■ Enclosure
VLT 6000 HVAC is available with the following
enclosures:
- IP 00: 30 to 45 kW / 200-240 V
- IP 00: 55 to 200 kW / 380-460 V
- Bookstyle IP 20: 1.1 to 3.0 kW / 200-240 V
- Bookstyle IP 20: 1.1 to 7.5 kW / 380-460 V
- IP 20: 1.1 to 45 kW / 200-240 V
- IP 20: 1.1 to 200 kW / 380-460 V
- IP 54: 1.1 to 45 kW / 200-240 V
- IP 54: 1.1 to 200 kW / 380-460 V
IP 00: This enclosure is only available for the larger
power sizes of the VLT 6000 HVAC series. It is
recommended for installation in standard cabinets.
IP 20 Bookstyle: This enclosure is designed for
cabinet installation. It takes up a minimum of space
and can be fitted side-by-side without installation of
extra cooling equipment.
IP 20: This enclosure is used as standard enclosure
for VLT 6000 HVAC. It is ideal for cabinet installation
in areas where a high degree of protection is
required. This enclose also permits side-by-side
installation.
IP 54: This enclosure can be fitted direct to the wall.
Cabinets are not required. IP 54 units can also be
installed side-by-side.

■ RFI filter
As standard, the VLT 6000 HVAC has an integral
RFI filter up to and including 7.5 kW (3 kW 200 V).
These RFI filters comply with EMC standards EN
55011-1A, provided max. 150 m screened/
armoured cable is used, and with EN 55011-1B,
provided 50 m screened/armoured cable is used
(Bookstyle max. 20 m screened/armoured).

■ Control unit (LCP)
The VLT 6000 HVAC is available with or without
control unit (LCP); however, IP 54 units always
come with the control unit.
This control unit makes up a complete interface for
control and programming of the VLT 6000 HVAC.
The control panel is detachable and may - as an
alternative - be mounted up to 3 metres away from
the VLT frequency converter, i.e. in a cabinet, by
means of a fitting kit delivered with the unit.
Data information is given in a 4-line alpha-numerical
display, which under normal operation is able to
continuously show four operating data items and
three operating modes. During programming, all the
information required for quickly and efficiently setting
up VLT frequency converter parameters will be
shown.
As a supplement to the display, there are three
indicator lamps for voltage (ON), warning
(WARNING) and alarm (ALARM).
All VLT frequency converter parameter Setups can
be changed directly via the control panel.
The following options are available:
- Control panel LCP (only for IP 20 units).
- LCP remote-mounting kit for remote control of
IP 00 and IP 20 units.
- LCP remote-mounting kit for remote control of
IP 54.
- 3 metre cable for LCP.
Select a RFI filter for dampening of interference in
accordance with EN 55011-1A and EN 55011-1B.

■ Harmonic filter
The harmonic currents do not directly affect the
electricity consumption, but they do increase the
heat losses in the installation (transformers, cables).
That is why in systems with a rather high
percentage of rectifier load it is important to keep
the harmonic currents at a low level in order to
avoid transformer overloads and high cable
temperatures.
As standard, the VLT 6000 HVAC has coils in the
intermediate circuit in order to ensure low
harmonic currents. This typically reduces the
input current I
RMS
by 40 %.
