Select and record the model
Browse the series catalogue, record the exact references and keep the corresponding product images in your shortlist. A complete reference makes it easier to confirm the configuration.
Ask the technical questions early
Request the electrical and installation information for each selected product. Confirm the details against your actual project or distribution requirements.
Bring the commercial brief together
Quantities, destination, packaging and branding should be recorded alongside the product list. The guides here help organize those requirements.
