Connection
1. Loosen the holding screw and pull the connector out of the
2. After removing the holding screw, insert a flat head screwdriver,
3. Loosen the terminal screws (slotted screws) on the terminal
4. Secure the cord by fastening the ground nut.
When making connections, take note that using other than the
supported size (ø3.5 to ø7) heavy duty cord will not satisfy IP65
(enclosure) standards. Also, be sure to tighten the ground nut and
holding screw within their specified torque ranges.
Changing the entry direction
After separating the terminal block and housing, the cord entry
can be changed by attaching the housing in the desired direction
(4 directions at 90° intervals).
∗ When equipped with a light, be careful not to damage the light
Precautions
Plug in and pull out the connector vertically without tilting to one side.
