Guidelines
The following tips are recommended when preparing
and terminating the 3M cable 7700 series.
Preparation
• Take care to keep the new cut edge of 3M cable
7700 series perpendicular to the outer edge
of the cable for easier termination to connectors.
• Do not allow blades to slice or scrape into
polyolefin insulation.
• Cycling step five 2-3 times may aid removing
the foil covering for increased conductor count
cable samples.
Termination
• Push connector outer wall flush against covering,
but leaving a minimal gap of exposed
ribbon cable.
• Do not allow foil covering to connect to insulation
displacement contacts.
• To maintain 3M socket assembly 451 series integrity,
excess foil covering must be removed for clearance
under socket assembly ears.
Inspection
• Insulation of exposed ribbon cable should not be
scrapped or sliced. See Figure 13.
• Any remaining foil covering on sides of prepared
cable should be removed. See Figure 14.
• Insulation around the conductors should not
be pierced. See Figure 15.
