various safety devices, limit switches, photocells, sensitive rib, stop button.
If one or more of the safety devices are not installed, the corresponding terminals must be short
circuited with the controls common.
All contacts N.C. Assigned to the same input must be connected in series.
All contacts N.O. Assigned to the same input must be connected in parallel.
Provide disconnecting devices in the power supply network in accessible places.
For the power supply of the control unit, there must be an external disconnecting switch (not includ-
ed), independent and properly sized.
