1) The auxiliary voltage was disconnected during the first 5 cycles of the test. The auxiliary voltage was
switched on during the sixth cycle when the temperature was +55°C and the humidity 95% Rh.
2) Protection relay was soaked unpowered for 12 hours and then checked for functionality.
3) LCD may be unreadable, but the protection relay is still operational.
4) For protection relays with an LC communication interface, the maximum operating temperature is +70°C.
5) Protection relay was energized.
