■ Tightening-up torque and screw sizes
The table shows the torque required when fitting
terminals to the VLT frequency converter. For VLT
6002-6032, 200 -240 V, VLT 6002-6062, 380-460 V
the cables must be fastened with screws. For VLT
6042-6062, 200-240 V and for VLT 6075-6275 the
cables must be fastened with bolts.
These figures apply to the following terminals:
Mains terminals
Motor terminals

■ Mains connection
Mains must be connected to terminals 91, 92, 93.
Mains voltage 3 x 200-240 V
Mains voltage 3 x 380-460 V
NB!
Check that the mains voltage fits the mains
voltage of the VLT frequency converter, which
can be seen from the nameplate.
See Technical data for correct sizing of cable cross-
sections.

■ Pre-fuses
For VLT type 6002-6275, external pre-fuses must be
installed in the mains supply to the frequency
converter. For UL/cUL applications with a mains
voltage of 200-240 V, pre-fuses of type Bussmann
KTN-R (200-240 V) or similar must be used. For UL/
cUL applications with a mains voltage of 380-460 V,
pre-fuses of type Bussmann KTS-R (380-460 V) or
similar must be used.
For VLT type 6060-6275 HVAC, 380/460 V and VLT
6032-6052, 200-240 V, pre-fuses are included in the
frequency converter mains connection; however,
external pre-fuses must also be fitted.
See Technical data for correct sizing of pre-fuses.

■ Motor connection
The motor must be connected to terminals 96, 97,
98. Earth to terminal 99.
Motor voltage 0-100% of
netspænding. mains voltage.
Earth connection.
See Technical data for correct sizing of cable cross-
sections.
All types of three-phase asynchronous standard
motors can be used with a VLT 6000 HVAC unit.
Small-size motors are normally star-connected.
(220/380 V, ∆/Y). Large-size motors are delta-
connected (380/660 V, ∆/Y).
The correct connection and voltage can be read from
the motor nameplate.
NB!
In older motors without phase coil insulation, a
LC filter should be fitted to the VLT frequency
converter output. See the Design Guide or contact
Danfoss.
