Output Circuit
Note: Use the monitoring device(Safety relay module) provided the capavility to
detect a cross short circuit. The insulation of the cable has to withstand
environmental influences. If a control device other than the one shown in the
draft is used, the used control device has to be equipped with a cross short
circuit monitor.
