NUMZER CPSES QI-QP-11.3-49 3 APR 9 1984 2 of 4 The QC Inspector shall inspect the installation of CONAX feedthrough/ adapter module assemblies in accordanca with this instruction and sign and date the operational traveler QC Inspection Points.

The QC Inspector shall inspect the installation of CONAX feedthrough/ adapter module assemblies to the latest revision of all referenced docunents.

3.1 INSTALLATION 3.1.1 Preparation for Installation of Adapter Module Assemblies Drawings of the adapter module shall be available during installation, Reference 1-C.

Remove adapter modules one at a time as needed.

CAUTION: During handling of adapter assemblies, use extreme care not to abraid, scuff, or cut the conductors insula tion. If conductor insulation has been damaged, it may be repaired using Raychem WCSF-N tubing, or Engineer approved equal .

CAUTION: Do not exceed the minimum bend radius for conductors, Reference Paragraph 3.1.3 of this Instruction Parts for the installation of each adapter module assembly are packed with the module in the same carton. Inventory ,

the parts per the top assembly drawing (7060-10000) and pa rts lists. Report any discrepancies to Electrical QE.

Visually inspect each adapter module assembly to make certain no damage has occurred during shipment or storage.

Inspect the surface finishes of the penetration header port and adapter module body per Detail A of the top assembly drawing (7060-10000).

Remove the caplug (Conax P/N N-49006-17) installed in the pressure monitoring hole of the adapter module body.

3.1.2 Installation of Adapter Module Assemblies Install the Conax Feedthrough/ Adapter module assembly into the penetration per the Anphenol Sams instruction manual except as modified below:

CAUTION: Do not allow polar onjanic solvents such as Ketones (MEK), chlorinated h or aromatic hydrocarbons (Acetone)ydrocarbons to come in direct contact with or permit open containers in close proximity to the adapter modules as these materials may cause irreparable damage to the conductor seals. Clean , adapter module s, wi th denatured alcohol or Freon TF.

Install the outside containment "Q" seals onto the adapter module prior to installing the support bushings on the feedthrough tube.

Position the support bushing (s) of the adapter module on the feedthrough tube to ensure that it (they) will be centered in approximately the middle of the penetration conductor support when the module is installed.

During installation, ensure that the set screws of the eccentric conductor support bushings of the module align radially within 15* of the axial center of the penetration per view B-B of the module assembly drawing (7060-10000).

Module pigtail conductors shall be supported a maximum of 36 inches from the penetrating header plate or conductor suppo rt.

3.1.3 Minimum Bend Radius The minimum inside bending radius of the module conductors is 10 times its insulated diameter for conductor sizes

  1. 16 AWG through #10 AWG and 6 times its insulated diameter for conductor sizes #8 AWG through #2 AWG.

Conductor sizes larger than #2 AWG and Coax /Triax cables are rigid and shall not be bent except when the adapter module must be separated to gain clearances between conductors.

For this exception, cables shall not be bent more than 1" from the axial centerline of the module (13/4" maximum

' from each other) as shown on the detail of the top assembly drawing (7060-10000).

CAUTION: Do not overbend cable. Do not attempt to bend cables more than once since the conductor of the module may be damaged. Report discrepancies to Electrical OE.
