The figure schematically shows the connection between drive and motor;
it points out the connection between the motor housing and the drive
electrical panel ground bus bar made by drive-motor connecting cables
(screen and PE conductors). Drive-motor connections with two screened cables
NOTE
Very long motor cables, due to the leakage current to ground and the high
switching frequency, can cause the intervention of the ground fault relief
device. Replace the device with a less sensitive one or power the drive with
a dedicated transformer.
5.9.4 MOTOR CABLES - 5.9.4.1 - 5.9.4.2
Connections on drive side:
a. The PE conductors and the screens must
be connected to the ground bus bar of the
drive electrical panel;
b. If for reasons of current capacity it is necessary
to use more cables in parallel, it is necessary
to connect the three conductors of each
three-pole cable to the three phases U, V, W.
Motor connection:
c. The PE conductors and the screens must be
connected to the motor housing; for this
purpose the motor terminal box must be
provided with an appropriate fixing plate;
d. If for reasons of current capacity it is
necessary to use more cables in parallel, it is
necessary to connect the three conductors
of each three-pole cable to the three phases
U, V, W.
