Step 10.
Check di men sions
•
Check length from end of com pres sion con nec tor to top
of cable adapter.
Length should be no longer than "E" dimension. (Re fer to
Fig ure 12 and Table 2.)
Install BT-TAP T-body with mating parts
Step 11.
Install DT635 T-body
•
Clean and lubricate outside of cable adapter with lubricant
supplied.
•
Clean and lubricate inside of T-body with lubricant
supplied.
ote:N If test point T-body is used, insure test point is
opposite front plate side of T-body.
•
Without moving the cable adapter, slide T-body onto cable
adapter until compression connector eye is centered in
600 A interfaces. (Refer to Figure 13.)
ote:N The end of the cable adapter must line up with
the top edge of the tape marker after T-body
assembly. Refer to Figure 10.
•
Remove tape marker from cable.
Step 9.
Install compression connector
ote:N Refer to separate installation instructions
supplied with the shear bolt connector.
•
Install centering ring.
• Refer to Figure 11 and Table 1 to determine what size
conductors require a centering ring and the correct
color to use.
•
Wire brush conductor (aluminum only).
•
Immediately insert the conductor completely into the
barrel of the lug and rotate connector to distribute
inhibitor.
•
Align flats of connector and apparatus bushing for
minimum conductor strain.
ote:N Connector must be fully seated on cable
conductor.
•
With an Allen hex key as specified in Table 2 screw in bolt
No. 1 until it breaks off smoothly. Proceed with bolt No.
2 in a similar way. If the lug has more than two (2) bolts,
continue with bolt No. 3 and bolt No. 4, (not shown in
Figure 11). See Figure 11 for tightening sequences.
•
Once all the bolts have broken off, smooth any rough
edges with a file and install the covering caps. Carefully
clean off any filings.
•
Wipe excess inhibitor from connector and adapter
surfaces.
