6.6. Maintenance of electrical system
Attention
Before taking any action on electrical
components disconnect the machine from the
mains.
Always carefully check the isolating covers, the clamps
and the grip of the sheaths;
seal gaskets cannot
guarantee the IP level of protection declared by the
manufacturer if they are not correctly positioned or if
they are damaged.
Replace sheaths and cables if their isolating covers are
ruined or damaged.
Check and restore, if necessary, the identification
labels and stickers of the wires and of the components
keeping to the indications shown in the electrical
diagrams.
Make sure that the identification plate of the electric
panel (see section 1.9) and the adhesive electric
hazard plaque (see section 2.3) are perfectly legible
and firmly attached; otherwise replace them by
requesting new ones from the manufacturer.
The replacement of faulty control components must
always be carried out according to the norms in force,
using components with technical characteristics
complying with those of the components that need to
be replaced.
Use exclusively original SELMI spare parts
The manufacturer will take no responsibility
for accidents or damages in the case o
fuse of non-original spare parts.
