This section covers various maintenance procedures for the HRE-458.
Splicing
Splicing consists of connecting the wire pairs of the HRE-458 cable stub to the main cable located in the splice
case. The following sections contain step-by-step procedures for:
• Preparing the stubs for splicing into the main cable (pre-splice procedure)
• Splicing the stubs into the main cable (splicing procedure)
• Dressing and taping the final splice in the splice case (post-splicing procedure)
Figure 12. Cable Stub Construction
When using these splicing procedures, be sure to maintain cable pair integrity when splicing stub pairs into the
main cable. Follow local practices as required.
Pre-splicing Procedure
Ground the HRE-458 enclosure before splicing the cable stubs into the main cable. The
grounding method discussed in
“Grounding” on page 11 (or an accepted local grounding
method) must be in effect at all times to safeguard personnel.
The HRE-458 comes with a screened cable stub that is precut and capped.
