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 380-460 V
Line voltage 3 x 525-600 V
NOTE
Check that the line voltage corresponds to
the line voltage of the VLT AFD, which can
be seen from the nameplate.
See
Technical data
for correct sizing of cable
cross-sections.
The voltage of the adjustable frequency drive
is dangerous when the unit is connected
to the AC line. Incorrect installation of the
motor or the VLT adjustable frequency drive may lead
to material damage, serious injury or death. Follow the
instructions of this manual and comply to the National
Electrical Code (NEC) and local codes and safety
guidelines. DO NOT touch the electrical components
of the VLT adjustable frequency drive for at least 30
minutes after the AC line has been disconnected.
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 the NEC and local safety codes.
NOTE
If UL/cUL is to be complied with, use copper wire
with a temperature rating no less than 75° C.
