Cut the cable 12 inches past the last module point (indention in
cable). Note: Cutting the cable between module points creates
a non-heating cold lead. See Figure 1.
Module Point
2. FOR CABLE WITH EXPOSED METAL BRAID (-C):
Push the braid back 12 inches on the cable. See Figure 2.
3. FOR ALL CABLES:
Feed the ends of the cables through the appropriate holes in the
base. Allow eight inches of cable to extend above the top of the
base. Slide cable grommet over the end of the cable and insert
it into the opening in the base. See Figure 3.
4. FOR ALL CABLES:
Secure the base to the pipe by threading the appropriate sized
pipestrap through the slot in the mounting plate. Tighten the
pipestrap until the base is securely attached to the pipe. Slide
cable grommet over the end of the cable and insert it into the
opening in the base. See Figure 4.

5. FOR OVERCOATED CABLES (-CR or -CT):
Score the outer insulation 1-1/2 inches from the end of the cable.
Remove the jacket to expose the metal braid. See Figure 5.
WARNING: Do not damage the braid or the base cable insu-
lation.

6. FOR ALL CABLES:
Punch out the knockouts on the bottom of the box which cor-
respond to the openings in the base through which the heating
cable passes. If you should make a mistake, blank grommets
can be ordered to re-establish the water tight seal. See Figure 6.
7. FOR ALL CABLES:
Feed the cables through the corresponding holes in the box.
Secure box to base using all four large (8-32) screws. See
Figure 7.

8. FOR OVERCOATED CABLES:
Starting from the end of the cable, unravel 1-1/2 inches of the
braid. Twist the strands together to form a pigtail. See Figure 8.
9. FOR SELF-REGULATING CABLES:
Using standard electrical cutters, cut a 3/4 inch long notch out
of the cable between the conductor wires. Bare a 3/8 inch
length of each conductor by stripping off the outside insulation
and the inner black core material. See Figure 9.
Figure 8
10. FOR CONSTANT WATTAGE CABLES:
Score the outer jacket 3/4 inch from the end of the cable and
remove the jacket. Cut off the exposed nichrome wire, pushing
any remainder back under the jacket. Constant Wattage cables
have an inner layer of insulation which is also to be removed as
described above. Separate the buss wires and strip off the last
3/8 inch of insulation from both buss wires. See Figure 10.
11. FOR OVERCOATED CABLES:
Slide the insulating tube over the end of the cable. Insert the
end of the braid pigtail into the opening in the terminal block
which will be nearest the center of the box. Tighten the screw
firmly to hold the braid in place. See Figure 11.
