EN 60204-1 for machinery defines PELV for itself and does not even use SELV.
-Dave -----Original Message----- From: John Woodgate [mailto:[email protected]] Sent: Thursday, November 23, 2017 2:00 AM To: [email protected] Subject: Re: [PSES] Safe powering 12V doorlock There is no definition of PELV because the definition of 'SELV circuit' does not prohibit a connection to earth, as other definitions of SELV do. Also see Note 2: NOTE 2 This definition of an SELV CIRCUIT differs from the term "SELV system" as used in IEC 61140.
