Use in maritime and offshore applications

The UC20 products described in this manual comply with
the requirements of the classification society DNV. These
products are approved for the usage in maritime and off-
shore applications. The certificates including the particu-
lar location classes are available for download from the
Weidmüller website.
Please regard the following in the case of maritime or offsho-
reapplications:
– The permissible temperature range can be found in the
respective certificate.
– For products with maritime approval, a supply voltage
range of 24 V DC +30 %/–25 % applies.
– The lower limit for the supply voltage is 18.0 V. For the
UC20 products to function properly, the voltage drop on
the current paths must not exceed 0.75 V.
– If you want to operate the controller with a microSD card,
you must use the SD-CARD-8GB (Order No.
2684400000) to ensure compliance with maritime EMC
requirements.
For information on the maximum number of u-remote mod-
ules that can be connected in series without further power
supply, please refer to the u-remote manual.
Installation with maritime and offshore applications
For vibrations up to a maximum of 0.7 g:
The u-control station can be mounted on a 35x7.5 mm or
a 37x15 mm DIN rail. Up to 64 UR20 modules can be in-
stalled in one station.
For vibrations above 0.7 g up to a maximum of 4 g:
The u-control station must be mounted on a 35x7.5 mm DIN
rail with mounting plate. Up to 50 UR20 modules can be in-
stalled in one station.

"PUSH IN" system cabling

Controllers are equipped with the "PUSH IN" connector system.
Single-strand and fine-strand lines with wire-end ferrules can
be inserted without the need for a tool. Copper wires with a
cross-section measuring between 0.14 mm
can 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. For crimping, we recom-
mend crimp shape A and the following tools:
– Crimping tool for wire-end ferrules from 0.25 mm² to
1.5 mm² (AWG 24 to 16) 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 26 to 18) with a trapezoidal crimp, type:
PZ 1.5 ZERT (Order No. 9017310000)
