01. HOW TO READ THE WIRING DIAGRAMS
The wiring diagram is shown divided by individual application, so as make it easier to read
and as straightforward as possible.
Some considerations are valid for all machines, unless otherwise specified. Specifically, the
following should be remembered:
• Each component is identified by a code; the meaning of this code is shown in the key at
the bottom left.
• Each component only describes the identification of the connector used and the pins cor‑
responding to the application in question. The wiring references are shown on the outsi‑
de of the connector.
• Each cable describes the colour or the identifier number. Where the colour is not shown,
the cable is black. Where the number is used, two digits are shown: the first identifies
the wire and is also marked on the wire itself, the second identifies the number of wires
in the cable (e.g.: 14/18=wire number 14 in an 18‑wire cable).
• The Y/G (=yellow and green) wires are always earth wires. The general earth connectors
are located in the control panel, in the control board box and in the mains power supply
box (220V).
