To reduce risk of electrical shock which could cause personal injury, follow all safety
notices in this documentation.
This symbol warns the user of a potential shock hazard where hazardous live voltages
may be accessible.
• If the equipment is used in a manner not specified by the manufacturer, the protection
protection provided by the equipment must be impaired.
• Do not replace any component (or part) not explicitly specified as replaceable by your
supplier.
• All wiring must be in accordance with local norms and carried out by authorized experienced
personnel.
• The ground terminal must be connected before any other wiring (and disconnect last).
• A switch in the main supply is required near the equipment.
• Mains power supply wiring requires a (T) 0.5A, 250V fuse(s).
DCP551 models sold in September 2013 or later have a built-in fuse.
