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-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!
7.1 Preparations for assembly
The u-remote station is designed for installation in switch
cabinets, terminals or switch boxes in decentralised systems.
The eldbus coupler 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 Sections 3.2 and 3.4).
DIN rail
The u-remote station 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 u-remote station.
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 sepa-
rately earthed.
Stripping lengths
The required stripping length for every Weidmüller product
is specied 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 7.5.
Unpacking the delivery
All of the elements that make up the u-remote station are
packaged individually for delivery.
▶ Please check the delivery for completeness and transport
damage.
▶ Please report any transport damage immediately to the
respective transport company.
ATTENTION
The product can be destroyed by elec-
trostatic discharge!
The components in the u-remote series can
be destroyed by electrostatic discharge.
▶ Please make sure that personnel and work
equipment are adequately earthed!
▶ Unpack all parts and sort the modules into the installation
sequence as per the instructions.
▶ Dispose of all packaging in accordance with the local dis-
posal guidelines. The cardboard packaging from the mod-
ules and fieldbus couplers can be sent for paper recy-
cling.
