sealed base kit provides 4 cable entries for mains & data plus an additional 12 cable
entries. See Figure 60. If additional cable entries are required then the Plus
+
cable seal expansion
kits must be used (667/1/53065/008), each kit provides 8 additional cable entry glands.
6.6.5 Terminate cables at the PTB (Pole Top Board)
Termination of the Feeder Cable at the Pole Top Board is recommended at this stage. This allows
for the cable testing to proceed.
Reference section 4.1 for detailed information.
6.6.6 Cable Testing
If the site contains a ring cable arrangement the following test should be considered after the site
has been commissioned and while the signals are bagged;
Identify a safe position where the ring can be broken.
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.
