■
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 corresponds
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 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 8000 AQUA 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.
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.
