The symbols on the electrical circuits
1 - Location of the relay. The number 12 indicates the location of the relay unit.
2 - Identification unit or element. Designation of the block or element are listed in the specification.
3 - Designation of the fuse. For example: fuse 19 with a current protection 10A
4 - Designation of contacts. For example: Track 3 / 49a. 3 - 3 relay contact 12 on the relay.
5 - Designation of contacts on the relay. A13 indicates a contact terminal 13 A.
6 - cross-section in mm 2.
7 - Color wires. The colors of the wires are shown in wiring diagrams. | 8 - Designation of contact.
9 - unit or element.
10 - Designation of the unit or element and its number.
11 - Continuation of wiring. The number in the box indicates the electrical circuit to which this wire is connected.
12 - Internal connections.
13 - Continuation of the internal electrical connections.
14 - Designation of the grounding point.
15 - Relay and fuse.
16 - External links.
17 - Non-coordinates. Designed to facilitate the search for nodes in the diagrams. |
