Standards expertise

Is the control cabinet for a machine subject to DIN EN 61439-1 or DIN EN 60204-1?

... We frequently supply machine builders with ready-made control cabinets for machines. In this case is the control cabinet a low-voltage switchgear and controlgear assembly in accordance with DIN EN 61439-1? Or must DIN EN 60204-1 be applied?


Standards are always non-binding; they represent the basic tool for complying with the specifications of directives.

In the case described it could be the EMC or Low Voltage Directive.

This question cannot be answered across the board. We have taken two situations by way of example:

1) You are only building the control cabinet (customer has the electrical design).
In this case, the customer must CE certify the control cabinet together with the machine.
2) If the electrical design is on your premises, you must CE certify the control cabinet and supply it with the declaration of conformity in accordance with the Low Voltage Directive and EMC Directive. You CAN apply all relevant standards that are published for both these directives in the Official Journal of the EU.

The exact standard to consider for the installation described and the components used in the control cabinet cannot be clearly determined from afar. Recommendation: A scope is defined in each standard. On this basis, document why a standard has been applied (or why not).
