Technical data according to IEC/EN 60079-7 (increased safety "eb"):
IECEx / ATEX Terminal and Cross-Connection Arrangements:
- cross section, American Wire Gauge
- Stripping length
Max voltage data according to IEC/EN 60079-7 in conjunction with
protective earth terminal blocks of the A-Series, (increased safety "eb"):
A - Continuous no difference between one or two cross connections
Note:
If smaller cross sections than the rated cross section are used, the belonging lower current has to be laid
down in the IECEx/EC-Type Examination Certificate of the complete apparatus.
Application Case
Information for further cross-connector arrangements will be provided on request.
F - Next to a protective conductor terminal (earth) with end plate
H - Cross-connection with twin parallel
C - Adjacent – separated by an end plate no difference between one or two cross-connections
D - Intermediate - bridging one or more unconnected terminals (e.g. every 3rd terminal) no
difference between one or two cross connections
