Tightening-Up Torque And Screw Sizes; Mains Connection; Motor Connection - Danfoss VLT 7000 Series Manual

Tightening-up torque and screw sizes

The table shows the torque required when
fitting terminals to the frequency converter. For
VLT 7002-7072, 380-460 V the cables must
be fastened with screws.
These figures apply to the following terminals:
Mains terminals (Nos.)
Motor terminals (Nos.)
Earth terminal (Nos.)
VLT type Tightening-up
3 x 380-460 V torque
VLT 7002-7011 0.5-0.6 Nm
VLT 7016-7027 1.8 Nm (IP 20)
VLT 7032-7052 3.0 Nm (IP 20)

1. Loadsharing terminals 14 Nm/M6, 5 mm Allen key
3. Allen screws (hexagon)
4. Loadsharing terminals 9.5 Nm/M8 (bolt)

Mains connection

Mains must be connected to terminals
91, 92, 93 Mains voltage 3 x 380-460 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.
