3.4.3 GROUNDING CONNECTION
Ground Connection
To ensure safe operation of the product, a ground (earth) connection is required. For single phase AC
power source, the product must be grounded by connecting the “earth wire” of the power cord to the ground
terminal of the AC supply. For operating this product with DC power system (such as rectifiers), the product
should not be connected to power systems that switch open the return lead because the return lead could
function as the ground (earth) connection for the equipment.
Protective Ground Connection
The enclosure must be grounded securely by connecting a copper wire (CSA 16mm

Protective Ground Connection
The enclosure must be grounded securely by connecting a copper wire (CSA 16mm
2
) to the grounding
terminal on the equipment/rack, and the other end to a protective ground (i.e. building earth point). An
internationally acceptable colour code of the ground connection wire is green/yellow.
Such a ground connection implements the “Protective Ground Connection”, and must be connected to the
equipment at the designated ground point. In general, do not connect the supply before establishing an
adequate ground (earth) connection.
Construct the ground wire, and use appropriate crimp connectors where necessary. Locate and connect
the equipment grounding terminal to a protective ground (i.e. building earth point).

3.4.4 RF CABLE CONNECTION
Single band PS BDA RF cables connection is as follows:
PS BDA MT port Connects to the feeder cable from service antenna.
PS BDA DT port Connects to the feeder cable from donor antenna.
3.4.5 ETHERNET CONNECTION
Connect Ethernet with
‘LAN’ port in the panel, Ethernet type only.
