WARNING
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.
WARNING
Dangerous contact voltage!
▶ Carry out assembly and wiring work on
the u-remote 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!
WARNING
Safety functions can be impaired!
When safe I/O modules or safe power-feed
modules are installed in the u-remote 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-remote station has been mechanically installed,
the wiring can be carried out in accordance with the wiring
plan.

Wires with a cross section between 0.14mm² and 1.5mm²
(AWG 16 – 26) can be connected.
We recommend using the following wire-end ferrules:

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 bus couplers
are equipped with the “PUSH IN” connector system. Single-
strand and ne-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 11.5.
