With size 8 and mains operation AC 3x 525 V or AC 3x690 3x525 V the terminal X13 must be con-
nected additionally. Follow the connection instructions for size 8.

Mains connection

A
The mains supply cable may be as long as required. To be installed separate
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
shielded, 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 (in example terminal X210A, X210B) are separated
by protective separation and protection from the main voltage circuit (in ex-
ample U, V, W).
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 the 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 brake 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 allows the operation of current intensive signals.
