Make sure the ground cable is longer than the live cables. In this way it will be the
last wire to be pulled away if the mains cable should accidentally be pulled, and will
thus guarantee the ground connection. Do not use gas pipes to ground electrical
appliances.
A wiring error, as well as impeding the correct operation of the appliance, could also
damage the electrical apparatus that it contains.
MULTIPLE APPLIANCE PLANTS
The appliance must be connected to a 230 V 1N - 50 Hz power supply, as follows (see
example in Figure 5.4 connection to electrical mains (230 V 1N - 50 Hz)
→
45):
You will need: the appliances hydraulically connected; the external electrical panel
configured by the installation technician. Necessary equipment and materials.
Make sure that the electrical panel configured by the technician is equipped with a 2
pole circuit breaker with minimum air gap of 3 mm, and two type T fuses of suitable
rating.
On each appliance, remove the front panel and open the electrical panel by re-
1.
moving the bolts securing it.
For each appliance, provide a FG7(O)R 3Gx1.5 type cable.
2.
Locate terminal block "MC" inside the panel of each appliance and hook up as

shown in the figure.
On completion, restore the appliances to their fully assembled condition.
4.
The insertion of relays or other electrical components inside the General Electrical Pa-
