2. ELECTRICAL CONNECTION NOTE: All the connecting cables that enter the terminal compartment of the UFC 500-EEx signal converter (i.e. power supply, current and binary in-/outputs cables) are not intrinsically safe ! The arrangement of the terminals in the terminal compartment is shown in Figure 1 below. For mains voltages above 50 Vac the PE conductor must be connected to the PE-terminal in the terminal compartment. -
