Scope

This standard is applicable to the terminal markings of valve device stacks, devices and the main circuit of the overall inverter equipment assembled by the factory. The terminal markings are aimed at stacks, devices and equipment composed of semiconductor valve devices. Note: This standard does not consider the auxiliary circuit including the gate terminal, the non-integral assembly of the converter equipment, its parts are manufactured separately, and the connection between them is only carried out at the time of field installation. For such equipment the relevant standards for the individual components apply. The purpose of this standard is to specify a logical alphanumeric marking system for the marking of main circuit external terminals in stacks, valve device units or integrally assembled solid-state converter equipment. The marking system is suitable for circuit diagrams, product catalogs, instructions and exchanged and archived materials. The marking method adopted is based on IEC145. In the case of stacks and installations, an alphanumeric marking system is used to mark those variable flow connections considered in IEC 971, and those connections which are the most important and frequently used, also for the marking line given in the example in Clause 5. made with identifiers from the same publication. This standard does not include a terminal marking system identified by graphic symbols and colors. Note: The marking of the terminals of the auxiliary circuit should be clearly identifiable.
