SSH IEC 60204-11:2018

Safety of machinery - Electrical equipment of machines - Part 11: Requirements for HV equipment for voltages above 1 000 V a.c. or 1 500 V d.c. and not exceeding 36 kV

Scope

This part of IEC 60204 applies to electrical and electronic equipment and systems to
machines, including a group of machines working together in a co-ordinated manner, which
operate at nominal voltages above 1 000 V AC or 1 500 V DC and not exceeding 36 kV AC or
DC with nominal frequencies not exceeding 60 Hz.
In this document, the term HV equipment also covers the LV equipment forming an integral
part of the equipment operating at high voltage. The requirements in this document primarily
cover the parts operating at high-voltage except where explicitly stated otherwise
This document is a generic safety standard. It does not cover all the requirements (e.g.
guarding, interlocking or control) which are needed or required by other standards or
regulations in order to safeguard personnel from hazards other than electrical hazards. Each
type of machine has unique requirements to be accommodated to provide adequate safety.
This part of IEC 60204 specifically includes, but is not limited to, machines as defined in 3.29
(Annex A lists examples of machines whose electrical equipment can be covered by this
document).
For protection against electric shock from high-voltage equipment, this document refers to
IEC 61936-1. When it comes to low-voltage equipment, this document refers to
IEC 60204-1:2016.
