Power Supply Cable Connection (Replacement); Type Of Connection To The Mains - eka MKF 464 S Translation Of Original Installation And Maintenance Manual

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
minimum section of 2.5mm
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
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 mm²).
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.

3.9 Type of connection to the mains

400V 3PH + N ~
Connect the 3 phase conductors (L1, L2, L3) of the cable respectively to the terminals of the terminal board
marked with "1"(brown conductor), "2"(black conductor) and "3"(grey conductor) and the neutral (N)
conductor to the terminals marked with "4" or "5" (blue conductor); the earth conductor (yellow/green)
must be connected to the terminal marked with the symbol
board).
230V 3PH ~
Connect the 3 phase conductors (L1, L2, L3) of the cable respectively to the terminals of the terminal board
marked with "1" and "2" (brown conductor), with "3" and "4" (black conductor) and with "5" (grey
conductor); the earth conductor (yellow/green) must be connected to the terminal marked with the
symbol (see diagram available by the terminal board).
230V ~
Connect the conductor of phase (L) of the cable to the terminals of the terminal board marked with "1",
"2" and "3" (brown conductor) and the neutral (N) conductor to the terminals marked with "4" and "5"
(blue conductor); the earth conductor (yellow/green) must be connected to the terminal marked with the
symbol (see diagram available by the terminal board).
