V.INSTALLATION OF RECORDING EQUIPMENTU.K.
1.Recording equipment must be positioned in the vehicle in such a way that the driver has a clear view from his seat of the speedometer, distance recorder and clock while at the same time all parts of those instruments, including driving parts, are protected against accidental damage.U.K.
2.It must be possible to adapt the constant of the recording equipment to the characteristic coefficient of the vehicle by means of a suitable device, to be known as an adaptor.U.K.
Vehicles with two or more rear axle ratios must be fitted with a switch device whereby those various ratios may be automatically brought into line with the ratio for which the equipment has been adapted to the vehicle.
3.After the equipment has been checked on installation, an installation plaque must be affixed to the vehicle beside the equipment or in the equipment itself and in such a way as to be clearly visible. After every inspection by an approved fitter or workshop requiring a change in the setting of the installation itself, a new installation plaque must be affixed in place of the previous one.U.K.
The installation plaque must show at least the following details:
name, address or trade name of the approved fitter, workshop or vehicle manufacturer,
characteristic coefficient of the vehicle, in the form ‘w = … rev/km’ or ‘w = … imp/km’,
effective circumference of the wheel tyres, in the form ‘1 = … mm’,
the dates on which the characteristic coefficient of the vehicle was determined and the effective circumference of the wheel tyres was measured.
4.SealingU.K.
The following parts must be sealed:
the installation plaque, unless it is attached in such a way that it cannot be removed without the markings thereon being destroyed;
the two ends of the link between the recording equipment proper and the vehicle;
the adaptor itself and the point of its insertion into the circuit;
the switch mechanism for vehicles with two or more axle ratios;
the links joining the adaptor and the switch mechanism to the rest of the equipment;
the casings required under point (a)(7.2) of Part III;
any cover giving access to the means of adapting the constant of the recording equipment to the characteristic coefficient of the vehicle.
In particular cases, further seals may be required on approval of the equipment type and a note of the positioning of those seals must be made on the approval certificate.
The seals mentioned in points (b), (c) and (e) of the first paragraph are authorised to be removed:
in cases of emergency,
in order to install, adjust or repair a speed limitation device or any other device contributing to road safety,
provided that the recording equipment continues to function reliably and correctly and is resealed by an approved fitter or workshop immediately after fitting the speed limitation device or any other device contributing to road safety or within seven days in other cases. For each occasion that those seals are broken, a written statement giving the reasons for such action must be prepared and made available to the competent authority.
5.The cables connecting the recording equipment to the transmitter must be protected by a continuous plastic-coated rust-protected steel sheath with crimped ends, except where an equivalent protection against manipulation is guaranteed by other means (for example by electronic monitoring such as signal encryption) capable of detecting the presence of any device which is unnecessary for the correct operation of the recording equipment and the purpose of which is to prevent the accurate operation of the recording equipment by short circuiting or interruption or by modification of the electronic data from the speed and distance sensor. A joint, comprised of sealed connections, is deemed to be continuous within the meaning of this Regulation.U.K.
The aforementioned electronic monitoring may be replaced by an electronic control which ensures that the recording equipment is able to record any movement of the vehicle, independent from the signal of the speed and distance sensor.
For the purposes of the application of this point, M 1 and N 1 vehicles are those defined in Part A of Annex II to Directive 2007/46/EC of the European Parliament and of the Council(1). For those vehicles that are equipped with tachographs in compliance with this Regulation and are not designed to be fitted with an armoured cable between the distance and speed sensors and the recording equipment, an adaptor shall be fitted as close as possible to the distance and speed sensors.
The armoured cable shall be fitted from the adaptor to the recording equipment.
Directive 2007/46/EC of the European Parliament and of the Council of 5 September 2007 establishing a framework for the approval of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles (OJ L 263, 9.10.2007, p. 1).
