Replacing the power cable
The power cable connection to the terminal block is of
the “Y” type: the flexible cable can only be replaced with
the use of a special tool that the service technicians
have.
When replacing the power cable only use H05V2V2-F
T90 type cables suitable for the load and operating tem-
perature. Also, the yellow/green earth wire must be
approx. 2 cm longer than the phase and neutral wires
(Fig. 13).
After connection, test the heating elements by operat-
ing them for about 3 minutes.
To open the terminal block cover and access the con-
nection terminals, proceed as follows:
●
insert the tip of a screwdriver in the protrusions on the
visible side of the terminal block;
●
press lightly and prise upwards (Fig. 14).
