After deciding the direction of the nipple, screw in only the seal nut until it is completely locked at the surface of the limit switch, so that the nipple is firmly tightened onto the limit switch body.

Unscrew the nipple no more than 360˚ to position it in the desired direction.

Screw in the nipple until it contacts the threads of the limit switch.

Screw in the seal nut until it firmly contacts the nipple.

PRECAUTIONS FOR USE

5

The PA1-�G can be added onto the sealed connector (PA1 Series) after the connector is mounted on the limit switch. Attach the cable grip as shown below.

Step 1. Loosen the tightening nut of the sealed connector.Step 2. Pull out the cable.Step 3. Remove the tightening nut of the sealed connector from the cable, and pass the cable through a cable grip of the

appropriate O.D. instead.Step 4. Run the cable into the switch and wire it to the terminal.Step 5. Fully tighten the nut of the cable grip.
