Example
Which type of protective insulation is used between the bus terminal of the device module in the
MCI slot and the mains terminal X100?
The separate potential area with the better protective insulation is decisive.
• The separate potential area of the device module's bus terminal is "functionally insulated".
• The separate potential area of the mains terminal has a "reinforced insulation".
Result: The insulation between the mains terminal X100 and the bus terminal is of the "reinforced
insulation" type.
