■ 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.
