4. If the field pulse cable is smaller than a 0.2-inch diameter, install the rubber tube supplied with the TCI
onto the cable so the strain relief will clamp onto the tube after it is reinstalled.
5. Connect the individual external pulse cable conductors to the unterminated wires following Configuration
for two ERT modules connected to one TCI. Insert one unterminated wire into an opening of a gel-
connector (six gel-connectors were included with the TCI). Insert the appropriate field cable wire into the
other gel-connector opening.

6. Verify both wires are fully inserted into the gel-connector prior to crimping.
Important Use a crimping tool compatible with gel-connectors. Do not use a standard pliers for crimping
gel-connects. The crimping tool provides an even pressured crimp to make a secure connection. Apply
pressure for three seconds until the gel cap is fully crimped (collapsed) to allow time for the low viscosity
silicone-based gel to flow. If the silicone gel flows out of the crimped connector, avoid touching the gel.
Gel flowing from the connector provides environmental protection for the connection.
