Example
Which type of protective insulation is used between the bus terminal of the device module in slot
MXI1 or MXI2 and the mains terminal X100?
The separate potential area with the better protective insulation is decisive.
• The separate potential area of the bus terminal of the device module has a "functional
insulation".
• The separate potential area of the mains terminal has a "reinforced insulation".
Result: The insulation between mains terminal X100 and the bus terminal is of the "reinforced
insulation" type.
