4 General 4.1 Isolation and energy dissipation Machines shall be provided with devices intended for isolation and energy dissipation (see clause 5), especially with a view to major maintenance, work on power circuits and decommissioning (see the essential safety requirement expressed in 1.6.3 of annex A of EN 292-2:1991). 4.2 Other means to prevent unexpected [unintended] start-up If the use of isolation and energy dissipation is not appropriate (e.g. for frequent short interventions in danger zones), the designer shall provide, according to the risk assessment (see prEN 1050), other measures (see clause 6) to prevent unexpected start-up. Additional means such as signalling and/or warning may be appropriate (see annex B). NOTE 1 Examples of tasks which can require the presence of persons in danger zones are given in annex A NOTE 2 According to 5.7.1 of EN 292-1:1991, the designer should as completely as possible determine the different machine operating modes and the need for the presence of persons in danger zones. Appropriate built-in safety measures can then be provided to prevent operators from being induced to use hazardous operating modes and hazardous intervention techniques caused by technical difficulties in the use of the machine (see also 3.12 "Intended use of a machine" of EN 292-1:1991). 5 Devices for isolation and energy dissipation 5.1 Devices for isolation from power supplies 5.1.1 Isolation devices shall:  Ensure a reliable isolation (disconnection, separation);  Have a reliable mechanical link between the manual control and the isolating element(s);  Be equipped with clear and unambiguous identification of the state of the isolation device which corresponds to each position of its manual control (actuator). NOTE 1 For electrical equipment, a supply disconnecting device complying with 5.3 "Supply disconnecting (isolating) device" of EN 60204-1:1992 meets this requirement. NOTE 2 Plug and socket systems (for electrical supplies), or their pneumatic, hydraulic or mechanical equivalents, are examples of isolating devices with which it is possible to achieve a visible and reliable discontinuity in the power supply circuits. For electrical plug/socket combinations, see 5.3.2 d) of EN 60204-1:1992. NOTE 3 For hydraulic and pneumatic equipment, see also 5.1.6 of prEN 982 and 5.1.6 of prEN 983.
