Specification Basis:

DIN EN 62305-3 (VDE 0185-305-3) in the version valid at the time the order is placed;
DIN EN 62305-4 (VDE 0185-305-4) in the version valid at the time the order is placed;
DIN VDE 0100-443 (VDE 0100-443) in the version valid at the time the order is placed;
DIN VDE 0100-534 (VDE 0100-534) in the version valid at the time the order is placed;
DIN VDE 0100-712 (VDE 0100-712) in the version valid at the time the order is placed;

(If, at the time the order is placed, one of the above standards is in a transition period between two versions, the newer version shall apply.)

Optional:
IEC 62305-3 in the version valid at the time the order is placed;
IEC 62305-4 in the version valid at the time the order is placed;
IEC 60364-4-44 in the version valid at the time the order is placed;
IEC 60364-5-53 in the version valid at the time the order is placed;
IEC 60364-7-712 in the version valid at the time the order is placed;

(In the case of IEC standards, there is no transition period between two versions.)


Requirements:

  1. Basic information about the electrical installation
  2. Provision of distribution schematics / circuit diagrams of the electrical installation
  3. Optional: Conducting a fee-based on-site as-built survey / project meeting


Specification:

  1. Dimensioning and provision of the protection goals for the electrical installation / electronic components with the customer (also optional on-site as-built survey)
  2. Creation of a surge protection concept based on the as-built survey or the documents provided
    1. Dimensioning and selection of surge protective devices for the surge protection system, according to the given specifications of the electrical installation to be protected
    2. Graphic representation of the surge arresters used on the component / installation to be protected, based on a distribution board structure diagram
    3. Image documentation with textual description
    4. Creation of a product list of the surge protection components used
  3. Optional: Creating a fee-based design of the external lightning protection system (S19292, S19293, S19294)
  4. Optional: Creating a fee-based design of the earth-termination system for external lightning protection systems (S19295)


Scope:

  1. Definition of the structure to be considered and its properties
  2. Definition of all types of loss for the structure to be considered and the related risks of damage R1, R2, R3 and R4
  3. Assessment of the risk of damage for each selected type of loss
  4. Assessment of the protection requirement by comparing the selected risks of damage (R1, R2 and R3) for a structure with the tolerable risk RT
  5. If R4 is selected: assessment of the economic efficiency of the protection by comparing the costs of a total loss with and without protection measures


Document Format:

  • Handover of all documents electronically in PDF format
  • Handover in open formats (e.g. .docx, .xlsx, .dwg, .nwd) with separate, signed handover document possible
