Step 9.
Install shear bolt connector
ote:
N
Refer to the 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.
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 BOL-T T-body with mating parts
Step 11.
Install DT625 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.
•
Go to Step 12, page 12 to complete T-body termination.
