Cabling (unused wires)
Any unused wires in the connecting cables should be connected to ground
preferably at the user equipment end.
Cabling protection
The Cable should be secured:
With cable clamps or equivalent at regular intervals such that the hub
box cable gland does not support the cable weight.
Away from the mounting bolts to prevent chaffing of the cable.
NOTE.
Install appropriate strain relief support to the cable. If possible, pass the
cable through the mounting pole.
Earthing
To ensure correct operation and for maximum protection from lightning, a separate
lightning rod system is recommended to protect the system.
You can also earth the MetPak RG through its mountings or by connecting a
grounding cable (minimum of 6mm² copper wire) to a spare MetPak RG metalwork
bolt hole. Clean off any paint that might prevent a good connection.
When you connect the communications cable ensure that the screen has a
connection to the hub box case.
Routing Cables through the Hub Box Glands
NOTE
: The MetPak RG Hub Box cable glands contain spring loaded metal leaves
that are designed to make a ground contact with cables that have an overall braid
screen. Care is therefore required when inserting and removing cables through the
glands to prevent damage to the metal leaves.
