Electrical installation
General
The machine has been designed for connecting to the electrical network according the specification of your order.
Before connection check the electrical data stated on the data plate, if they correspond to your electrical
network. An individual branch circuit needs to be used for each machine. The way of the connection is
described in figure 27. For electrical protection, there must be installed a residual current device (RCD)
and a circuit breaker in the electrical installation of the building (laundry switchboard).
For correct selection see below.
IMPORTANT:
If the machine is not equipped with a main switch then supply disconnecting devices need to be provided
in the installation for all electrical supplies connected to the machine, in accordance with EN 60204-1 standard,
point 5.3.
Make sure the supply voltage is always within the limits specified in the chapter “Technical data”
in all circumstances. When you have long distances in the electrical installation, it may be necessary to use
bigger cables to reduce the voltage drop.
When the machine is connected near a large capacity power supply transformer (500kVA or more, wiring
length shorter than 10 m) or there is a power capacitor switch-over, a power supply improving reactor
must be installed. If you do not install this, the inverter may get damaged. Contact your sales office for more
info.
WARNING!
GROUNDING: IN EVENT OF MALFUNCTION OR BREAKDOWN OR LEAKAGE CURRENT, THE GROUNDING
WILL REDUCE THE RISK OF ELECTRICAL SHOCK AND SERVE AS A PROTECTING DEVICE,
BY PROVIDING A PATH OF LEAST RESISTANCE OF ELECTRICAL CURRENT.
THEREFORE IT IS VERY IMPORTANT AND THE RESPONSIBILITY OF THE INSTALLER TO ASSURE
THE WASHER IS ADEQUATELY GROUNDED AT THE POINT OF INSTALLATION TAKING
INTO CONSIDERATIONS THE NATIONAL AND LOCAL CONDITIONS AND REQUIREMENTS.
1. Residual current device (RCD)
2. Laundry electrical switchboard
3. Supply protection device
4. Washing machine
5. Phase conductors
6. Protective conductor
7. Main switch inlet terminal switchboard
8. Neutral conductor
