1. INTRODUCTION
Terminating Head 58246--1 (shown in Figure 1) is
designed to terminate discrete wire in MTA--100 IDC
closed--end receptacle connectors with lock (ramp)
and with lock and polarizing tabs. Slotted contacts for
insulation displacement termination are pre--
assembled on 2.54--mm [.100--in.] centerlines in each
color--coded housing for a specific wire size.
The head must be installed in Pistol Grip Manual
Handle Assembly 58074--1 or Pistol Grip Pneumatic
Handle Assembly 58075--1. For head installation and
removal, refer to Instruction Sheet 408--6790 for the
manual handle assembly and 408--6789 for the
pneumatic handle assembly.
For detailed connector description and application
requirements, refer to Application Specification
114--1019.
Read these and all referenced instructions thoroughly
before using the head.

2. DESCRIPTION
The head serves as a guide and support for the
connector during termination. Features of the head
(shown in Figure 1) and their function are as follows.
Wire Inserter — forces the wire into the two slotted
beams of the contact. Note that it provides support for
the contact beams when applying insertion force on
the wire.
Adjuster (Insertion Rod) — is a piston for the wire
inserter and regulates wire inserter travel.
Feed Slide — automatically positions the connector
after each termination.
Locating Pawl (or Anti--Backup Pawl) — aligns the
connector for insertion, and retains it during
termination.
3. SETUP AND TEST INSPECTION
The adjuster (insertion rod) is preset for wire sizes 28
through 22 AWG. If the wire is being inserted too
deeply or not deeply enough inside the contact, it may
be necessary to adjust the depth of the wire inserter
or, in addition, if the pneumatic handle assembly is
being used, it may be necessary to adjust the air
pressure. Proceed as follows:
3.1. Setup
1. Determine the wire size, and select the
