2.9. ELECTRICAL CONNECTION
The assembly, installation and connection of these cabinets must be
carried out by a certified technician.
Before obtaining access to terminals, all supply circuits must be
disconnected.
Consult the circuit diagrams that are supplied with each cabinet when carrying out
the electrical connections and observe all of your country’s safety regulations in
full.
For the electrical connection it is mandatory to incorporate a switch
disconnector in accordance with installation regulation. This switch has
to be directly connected to supply terminals and has to be able to
provide full disconnection in all poles under overvoltage Category III
conditions.
Before plugging into the mains, check that the supply voltage is the same as the
voltage indicated on the nameplate. The electricity supply should be adequate for
maximum consumption.
