silopark,
Only one thing, if you are designing the panel, supplying all the materials, and constructing the unit for sale to a 3rd party to integrate into a machine or other piece of equipment, you must have product liability insurance for the finished goods, along with professional indemnity insurance to cover the design aspects.
Also it must comply with all of the relevant "new approach" directives.
These would typically be the machinery directive, the low voltage directive & the emc directive along with the CE marking directive.
You can either get the equipment externally audited and certified, or you can presume compliance by design and construction to harmonised standards which are covered by the directives.
BE EN 60204-1 being an example, the nearest way I can describe this is the machinery equivalent to the brb.
Remember a lot of the colour codes for the wiring is different for 60204 to 7671.
If you presume compliance and CE mark yourself, you must ensure that if requested you can provide the technical file, this can only be requested by HSE and must contain sufficient relevant technical information for the items you integrate into your product and the design criteria, safety tests and inspections etc.
Will any part of the equipment be safety related?
I suspect so, as it will require an emergency stop to comply with statutory legislation, as the designer of the control system you will need to assess the category of stop system required and provide clear instructions to the integrator on how to implement the safety circuits.
Remember using all CE marked equipment in your panel will not mean that the final unit itself is compliant.
CE+CE does NOT = CE.
Just a brief overview of the legislation etc. not exhaustive as I have to dash.
What would I do, same as i have always done, depending on the application & customer, either design & build it to 60204 deliver it and bank the cheque, or get it CE'd by an external provider. Mark up the checking and sell the package then bank the cheque.
