We all purchase Ex installations, and we specify, design, install, commission, operate, maintain and repair it according to:
- Manufacturer’s Ex certification, manual and list of accessories
- Functionality
- hazardous area classification
- explosion protection documentation / Verification Dossier
As long as we take them 1:1, no problem.
BUT if we do any modification related to:
- Ex protection
- Functionality
- List of accessories
- Manual
- …
We immediately may become a manufacturer of that one piece of Ex installation.
Follow up is simple I have to behave like a manufacturer, there is a need for:
- Ex unit/type certification
- Own declaration of Conformity
- Own manual
- List of accessories
- Own label
- …
Make sense to avoid becoming a manufacturer.
Keep up good work!
Ps.: if there is a Ex service facility, we might have another option…
