Mains Connection - BONFIGLIOLI Vectron ACTIVE CUBE Série Guide Rapide

GB
As from size 8, with AC 3x525 V or AC 3x690 V mains operation, terminal X13 must be connected
additionally. Note the connection information for size 8.

Mains connection

A
The mains supply cable may be as long as required. To be separated from
control, data and motor cable.
DC-link connection
B
The frequency inverter is to be connected to the same mains potential or a
common direct voltage source. Cables with a length >300 mm must be shiel-
ded, the cable shield must be connected to the mounting plate on both sides.
Use twisted cables where possible.
Control connection
C
Control and signal cables must be kept physically separate from the power
cables. Analog signal lines are to be connected to the shield potential on one
side. Install sensor cables separate from motor cables.
The low voltage circuits (e.g. terminal X210A, X210B) are isolated from the
main circuit (e.g. U, V, W) by way of safety isolation and safety impedance.
Motor and brake resistor
D
The shield of the motor cable is to be connected to ground potential properly
on both sides. On the motor side use a metal compression gland. On the
frequency inverter side an appropriate shield clamp is to be used. The signal
cable used for monitoring the motor temperature must be kept separate from
the motor cable. Connect the shield of this line on both sides. If a braking
resistor is used, the connection cable must also be shielded, and the shield is
to be connected to earth potential on both sides.
Relay
The relay enables using high-energy signals.
