In addition to contactor control, two feedback signals can be sent to the
SmartWire-DT system on each SmartWire-DT module for DILM.
The "Enable" ⑧ auxiliary contact is factory fitted with a link. If electrical locks
are envisaged in the application, the bridge can be removed and a potential-
free contact can be connected.
The auxiliary switches integrated into the contactor can be used, for exam-
ple, as safety locking devices.
Two feedback inputs to the programmable logic controller are available at the
three-pole terminal of connection ⑦ for the potential-free contacts. If
required, potential-free auxiliary contact contacts of the protective motor
switch PKZ can be connected to these two feedback inputs (e.g. NHI-E-…-
PKZ0 standard auxiliary contacts, AGM2-…-PKZ0 differential trip-indicating
auxiliary contact).
The connection terminals on the SmartWire-DT module for DILM are suitable
for cables AWG24 to AWG16 and flexible cables with a cross-section of 0.25
mm
2
to 1.5 mm

.
When using ferrules it has to be ensured that the ferrule length is at least 8
mm.
A manual or electrical ON or OFF command for the contactor can take place
in addition with the aid of the 1-0-A switch ⑨ in the device version DIL-SWD-
32-002.
The switch positions are as follows:
• 1 - Contactor ON
• 0 - Contactor OFF
• A - Switching command via SmartWire-DT
ATTENTION
The SmartWire-DT module for DILM drives the contactor so that
terminals A1-A2 must no longer be wired.

DANGER
The "Enable" auxiliary contact must not be used for safety-
related controller parts (￫ Section 3.3.3, „Safety-related appli-
cations“, page 73).
ATTENTION
The connection cables to the potential-free auxiliary contacts at
connection X0-X1-X2 ⑦ for the potential-free contacts and at
connection X3-X4 ⑧ for the "Enable" auxiliary contact may have
a maximum length of 2.8 m.
