7. Information on mounting and operation in hazardous areas

WARNING!

Non-observance of these instructions and their contents may result in the loss of

explosion protection.

The requirements of the 94/9/EC (ATEX) directive must be followed. Additionally

the specications of the respective national regulations concerning Ex usage

(e.g. EN/IEC 60079-10 and EN/IEC 60079-14) apply.

■

The responsibility for classication of zones lies with the plant operator and not the

manufacturer/supplier of the equipment.

■

The plant operator guarantees, and is solely responsible, that all thermometers in use are

identiable with respect to all safety-relevant characteristics. Damaged thermometers may

not be used.

■

For the installation of the thermometer, only components (e.g. cables, cable glands, etc.)

permitted for “ameproof” may be used.

■

For earthing the conductive screen, follow the specications of EN/IEC 60079-14.

■

When using a transmitter/digital display, note and follow:

- The contents of these operating instructions and those of the transmitter/digital display

- The relevant regulations for installation and use of electrical systems

- The regulation and guidelines regarding explosion protection

■

The ameproof thermometers should only be tted to certied housing- or connection

heads certied with a “ameproof” ignition protection type.

■

For tting, the permitted ameproof joints for electrical equipment for gas hazardous

areas are contained in EN, IEC 60079-1. Flameproof joints

for parallel threads

, must

be ≥ 5 mm for housing volumes < 100 cm³ and ≥ 8 mm for housing volumes > 100 cm³.

There must be ≥ 5 threads engaged.

Flameprooof joints

for tapered threads

, must have ≥ 5 available threads on each part.

There must be ≥ 3.5 threads engaged. These specications for ameproof joints must be

adhered to, without fail, when tting and during operation.

■

The direct threaded connection of the thermometer to the connection head or housing

must not be twisted or opened. Any alignment of the housing may only be made using the

optional “nipple-union-nipple” neck tube.

■

The temperature resistance of the connecting cable must match the permissible operating

temperature of the housings.

For ambient temperatures above 60 °C, heat-resistant connecting cable must be used.

■

No batteries may be built in to the ameproof housing.
