Without ground rod:
Crimp an appropriate spade lug to the ground wire from each terminal block, and screw the
lug to a screw hole on the rack. Remove the paint and sand the area around the screw hole to
ensure proper conductivity. Coat the connection with an electrically conductive antioxidant
compound, for example, Kopr-Shield spray.

Power

Warning:
Power source protective fusing must be provided as part of the installation.
Caution:
procedure. Before connecting the power cables to the TimeSource 3100, ensure the fuses are
removed from the fuse panel that supplies power to the power cables.
Note:
TimeSource 3100.
The –48 volt dc battery enters through the four-position power terminal blocks labeled TB1
and TB2. Figure 13 shows the location of the terminal blocks, and Figure 14 shows the
terminal block connections.
Ensure the power wires are long enough to reach from the shelf connector panel to the office
battery source connection. Use two 1.47mm (16 AWG) stranded wires for the power
connection, one with red insulation (BATT), and the other with black insulation (RTN).
Connect the power wires with red insulation to the BATT wire receptacles on TB1 and TB2.
Connect the power wires with black insulation to the RTN wire receptacles on TB1 and
TB2.
Note:
separate office battery supplies are not available, connect a single office battery to both inputs
(TB1 and TB2) to avoid a standing battery-failure alarm.

GPS Antenna

Connect the coaxial cable from the lightning suppressor to the TNC connector labeled GPS
ANT. See Figure 13 for the connector location.

10 MHz Output

Connect an RG-58 coaxial cable from the connector labeled 10 MHz to the equipment that
will use the 10 MHz output signal. See Figure 13 for the connector location.
