switch is only allowed at factory
set switching frequencies.
NB!:
The RFI switch disconnects the capacitors
galvanically; however, transients higher
than approx. 1,000 V will be bypassed
by a spark gap.
Mains supply connected to earth:
The RFI switch must be in ON position in order for the
frequency converter to comply with the EMC-standard.
