17、trolled Copy, (c) BSI EN 50 042 BSI 07-19993 1 Scope This standard applies to switching devices which are able to operate only when completed with external associated electronic circuit components and contacts. The rules in this standard apply only to terminals for external associated electronic cir
18、cuit components and contacts. These are a supplement to the general rules for the marking: of control supply terminals (see EN 50 005, clause 3.1), and of terminals for internal auxiliary contact elements (see EN 50 005, clause 4.2). The use of this standard is recommended where terminal marking is
19、a requirement of the relevant standard for switching devices or is usual practice. 2 Marking of terminals for external associated electronic circuit components and contacts Terminals for external associated electronic circuit components and contacts shall be marked in the following alpha-numerical m
20、anner. 2.1 Marking of terminals for external associated impedances 2.1.1 The two terminals for an external associated impedance Z shall be marked Z1 and Z2. 2.1.2 For an impedance Z with tappings, the terminals for the tappings shall be marked in sequential order Z3, Z4, etc. 2.1.3 In case of more t
21、han one impedance, the terminals shall be marked by using the letter Z and two-figure numbers, the first figure being a sequence number.
