user to the presence of important operating and maintenance (servicing)
instructions in the literature accompanying the appliance.
WARNING (If applicable): The terminals marked with symbol of “ ” may be of
sufficient magnitude to constitute a risk of electric shock. The external wiring connected
to the terminals requires installation by an instructed person or the use of ready-made
leads or cords.
WARNING: To prevent fire or shock hazard, do not expose this equipment to rain or
moisture.
WARNING: An apparatus with Class I construction shall be connected to a mains
