Work Procedure
1. Pass the cable through the components in this order : 1. cable bushing, 2. plug body, 3. clamp fitting. Then perform
the cable end processing.
2. Solder the wires to the P shell unit.
3. Align the protruding portion of the clamp with the recessed portion of the P shell unit and mount.
4. Align the plug and cable sheath strip position, then tighten the plug body to the screw portion of the P shell unit
with a torque of 1
N•m.
Note that to prevent loosening, an application of Locktight 263 manufactured by HENKEL JAPAN LTD. is
recommended.
5. Put the cable bushing over the clamp body to complete the job.

Work Procedure
1. Pass the cable through the components in this order : 1. cable bushing, 2. plug body. Then perform the cable end
processing.
2. Solder the wires to the P shell unit.
3. Fasten the clamp fitting to the cable with the cable crimping tool (HR10A-TC-04).
4. Tighten the clamp body to the screw portion of the P shell unit with a torque of 1
N•m.
Note that to prevent loosening, an application of Locktighe 263 manufactured by HENKEL JAPAN LTD. is
recommended.
5. Tighten the set screw so that the tip falls into one of the two bosses of the clamp fitting.
Note that a tightening torque of 0.3
N•m.
is specified.
6. Put the cable bushing over the clamp body to complete the job.
