Wiring

Explosion risk!
▶ Before assembly, make sure that there is
not a potentially explosive atmosphere!
▶ For applications in potentially explosive
atmospheres, observe the installation and
construction requirements of EN 60079-
15 and/or country-specific regulations.
Dangerous contact voltage!
▶ Carry out assembly and wiring work on
the u-control station only when the power
supply is disconnected.
▶ Make sure that the place of installation
(switch cabinet etc.) has been discon-
nected from the power supply!
Safety functions can be impaired!
When safe I/O modules or safe power-feed
modules are installed in the u-control station,
please observe the following points:
▶ Please use wire-end ferrules in combina-
tion with flexible/multi-conductor cables to
avoid cross-circuits.
▶ Ensure that for safety inputs in the config-
uration without test pulses the cabling
prevents external short circuits (see
DIN EN ISO 13849-2 Table D.4).
Once the u-control station has been mechanically installed,
the wiring can be carried out in accordance with the wiring
plan.

WARNING

WARNING
Wiring of modules with connectors PG 1.5 mm
Only copper wires with a cross section between 0.14 mm²
and 1.5 mm² (AWG 16 – 26) may be connected.
We recommend using the following wire-end ferrules:
Cross-section
AWG
0.14 mm² 26
0.25 mm² 24
0.34 mm² 22
0.50 mm² 20
0.75 mm² 18
1.00 mm² 17
1.50 mm² 16
Wire-end ferrules for the wiring
The external dimensions of the crimped wire-end ferrules
must conform with IEC-60947-1. We recommend the follow-
ing tools for crimping:
– Crimping tool for wire-end ferrules from 0.25 mm² to
1.5 mm² (AWG 16 – 24) with a trapezoidal indentation
crimp, type: PZ 6/5 ZERT (Order No. 9017900000)
– Crimping tool for wire-end ferrules from 0.14 mm² to
0.75 mm² (AWG 18 – 26) with a trapezoidal crimp, type:
PZ 1.5 ZERT (Order No. 9017310000)
u-remote modules (except HD modules) and controllers
are equipped with the "PUSH IN" connector system. Sin-
gle-strand and fine-strand lines with wire-end ferrules can be
inserted without the need for a tool.
▶ Each cable must be the optimal length so that the bend-
ing radii observe the manufacturer's specifications.
▶ Strip the insulation from the lines to a length of approx.
10 mm ± 1 mm, even if you are using wire-end ferrules. If
you use wire-end ferrules with plastic collars, strip the
wires to 12 mm ± 1 mm.
▶ Connect all lines according to wiring diagram.
For the usage and handling of the "PUSH-IN" system, see
section 4.7.
