Figure 2.25.1 – Assignment of seven-pin socket terminals with an additional re-

ceiver to connect a portable lamp.

To control the working process of coupled machines, it is possible to install control equip-

ment (control consoles), which belongs to the coupled machine.

Coupled machines are equipped with various electrical and electronic units, the activity of

which can influence the readings of tractor instruments. Thus, the used electrical instru-

ments shall have a certificate of electromagnetic compatibility according to international

requirements.

Connect electrical equipment of coupled machines to the following elements of trac-

tor electrical equipment:

1. Seven-pin socket (type 12N, GOST 9200, figure 2.25.1) – permissible input current is

not higher than 10A, the electrical circuit is protected by a fuse in tractor electrical equip-

ment:

- "+" to terminal No.5 of the socket;

- "–" to terminal No.3 of the socket (it is possible to connect the coupled machine

electrical consumer when the parking lights of this machine are on).

2. Two-pin socket (ISO 4165:2001), located on the body of the seven-pin socket (figure

2.25.1).

- (terminal No.8) – permissible input current is not higher than 12A, the electrical cir-

cuit is protected by a fuse in tractor electrical equipment;

3. Tractor generator.

- "+" to terminal "В+" of the generator

- "–" to the engine housing.

ATTENTION: WHEN CONNECTING THE ELECTRICAL EQUIPMENT OF IMPLE-

MENTS COUPLED WITH THE TRACTOR, CONTACT YOUR DEALER AS WRONG
