Suitable provisions should be taken when routing any cables attached to the Hub to ensure that they
do not create a hazard.

Earthing

Both the Hub Unit and the Power Supply have M4 earth studs on the left side of their casing to allow
the UltraTEV Monitor to be bonded to an external ground system. Both the Hub Unit and Power
Supply cases must be bonded to earth when the UltraTEV Monitor™ is installed in a substation.

Connecting the Nodes

The UltraBus communication cables to the Nodes are wired in a daisy chain manner, i.e. each Node
has two connections, one for connection to the previous Node or Hub Unit (Server) and one for
connection to the next Node. The connections are made using CAT 7 Screened Twisted Pair (STP)
Ethernet cable. The cables supplied with the Monitor are colour coded to the colour blocks on the
Node label to simplify connection.

No specific Node connection order is required although a linear flow along the switchgear will make
the system easier to set up.
