WARNING
Explosion risk!
During assembly work, sparks can form and
surfaces may become excessively hot.
▶ 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-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!
6.1 Preparations for assembly
The controller is designed for installation in switch cabinets,
terminals or switch boxes in decentralised systems. The con-
troller and I/O modules conform to protection class IP20.
Environmental conditions
Make sure that the permitted environmental conditions for
installation and operation are observed (see the general tech-
nical data in section 3.2).
DIN rail
The controller is designed to be installed on a DIN rail (35 ×
7.5 mm or 35 x 15 mm) made from steel or galvanised steel
according to EN 60715. The DIN rail must be mounted prior
to the installation of the controller.
The DIN rail must be attached to the surface at least every
20 cm to protect it from vibration and impact. If it is installed
on earthed mounting plates, it does not have to be separate-
ly earthed.
Stripping lengths
The required stripping length for every Weidmüller product
is specified in mm. These lengths, e.g. 6 mm ± 0.5 mm,
≥ 10 mm ±1 mm, must be observed. This also applies to
the use of wire-end ferrules. The external dimensions of the
crimped wire-end ferrules must conform with IEC-60947-1.
For detailed information see section 6.3.
