6.3 Power and Grounding
6.3.1 Power Connector
Watson SHDSL router is designed to be powered from an AC mains power sup-
ply voltage of 110 VAC to 240 VAC at a frequency of 50 Hz to 60 Hz. The circuit
fuse rating must not exceed 10 Amps. The socket outlet shall be installed near
the equipment and shall be easily accessible.
A power cable with an IEC320-C7 style connector can be used for this purpose.

6.3.2 Ground Connector
Watson SHDSL router is fitted with a ground connector (Functional Earth). The
functional earth does not serve the purpose of providing protection against elec-
trical shock, but instead enhances surge suppression on the SHDSL lines for in-
stallations where suitable bonding facilities exist.
Do not connect this terminal to the protective earth (PE) at the socket outlet
where the CPE is plugged in. This terminal may be left unconnected where no
suitable bonding facilities exist.
Figure 6-4: Ground Connector
The connector type is Faston 4.8 x 0.5 mm connector (DIN 46244) The hole in
the rear panel is dimensioned for non-insulated Faston ferrules (DIN 46245).
