GB 46038-2025 Electrical equipment and system of industrial machines—Safety requirements English, Anglais, Englisch, Inglés, えいご 1 Scope This document specifies the safety requirements for electrical equipment and system of industrial machines, including basic safety requirements, electrical system safety requirements, control system safety requirements, and safety protection requirements. This document is applicable to the design, manufacturing, production, use and maintenance of electrical, electronic and programmable electronic equipment and system of machines (including a group of machines working together). This document is applicable to the electrical equipment or their components that operate with nominal supply voltages not exceeding 1,000V a.c. or 1,500V d.c., and with nominal frequencies not exceeding 200Hz. Additional requirements are required for electrical equipment or their components operating at higher nominal supply voltages or higher frequencies. Note: Examples of equipment within the scope of this document are given in Annex A. This document does not apply to: ——electrical equipment used in explosive environment; ——electrical equipment used for radiological and medical purposes; ——electrical parts and components of elevators for goods and personnel; ——instruments; ——electrical equipment specific for ships, aircraft or railways; ——equipment identical to household and similar household appliances. 2 Normative references The following documents contain provisions which, through reference in this text, constitute provisions of this document.
