3.6 Electrical connection
Instructions for a proper electrical connection of the espresso coffee machine:
• Before connecting the unit to the electrical mains, make sure that the data on the data
plate corresponds to the electrical mains.
• The tag is located on the left side of the machine (and can be accessed by removing the
lower tray).
• The electrical system provided by the client must comply with current standards. The
power socket must be equipped with a working earth connection. LA SAN MARCO
SPA will not in any way be held liable if legal requirements are not met. An improper in-
stallation can cause injury or damage for which the manufacturer cannot be held liable.
• For the electrical connection, it is necessary to install an omnipolar main switch upstre-
am of the power supply; this switch should be rated according to the electrical cha-
racteristics (power and voltage) shown on the rating tag. The omnipolar switch must
disconnect the power supply with a contact gap of at least 3 mm.
• If it is necessary to use adapters, multiple plugs and extensions, only products meeting
applicable safety standards must be used.
• To avoid any overheating of the power cable, unwind it completely.
