General Information
Operation
• Use isopropyl or ethyl alcohol on a swab to clean connectors.
Absorbent, lint-free paper wrapped around the end of tweezers is
recommended. Carefully clean the conductive surfaces and avoid
wetting the plastic parts inside the connector with alcohol. After
cleaning, be sure connector is blown dry before re-assembly.
• It is good practice to inspect a connector after cleaning. During the
inspection, check for contaminants and worn plating. Also check for a
misaligned center conductor or spread fingers on the APC-3.5 or
Type-N connectors.
• Support the cable or component attached to the connector.
• When using APC-7 connectors, the nut of one connector should
always be backed off completely and the nut on the mating connector
should be tightened. Never set an APC-7 connector on its mating
surface. Before storage, always screw the nut out to protect the
surfaces.
• Be sure the connectors are axially aligned before the nut is tightened.
• Use a connector gauge periodically to check the center pin depth. The
shoulder of the center conductor must never extend beyond the plane
of the outer conductor mating surface in an APC-3.5 connector.
