Tightening-up torque and screw sizes

The table shows the torque required when fitting
terminals to the frequency converter. For VLT
6002-6032, 200-240 V, VLT 6002-6122, 380-460 and
VLT 6002-6072 525-600 V the cables must be fastened
with screws. For VLT 6042-6062, 200-240 V and
for VLT 6152-6550, 380-460 V and VLT 6102-6652,
525-600 V the cables must be fastened with bolts.
These figures apply to the following terminals:
Mains terminals (Nos.)
Motor terminals (Nos.)

Mains connection

Mains must be connected to terminals 91, 92, 93.
Mains voltage 3 x 200-240 V
91, 92, 93 Mains voltage 3 x 380-460 V
L1, L2, L3 Mains voltage 3 x 525-600 V
NB!:
Check that the mains voltage fits the mains
voltage of the frequency converter, which
can be seen from the nameplate.
See Technical data for correct sizing of cable
cross-sections.

Motor connection

The motor must be connected to terminals 96,
97, 98. Earth to terminal 94/95/99.

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,
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 frequency converter output. See the
Design Guide or contact Danfoss.
