Single-axis controllers General data and operating conditions 4 4.2 The protective insulation of the 9400 Servo Drives controllers complies with EN 61800-5-1. The following illustration ƒ shows the arrangement of the terminal strips and the separate potential areas of the controller. ƒ serves to determine the decisive protective insulation between two terminals located in different separate potential areas. Bus Ext. DC Protective insulation acc. to EN 61800-5-1 (Definition of terms: see glossary) Functional insulation Basic insulation I/O Reinforced insulation Ext.
DC E94YCXX007 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. ƒ The separate potential area of the device module bus terminal is ”functionally insulated”. ƒ 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.
