Electrical Installation Rules; Equipotential Connection - La Cimbali S39 Use And Installation

3. Electrical Installation Rules

Prior to installation, make sure there is a circuit breaker installed with a distance between the contacts
that allows for complete disconnection when there is a category III overload and that provides
protection against current leakage equal to 30 mA. The circuit breaker must be installed on the power
supply in compliance with installation rules.
Solenoid valves supplied by a class 2 Transformer: voltage 24 V dc, 0.54 A. Milk sensors supplied by a class 2 Transformer:
voltage 5 V, 10 mA.
The electrical safety of this machine is only ensured when it is correctly connected to an ef cient earthing system in
compliance with the electrical safety laws in force. This fundamental safety requirement must be veri ed. If in doubt,
request that a quali ed electrician inspect the system. The manufacturer cannot be held responsible for any damage
caused by the lack of an earthing system on the electrical supply.
Do not use adaptors, multiple plugs, and/or extension cords.
Check that the type of connection and voltage correspond with the information on the nameplate.

4. Equipotential Connection

This type of connection, required by some laws, prevents differences in the electric potential level between the earthing
connections of equipment installed in the same room.
This machine is provided with a clamp underneath the base for connection to an external equipotential cable.
After installation, this type of connection MUST be made:
• Use a cable with a nominal section in compliance with the laws in force.
• Connect one end of the cable to the clamp and the other end to the earthing of adjacent equipment.
Failure to follow this safety norm releases the manufacturer from any responsibility for machine breakdowns or damage
to people or property.
NOTE: DO NOT CONNECT TO THE POWER SUPPLY EARTHING BECAUSE IT IS NOT CONSIDERED AN
EQUIPOTENTIAL CABLE CONNECTION.
Bear in mind that Gruppo Cimbali S.p.A. is not
responsible for damage caused by improper
electrical connections, and that the installer is
responsible for any damage.
