Foundation Fieldbus terminal voltage
All of the following voltages are terminal voltages directly at the device:
Version
Minimum terminal voltage
Maximum terminal voltage
Standard
9 V
32 V
Ex ia (FISCO model)
9 V
17.5 V

Potential equalization
Please observe the following points to ensure maximum EMC protection:
• Ground the device via the external ground terminal. The cable should be kept as short as
possible for optimum electromagnetic compatibility. Ideally, use a ground strap.
• The shielding of the bus cable must be continuous and intact.
• If there is potential equalization between the individual grounding points, ground the
shielding at each cable end or connect it to the device housing (keep as short as
possible).
• If there are large differences in potential between the individual grounding points, only
one point is connected with the reference ground. All the other ends of the shielding are
connected to the reference potential via a capacitor that is suitable for high frequency
use (e.g. ceramic capacitor 10 nF/250 V).

CAUTION
‣
In applications that are subject to explosion protection regulations, the protective shield
may only be grounded at multiple points under certain conditions, see IEC/EN
60079-14.
