ST950S Plus+ Installation and Commissioning Manual
Important:
Prior to installation please confirm that the junction design engineer has completed the first part
and the second half as verification that the electrical design, including junction cabling, is as
required in Junction Cabling Design Guide.
If the installers have deviated from the Plus+ Layout Design (see next point), the installers
must sign off the second part to confirm the installation continues to meet regulations.
Additionally, ensure that the Site Layout Drawing Number and Revision are recorded on the
certificate.
Important:
If there are significant differences in the actual ducting and that in the drawing, e.g. a duct had
to be placed in a different position, then if any cable run is marked as Amber on the drawing
raise the issue with the designer before installing any cables.
If the cable run is marked as Green on the drawing, then the Commissioning Engineer should
review the percentage loading on the drawing and make a best judgement if the installation
can continue without re-assessment.
If there is any doubt, please contact Yunex Traffic Technical Support.
6.6.1. Cable Installation to Controller
Wiring runs should be made as neat as possible. The Plus
+
Design Tool allows for several meters
of spare cable which can be used for future possible changes and/or additions. If cable idents are
required, these should be fitted to cores before termination.
All cables into the controller should be fed into the outer case, through the CET glands, via CET bars,
when using the Compact Controller Stool or through the Glands and CET bars and CET glands when
using the NAL base. Care must be taken not to obstruct the Electricity Supply Company cut out with
any cabling.
6.6.2. Terminate the cable armouring (Plus
+
Stool)
The components on the Sealed Base Kit are described in
1. Loosen nuts on the top clamps.
2. Remove top clamp.
3. Remove base plug from the base seal block.
4. Remove the stool door.
5. Feed cable up into cabinet through the base plate and compression seal.
6. If cable is loose in the compression seal, then select a suitable shim for the cable diameter.
