1. The connection of the container to the electrical system must be of a permanent
design. Wall sockets may not be used.
2. The current of the electric system has to be connected to the container through a
two-pole switch with at least 3 mm separation distance between open poles. Such
isolation device must be incorporated in the fixed wire network.
3. The required diameter per core for 3 core mains supply cables: 2.5 mm
subject to the performance indicated on the plate.
Cable types suitable for connecting to the mains:
Suitable types:
Connection with wire protection tube is not allowed.
4. The connection wire and the green/yellow coloured core must be connected in the
serial terminal. To make the connection, remove the screws holding the cover of
the service compartment, and remove the cover. This will expose the electrical as-
semblies. Out of the plastic wire drivers located on the lower part of the service
compartment cover, break the one marked with a label ("Break out for connec-
tion"). Cut the overhanging part of the rubber wire driver located in the bag atta-
ched to the appliance, then stitch the wire driver on the mains cable. Connect the
mains cable in the serial terminal on the left side according to phase label (L, N, E).
Tighten the cable clip and the wire clamp finally, then fit the rubber wire drive to
the lower horizontal surface of the cover frame, in such way that it has to protect
electric parts from any possible water ingress after mounting the cover.
