4. The device may only be put into service if…<br />
- the information on the type plate of the device is consistent with the approved Ex field of application<br />
on site (device number, category, zone, temperature class or maximum surface temperature).<br />
- the information on the type plate of the device is consistent with the power supply network.<br />
- the device is not damaged (no damages due to transportation and storage) and<br />
- it is made sure that there is no explosive atmosphere, oils, acids, gases, vapors, radiations, etc.,<br />
during assembly.<br />
5. No change may be carried out on equipment used in explosive areas. Repair work may only be<br />
carried out by authorized organizations.<br />
7.2 Additional information about the ignition protection category "Dust ignition-proof"<br />
Foreword:<br />
These installation instructions are intended to guarantee you the safe handling of our product in<br />
explosive areas, especially in dust zones.<br />
english<br />
Marking of the devices:<br />
with EC type examination certificate<br />
Zone 21:<br />
II 2 D Ex tD A21 IP6X T=85°C test number<br />
Protection class labeling: IP 6X for zone 21/Category 2<br />
The following points must be considered for dust ignition-proof devices:<br />
Intended use<br />
1. The increased hazard in explosive areas requires careful compliance with the safety and commissioning<br />
instructions<br />
2. Explosion-proof electrical devices are subject to the standards of series EN 60079 and EN 61241.<br />
They may only be used in explosive areas in accordance with the requirements of the competent<br />
supervisory authority. This authority is in charge of determining the explosion hazard and the zoning.<br />
The ignition protection category, the temperature class are stated on the type plate and on the<br />
EC type examination certificate<br />
– Equipment group II (explosive areas due to dust), category 2 (= zone 21)<br />
3. The mechanical and electrical characteristics such as rotational speed, ambient temperature,<br />
mechanical load, max. supply voltage, etc., of the purchased equipment may in no case exceed<br />
the values permitted by the manufacturer.<br />
4. When mounted, the equipment must have a sufficient mechanical strength.<br />
5. The used elastomer parts, such as the o-rings used for the sealing of the device, are subject to<br />
standard DIN EN 61241-1. The user is to make sure that these sealing elements do not wear prematurely<br />
or are not damaged because of improper influences. This may occur e.g. through direct<br />
UV radiation, aggressive media (acid) or sharp objects.<br />
6. The following standards apply:<br />
General requirements: EN 61241-0: 2006<br />
