2.4. Protection
2.4.1. Power Supply
The FX Series is protected from continuous over-voltage by a 2A/250V slow break fuse directly
bonded on the 6-wire cable accessory; and it is also protected against transient voltage peaks over
+32V. When the input voltage exceeds 32V, the supply voltage is automatically disconnected in order
to protect the internal electronic components from overvoltage.

The FX Series withstands ESD according to IEC 1000-4-2 requirements for all accessible parts,
except for the RF connector which withstands ESD as follows:

+/- 8kV of air discharge

+/- 4kV of contact discharge
