SPEEDCON wiring method
The M12 connector can be mated with a SPEEDCON connector.
Set the projected portion of the cable connector metal ring (plug /socket) to the mark at cable end.
Push the connector straight to insert it into the receptacle of the unit. If inserted without aligning the mark,
the connector will not mate with the receptacle.

Turn the connector clockwise. It stops when turned 1/4 turn. Turn it further. When the connector is turned
1/2 turn from the original position, the projected portion is set at the diagonal position to the mark and the
turn is completed. Check that the connector is securely locked. If the connector is turned excessively, it
will become difficult to remove.
