IEC\/EN 60204-1<\/strong>, This is the fundamental harmonized standard that defines the safety of electrical, electronic, and programmable equipment in machines and machine groups. It sets out the most critical requirements against risks such as electric shock, fire, arc, and unexpected movement, from the design and manufacture of machines to their periodic inspection during operation. (Current edition) EN 60204-1:2018+A1:2025<\/strong>\u2018'tir and EU Machinery Regulation (EU) 2023\/1230<\/a> It provides a presumption of electrical compliance within this scope.<\/p>\n

What does IEC\/EN 60204-1 cover?<\/h2>\n

Standard; rated supply voltage Not exceeding 1000 V AC or 1500 V DC<\/strong>, This standard applies to machine electrical equipment with a nominal frequency of up to 200 Hz. Almost all stationary and mobile industrial machines, excluding hand-held tools, are included; this includes production lines, presses, CNC machines, conveyors, robot cells, packaging and process machines. The standard covers power circuits, control circuits, protection measures, conductor selection and marking, documentation, and pre-commissioning verification tests<\/strong> It addresses them under a single umbrella.<\/p>\n

Exclusions include the portion of the power supply network up to the machine, high-voltage equipment, and certain special machines with their own specific vertical standards; in these cases, the C-type standards belonging to the product family take precedence.<\/p>\n

Basic safety requirements<\/h2>\n

Feed separation device (main switch)<\/h3>\n

Each machine must have its power safely switched off during maintenance and repair. lockable<\/strong> A feed separation device that provides this function must be present. This requirement applies to the facility. power cut-off and lockout (LOTO)<\/a> It also forms the basis of their applications.<\/p>\n

Protection against electric shock.<\/h3>\n

Protection against direct contact (enclosure, insulation, IP protection class) and protection against indirect contact (automatic power cut-off, protective coupling) are provided together. In low-voltage control circuits. PELV<\/strong> Protective low-voltage measures such as these are preferred.<\/p>\n

Protective bonding and continuity (PE)<\/h3>\n

All conductive bushing components must be connected to a continuity-verified protective coupling circuit (PE). The protective conductor cross-section and the main equipotential coupling busbar are sized according to current carrying and fault withstand capabilities \u2014 this with our main grounding \/ equipotential busbar cross-section tool<\/a> You can check it beforehand.<\/p>\n

Emergency stop and emergency shutdown<\/h3>\n

The standard defines the emergency stop function with two stop categories: Category 0<\/strong> (stopping by directly and immediately cutting off the power) and Category 1<\/strong> (Power cut-off after controlled deceleration). Emergency stop devices must be easily accessible from each operator position, red and yellow in color, and have a latching mechanism.<\/p>\n

Conductor identification and marking<\/h3>\n

Conductors are identified by color and\/or number; shielding conductor green-yellow<\/strong>, The neutral part is marked in light blue. Correct marking is essential for maintenance safety and fault diagnosis.<\/p>\n

Mandatory tests and verification (Article 18)<\/h2>\n

EN 60204-1 requires the following verification tests before the machine is commissioned and when changes are made to the electrical equipment. AES Innovation performs these tests with calibrated devices, following the method and sequence prescribed by the standard:<\/p>\n

    \n
  1. Continuity of the protective coupling circuit (18.2.2):<\/strong> Verification that the PE circuit is continuous and remains at low resistance. Details: continuity tests<\/a>.<\/li>\n
  2. Insulation resistance (18.3):<\/strong> Between power circuit conductors and PE 500 V DC<\/strong> Measurement with; the result is at least 1 M\u03a9<\/strong> should be. Limit values insulation resistance from our vehicle<\/a>, however, the aging trend polarization index (PI)<\/a> Check it from your vehicle.<\/li>\n
  3. Voltage (dielectric) test (18.4):<\/strong> Verification of insulation strength by applying twice the rated voltage, or greater than 1000 V AC, for approximately 1 second.<\/li>\n
  4. Protection against voltage fluctuations (18.5):<\/strong> Verification that the voltage in touchable conductors has been reduced to a safe level after the power is switched off.<\/li>\n
  5. Functional tests (18.6):<\/strong> Checking that safety functions, including guard devices, interlocks, and emergency stops, are working.<\/li>\n<\/ol>\n

    Note: The threshold values above are based on EN 60204-1 Clause 18; the sequence and values to be applied according to the machine type and existing pressure will be confirmed under field conditions.<\/em><\/p>\n

    The Machinery Regulations and its relation to EN ISO 12100 and CE.<\/h2>\n

    EN 60204-1 constitutes the electrical component of the machinery safety legislation and is not sufficient on its own; mechanical and functional risks are also addressed. EN ISO 12100 risk assessment<\/a> This is considered. Compliance with EN 60204-1 as a harmonized standard, Machinery Regulations 2023\/1230<\/a> and in terms of electricity in light of relevant national legislation presumption of conformity<\/strong> provides; test records and technical file, CE marking<\/a> It is an inseparable part.<\/p>\n
