and disconnect power before removing cover because 90 V a.c. can be accessible.
Equipment connected to the protective earthing of the building installation through the mains
connection or through other equipment with a connection to protective earthing – and to a cable

below a certain frequency range (galvanic isolator, see EN 60728-11).
