If necessary the Hub Unit and Power Supply may be installed next to each other horizontally, but
must be installed the correct way up to allow sufficient cooling. To ensure the interconnector cable
will reach, do not space the units more than 50mm (2 inches) apart horizontally.
Contact EA Technology Product Support if any other form of installation is required:

Figure 21: Diagram showing main Power Supply and Hub Unit connections, and minimum clearances for installation
horizontally.
Keyhole slots are provided at the edges of each enclosure and these should be used to attach the
units to the wall or to a suitable mounting plate. Ensure that the wall is suitably strong enough to
support the Hub Unit and Power Supply. Use the screws and Rawlplugs supplied with the Monitor
(Red Rawlplugs for 6mm drill and 5mm screws), or alternative comparable wall fixings.
A cable must also be connected from the Hub Unit to the first Node in the chain. Additional cables
may be needed for LAN/WAN or SCADA connections. Suitable provisions should be taken when
routing these cables to ensure that they do not create a hazard.
7.2 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.
