3.7 Electrical connection
The appliance’s connection to the electric power network and the connection systems must comply with the
applicable regulations in the country of installation. Before setting up the electrical connection ensure that:
the voltage and frequency of the power supply system match the specifications of the "technical data" plate
affixed to the side of the appliance;
the power supply system is able to withstand the appliance's load (see "technical data" plate);
the power supply system is fitted with an effective earthing connection according to the regulations in force;
in the permanent connection to the electric power network, a protective pole switch must be placed
between the appliance and the mains (e.g. circuit breaker) with minimum opening between the contacts of
overvoltage category III (4000V) and a differential switch, sized for the load and complying with applicable
regulations.
the protective pole switch used for the connection is easily accessible when the appliance is installed;
the yellow/green earthing cable is not interrupted by the switch;
when the appliance is running, the power supply voltage does not deviate from the rated voltage value by
±10%.
Ensure that the power supply cable does not come into contact with the appliance's hot parts.
If the power supply cable is damaged, it must be replaced by the manufacturer or their technical support
service, or in any case by a person with similar qualifications, to prevent any risk.
The appliance must be connected to an equipotential system the effectiveness of which must be suitably
assessed according to applicable regulations. This connection must be set up between appliances through
the suitable terminal which is marked with the symbol
. The equipotential conductor must have a
minimum section of 2.5mm
2
.
The equipotential terminal is on the back of the appliance (see the attached “Technical Data Sheet”).
3.8 Power supply cable connection (replacement)
The appliance is fitted with a power supply cable
(
except for models
MKF 1664 TS and MKF 2011 TS
)
connected to the internal terminal board; if it needs to be replaced with a longer one or because it is
damaged, it can only be done with another cable having the same electrical characteristics (insulation
type/number of conductors/size of conductors in mm
²
).
Remove the back and/or the left side of the appliance to access the power supply terminal board. Loosen the
cable retainer located on the rear (at the bottom) of the appliance (see the attached “Technical Data
Sheet”). Disconnect the power supply cable from the terminal board and remove it from the relative cable
gland. Insert the new power supply cable in the cable gland up to the terminal board. Prepare the
conductors for the connection with the terminal board so that the earth conductor is the last to be extracted
from its terminal should the cable be accidentally pulled.
The cable connection must be type "Y" and the insulation of the cable sheath must match type H07RN-F.
The correct section of the cable is shown on the diagram of the power supply terminal board, according to
the type of connection between appliance and mains (The cable must match the features in the attached
"Technical Data Sheet").
When connected, tighten the cable retainer on the back of the appliance and reassemble the left side and/or
the back.
