4. Use cable ties to secure the cables to the edge of
the mounting ring, as shown in Figure 5. Keep in
mind the side of the sewer that will allow for the
cables to stay clear of the flow.
Figure 5: Secure the Cables
5. Use cable ties to tie the lengths of cable together,
using one tie per foot of cable.
6. Reinstall the mounting ring and route the cables
so they are clear of the flowing water.
Do not
loop the GEC cable; cut it to length.
If there is
excess probe cable such that it is looped to keep
it out of the way, route the GEC cable separately.
7. Disconnect the modem line from the 2103. Con-
nect the secondary protector to the 2103, as
shown in Figure 6. Connect the modem cable to
the end of the secondary protector.

8. Reinstall the 2103 and 2150. Route the secondary
protector conductor wire and the GEC conduc-
tor cable through the manhole casing to the
grounding point.
CAUTION
Do not loop the wires!
This can form an inductor
and permanently damage your equipment.
The
cables can be loose with easy bends around corners for
convenient routing, but should be cut as short as
practical.
9. Cut the conductors to the length necessary to
connect to the ground point, leaving enough
length to allow for the equipment to be serviced
outside the manhole. Strip the conductors and
connect them to the ground point, as shown in
Figure 7.
