Tightening the Cover
The cables are held between the sealing section cover and sealing section
housing to ensure resistance to splashing.
For cables with smaller outer diameters, the sealing pieces can be used to
ensure splash resistance.
The range of outer diameters of cables that can be connected is 2.2 to
6.3 mm. When the diameter is within the range of 2.2 to less than 3.6 mm,
then the sealing section for small-diameter cables must be attached.
1. Expand the split in the sealing piece and insert the cable.
2. Place the groove on the sealing pieces onto the inside of the housing to
secure it. (See following diagram.)
For terminals that are not connected, insert an NC pin into the small cable
sealing piece as shown in the following diagram. Then secure the sealing
piece onto the housing as described above.
Finally, close the cover and tighten the cover screws.
The tightening torque is 0.8 to 1.0 N·m.
