–
–
}
Use appropriate wiring to exclude short circuits between the outputs!
}
The actuators may be connected using unshielded cables.
}
The outputs do not need suppression for inductive loads.
}
Use copper wiring.
}
The terminal configuration as stated on the front plate applies for base modules with C-
rail. The terminal configuration as stated in the technical documentation applies for all
other base modules.

Mechanical connection of the base modules
Procedure:
}
Use a flat blade screwdriver (DIN 5264-A)!
