* When working with electrical connectors, make sure that the isolation between the ports is maintained, see "Isolation
between ports".
Note
ISO tolerance and punching burr
For dimensions without tolerance details, the general tolerances "medium" acc. to DIN ISO
2768 apply. No punching burrs are permitted.
Isolation between ports
SCALANCE XR524-8C has four port groups:
● Group 1: P1 - P4 and P13 - P16
● Group 2: P5 - P8 and P17 - P20
● Group 3: P9 - P10 and P21 - P22
● Group 4: P11 - P12 and P23 - P24
The requirements of the isolation voltage for Environment A (IEEE 802.3) are met between
ports of the same group, in other words, the electrical isolation of the ports is designed for
500 Vrms (1 minute). Example: between P1 and P15
The requirements of the isolation voltage for Environment B (IEEE 802.3) are met between
ports of different groups, in other words, the electrical isolation of the ports is designed for
1500 Vrms (1 minute). Example: between P6 and P23
