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

) to the grounding terminal
on the equipment/rack, and the other end to a protective ground (i.e. building earth point). An internationally
acceptable color 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 antennas.
PS BDA MT port Connects to the feeder cable from service antennas.
PS BDA DT port Connects to the feeder cable from donor antennas.
3.4.5 ETHERNET CONNECTION
Connect Ethernet with
‘LAN’ port in the panel, Ethernet type only.
