ELECTRICAL CONNECTION
3
Connection to the electrical power supply must be done according to proper professional practice by a qualifi ed and authorised
person (see current standards and legislation in the country of installation).
If an adapter is used on the socket, a check must be made that the electrical characteristics of this adapter are not lower than
those of the machine.
Do not use multiple plugs
The AC power supply to the machine must comply with the following conditions;
- Maximum voltage variation: ±5%
- Maximum frequency variation: ±1% on a continuous basis, ± 2% over short periods
ATTENTION: the electrical installation must comply (for design, creation and maintenance) with the legal and standard
requirements in the country where used.
- Check that the electric mains voltage, the value shown on the specifi cation plate and the label on the power cable are the
same.
- The machine's electrical power supply must be protected against voltage surges (short-circuits and excess voltages) by using
fuses or thermal relays of the appropriate gauge relative to the place of installation and machine specifi cations – see the spe-
cifi cations shown in column G of fi gure 2.3a
ATTENTION: Concerning protection against indirect contact (depending on the type of power supply provided and
connection of the exposed conductive parts to the equipotential protection circuit), refer to point 6.3.3 of EN 60204-1 (IEC
60204-1) with the use of protection devices for automatic shut-off of power in the event of an insulation fault with a TN or
TT, system, or for the IT system, with the use of a permanent insulation or differentials controller for automatic shut-off.
The requirements of IEC 60364-4-41, 413.1 must apply for this protection.
For example: in a TT system, a differential circuit breaker must be installed upline of the power supply, with a suitable
power cut-off (e.g.: 30 mA) on the earthing installation for the place where it is planned to install the machine.
ATTENTION: Failure to comply with these instructions means the customer runs the risk of machine failure and/or acci-
dents due to direct or indirect contacts.
• Check that the electric mains voltage and the value shown on
the specifi cation plate and the label on the power cable are the
same.
• The machine must be protected by a residual current device
(RCD) and a fuse of a rating shown in column F of the specifi -
cations.
• Motor specifi cations:
A Number of phases (1 single phase or 3 three-phase)
B Nominal voltage in volts (value, range or commutation)
C Frequency (Hertz)
D Nominal rating (Watts)
E Nominal current (Amperes)
F Rating of the fuse protecting the electric line
(Amperes)
1) Dual-voltage three-phase motor.
• A standardised 3-phase + Earth wall socket rated at 20A will
be required and a relevant sealed plug to be fi tted onto the power
lead.
Must be earthed with a green/yellow wire.
• Check the direction of rotation with the ejector fi tted in the
machine.
- Remove the pusher after unlocking it (anti-clockwise direction
).
- Press the "On" button.
- Make a visual check on the ejector's rotation via the pusher
tube. The ejector should turn in an anti-clockwise direction
.
• I f the direction of rotation is reversed, change over the 2 phase
wires on the power socket.
• Connection is made at the upper voltage
To connect at a lower voltage,
follows:
- Disconnect the appliance and turn it over.
- Remove the 4 case retaining screws.

(e.g. 400V).
(e.g. 230V), proceed as
- Change the integral plate wire by moving the cable connection
terminal marked as upper voltage (400V) onto that marked as
lower voltage (230V).
- Change the motor wire connections (see electrical diagram).
- Refi t the casing, then check the direction of rotation.
2) Single phase motor.
A standardised 2-pole + Earth wall socket rated at 10/16A will
be required.
• Warning to the installer:
This electronic variable-speed vegetable slicer is fi tted with an
integral fi lter without going via the variator. To be effective, the
system's earth must be of good quality, otherwise interference
may pass via the variator and damage it.
Must be earthed by green/yellow wire.
• No earth connection = no protection = risk of failure +
DANGER for the user!
Note: The earth values are defi ned according to the residual
differential current (See standard NFC 15100 and PROMOTELEC
guide) and must be checked by an electrician.
Damage caused by a lack of earth will not be covered by
the warranty
In certain cases, depending on the sensitivity of the
protective RCD, SI-type (Super Immunity) devices may
need to be fi tted to prevent unwanted tripping.
To PAT test the Electrolux Range of Food Preparation Equipment,
the PCB board needs to be disconnected before any test is done.
This is due to the fact that the boards are fi tted with a grounding
diode that can give incorrect result during such a test. Also on
a standard appliance a fl ash test of 25 amps and up to 3000v is
used but, as you would expect, to use this on equipment, which
has a printed circuit, board would be quite destructive to that
board. We would recommend the use of a PAT tester approved
for computer systems which use a lower rate of amps.
The appliance is perfectly safe and is CE certifi cated. There are
two ways to get overcome this problem.
· Disconnect the board as instructed and test using test for PC's,
· Or install the mixer on a fused spur (no plug) as this takes it
away from being a portable appliance and the PAT test is then
not needed.
