BL20 modules are suitable for installation and operation in confined spaces. The minimum distance
to any passive components should be 10 mm/0.39 inch. Should the adjoining component be an
active element (for example load-current supply, transformers), then a minimum distance of 75
mm/2.95 inch must be kept, to comply with EMC regulations and to prevent overheating. If neces-
