Safety and Availability of the H-S81-HS System General Description
1.3.6 Electromagnetic Compatibility (CE)
The H-S81-HS system has been designed and tested for resisting to standard levels of radiated and
conducted electromagnetic interference, and electrostatic discharges. The table below lists the types
and levels of the tests undergone by the H-S81-HS system.
1.4 Safety and Availability of the H-S81-HS System
The H-S81-HS system is intended for use in applications requiring a high safety level, together
with high system availability. According to the required safety and availability levels, different
H-S81-HS system configurations can be provided.
