The table on page 3 indicates compatibility and suggested pairings for isolator switches with different boards and ambient temperatures. Accessories like GW 70 040 and GW 70 041 are also mentioned.
Diagrams on pages 3, 4, 8, 9, 13, 14, 18, 19, 20, 21, 25 show various rotary isolator switch models, their dimensions, and their integration into the distribution boards. These include exploded views and assembly steps.
Installation Procedures
The installation involves several key steps:
- Board Selection: Choose the appropriate board model (Polyester, Metal, Stainless Steel) based on IP rating and environmental conditions.
- Isolator Switch Mounting: Mount the selected rotary isolator switch into the distribution board. This typically involves attaching a shaft, securing the switch mechanism, and ensuring correct alignment.
- Wiring: Connect the electrical circuits according to the specific voltage and current requirements, referencing diagrams for terminal connections and configurations (e.g., 3P/4P, AC21A/AC22A/AC23A ratings).
- Door Assembly: Install and operate the board door, which may have specific opening mechanisms (Views A and B on pages 4, 9, 14, 22 show door operation).
- Shaft and Handle Assembly: Assemble and attach the operating shaft and handle, ensuring correct length and torque specifications (e.g., Max 1.5Nm, M8 15-22 Nm, M10 30-37 Nm).
- Final Checks: Verify all connections and ensure the installation meets safety standards.
Specific torque values are provided for various connections, such as M4x8 screws (1 Nm), M5x10 screws (2.5 Nm), and M8/M10 bolts for shafts.
The 'T' dimension calculation for shaft length is provided in tables on pages 7, 12, 17, 24, relating the shaft length 'A' to the board code.
Detailed step-by-step diagrams are provided throughout the manual (e.g., pages 5, 7, 8, 10, 11, 12, 13, 15, 16, 17, 18, 20, 21, 22, 23, 24, 25) illustrating the assembly of isolator switches, shafts, handles, and their integration into the distribution boards.
Important Notes
The installer is fully responsible for the operations described in this installation manual, including drilling for cable entry and positioning of cable glands. It is essential that the work is carried out with care and precision, as the quality of the installation depends entirely on the installer.
Upon completion of the work, the installer must issue a declaration of conformity for the low voltage switchgear and controlgear assemblies in their own name. Additionally, they must apply a label to the assembled product, indicating the technical data in accordance with technical standards and applicable local laws.
