SPO = Static Power Output
SSO = Static Signal Output
The relay has a nonvolatile memory which does not need any periodical
maintenance. The nonvolatile memory stores all events, recordings and logs to a
memory which retains data if the relay loses its auxiliary supply.

Local HMI
The LHMI is used for setting, monitoring and controlling the protection relay and
the related process. It comprises a 7-inch color screen with capacitive touch sensing
and a Home button at the bottom of the LHMI.
The LHMI must be paired with the protection relay to enable all the
functionalities in it. See the operation manual for the pairing procedure.
The LHMI is an accessory for the relay which is fully operational even
without the LHMI.
