VLT® 8000 AQUA

■ Line connection

Line must be connected to terminals 91, 92, 93.

Nos. 91, 92, 93 Line voltage 3 x 200-240 V

L1, L2, L3 Line voltage 3 x 380-480 V

Line voltage 3 x 525-600 V

NOTE

Check that the line voltage corr

esponds

to the line voltage of the AFD, which can

be seen from the nameplate.

See Technical data for correct sizing of cable

cross-sections.

NOTE

It is the responsability of the user or installer

to ensure that proper grounding, branch

circuit, and motor overload protection is

in accordance with national and local electrical

and safety regulations and codes.

■ Motor connection

The motor must

be connected to terminals 96,

97, 98. Ground to terminal 94/95/99.

Nos.

96. 97. 98

U, V, W

Motor voltage 0-100 % of mains voltage

No. 94/95/99 Ground conne

ction

See Technical data for correct sizing of cable

cross-sections.

All types of three-phase asynchronous standard motors

canbeusedwithaVLT8000AQUAunit.

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.

NOTE

In older motors without phase coil insulation, a

LC filter should be fitted to the AFD output.

■ Direction of IEC motor rotation

The factory setting is for clockwise rotationwith the VLT

frequency transformer output connected as follows.

Terminal 96 connected to U-phase

Terminal 97 connected to V-phase

Terminal 98 connected to W-phase

The direction of rotation can be changed by switching

two phases in the motor cable.

■ Parallel coupling of motors

VLT 8000 AQUA is able to control several motors

connected in parallel. If the motors are to have different

rpm values, the motors must have different rated

rpm values. Motor rpm is changed simultaneously,

which means that the ratio between the rated rpm

values is maintained across the range.
