ST950S Plus+ Installation and Commissioning Manual
A single break in the 48V power cabling will not result in the failure of any Nodes. However, if any
nodes do fail it suggests that there is a break in the power part of the ring.
This test is not required for the data pair as this is a monitored function of the controller.
The electrical testing of the controller and cables are based on a PELV system, as defined in the IET
Wiring Regulations (BS 7671). There may be specific or additional customer requirements for testing
the cabling.
Site cabling must be tested against the requirements of the Installation and Commissioning Handbook
– Installation Testing (General) (667/HE/20664/000).
Important:
Do NOT test any site cabling without reference to this document (667/HE/20664/000).
Additionally, with or without testing the Traffic Signal Installation Completion Certificate (667/
HE/20664/001) needs to be completed as part of the completion of site commissioning (see
Section
Installing the On Street Equipment
Additionally, the cable testing should not be carried out once the Node are connected to the
system.
6.6.7. Fitting the Cabinet to the Stool
Clean the top surface of the stool and the lower surface of the cabinet that will be in contact when the
cabinet is fitted. Apply a bead of silicone sealant around the edge of the stool.
Apply silicone sealant (ref. part no. 996/4/22026/100) to the top surface of the stool (enough to ensure
that a good seal between the stool and the cabinet will be made).
The cabinet is installed by lowering it onto the stool and fitting the retaining bolts.
When fitting the cabinet onto the stool, make sure that all the cables are in their correct position with
regard to the SEB. Once the cabinet has been secured, moving of the cables could cause damage.
Important:
If the Plus+ Controller Cabinet is being mounted on a Standard Controller Stool, then there will
also need to be a process of backfill and base sealant application.
Detailed information can be found in the Stool Installation Document (667/CC/53060/000).
6.7. Re-fit the Controller Electronics (if applicable)
Re-fit the electronics into the controller case, checking that:
•
All cards are seated correctly in their sockets
•
All plugs and sockets are securely mated
•
All fixings are tight – especially those securing cards to side or back panels of the cabinet.
