Notes:
If the unit contains copper ports, the IEEE 1613 conformance is Class 1 (During
disturbance errors may occur but recovery is automatic).
If the unit contains all fiber ports, the IEEE 1613 conformance is Class 2 (During
disturbance no errors will occur).

Note:
Class 2 refers to “Measuring relays and protection equipment for which a very high
security margin is required or where the vibration levels are very high, (e.g. shipboard
application and for severe transportation conditions).”
