GENERAL SAFETY NOTES
1 GENERAL SAFETY NOTES
As an additional safety measure, the use of a residual current device (RCD), also called a ground fault circuit interrupter (GFCI), in the repair centre is highly recommended.
Risk of fatal electrical shock and fire! Mains voltage inside the coffee machine.
Unplug appliance before cleaning.
Never clean wet or immerse plug, cord or appliance in any fluid.
Disconnect the mains plug before disassembly - the appliance must be free of voltage.
This device does
not protect against electrical shock due to contact with both circuit conductors.
Example illustrations
of typical devices.
Use a GFCI with a trip
level of 4 - 6 mA (USA)
resp. a RCD with a trip level of 15 - 30 mA (Europe). A trip level above 30 mA provides only very limited protection against harm from an electric shock.
1) RCD protected socket-outlet
2) Plug-in RCD unit
3) GFCI socket
4) Plug-in GFCI
Danger of burns! Hot parts and water under pressure inside the coffee machine
(particularly in the thermoblock).
Let coffee machine cool down before cleaning or disassembly.

Protective earth continuity measurements are made between the protective earth terminal of the power plug and the thermoblock casing.
This test assures that
- the ground (earth) connection does not have an interruption between the power plug and the thermoblock
- the permissible ground resistance is less than 0.3 Ohms (with a test current of 200 mA DC).
Test equipment
Special test equipment is needed that complies with the regulations to perform protec­tive earth continuity measurements. Detailed requirements and tolerances must be veri­fied by your local authorities or measurement supplier in any case.
Test report
For legal reasons a repair or test report should be prepared and filed with following infor­mation
- customer (name, address)
- type and serial number of coffee machine
- date of repair/test(s)
- performed test(s)/measuring value(s)
- used test equipment
- signature
Ask Nespresso for recommendations about test equipment.

8.6.4 What to do if the protective earth continuity test fails
Check/measure ground wire connection of power cord; replace if necessary.
Check/measure ground connection terminal on thermoblock. Retighten terminal screw if necessary.
8.7 Protective insulation test
8.7.1 What is the protective insulation test about?
This test is necessary
- for class 1 and 2 equipment (with/without protective earth)
- after a repair whenever a general disassembly was performed.
8.7.2 General
Legal regulation
In case of a repair/modification of the coffee machine, the repair centre is bound by law to protect the user/consumer by
- restoring the regular condition of the appliance and
- performing the respective tests according to EN/IEC 60335-1 “Safety of household and similar electrical appliances” and national regulations (e.g. DIN VDE 0701).
Description
The insulation test
- assures that wiring and insulation of the coffee machine fullfill the normative require­ments after a repair,
- rates the insulation capability of the coffee machine,
- is a very dangerous test because of a high test voltage (500 V DC).
For the insulation test, phase and neutral wire are shunted at the power plug. Then a test voltage is applied between phase/neutral and selected parts of the coffee machine.
Test equipment
Special test equipment is needed that complies with the regulations to perform insulation and withstanding voltage tests. Detailed requirements and tolerances must be verified with your local authorities or measurement supplier in any case.
Ideally the test equipment has a national power socket for testing, so that the coffee machine can plugged in directly. Otherwise a special shunt is necessary to connect the phase and neutral pin of the coffee machine’s power plug.
Test report
For legal reasons a repair or test report should be prepared and filed with following infor­mation
- customer (name, address)
- type and serial number of coffee machine
- date of repair/test(s)
Perform the protec­tive earth (PE) conti­nuity test at first, if it is
mandatory.
Ask Nespresso for recommendations about test equipment.
