2 Safety requirements and installation instructions
2 Safety requirements and installation instructions
2.1 Installation instructions
2.2 Intrinsic safety
– The device is associated equipment with an EPL [Ga], [Da] (category 1) of the ignition protection
type "intrinsic safety" and can be installed as a device with the EPL Gc (category 3) in the potentially
explosive area of Zone 2. The intrinsically safe electrical circuits can be routed up to Zone 0 /
Zone 20. It meets the requirements from the following standards.
EN 60079-0, EN 60079-11, EN 60079-15
For detailed information, please refer to the declarations of conformity.
– The installation, operation, and maintenance must be carried out by personnel with electrotechnical
qualifications. Follow the described installation instructions.
– Adhere to the applicable conditions and safety regulations (including national safety regulations)
and the general rules of engineering during set-up and operation.
– Observe the safety information, conditions, and limits of use specified in the product documentation.
Comply with them.
– Opening or modifying the device is not admissible. Do not repair the device yourself; instead, you
should replace it with an equivalent device. Repairs must only be performed by the manufacturer.
The manufacturer is not liable for damage resulting from violations of this.
– The protection type IP20 (IEC/EN 60529) of the device is intended for a clean and dry environment.
Do not expose the device to any mechanical and/or thermal stresses that exceed the described lim-
its.
– Only use the device up to a pollution degree of 2 according to IEC 60664-1.
– The connected, non-intrinsically safe electrical circuits must have a maximum overvoltage
category II according to IEC 60664-1.
– The device must be taken out of operation if it is damaged, has been improperly stressed or stored,
or malfunctions.
– The device complies with the EMC regulations for industrial areas (EMC class A). It may cause EMC
problems if used in residential areas.
– The products must be installed according to all relevant standards for electrical systems in poten-
tially explosive areas.
– Only use copper cables as connecting cables.
– The device is approved for intrinsically safe (Ex i) electrical circuits up to Zone 0 (gas) and Zone 20
(dust) of the Ex area. The safety technology values for intrinsically safe equipment and the connect-
ing lines must be observed for the hook-up process (EN 60079-14) and the values specified in this
installation note and/or the EU examination certificate must be observed.
– During measurements on the intrinsically safe side, make sure to observe the valid conditions rele-
vant to the interconnection of intrinsically safe equipment. Only use the approved measuring devic-
es in intrinsically safe electrical circuits.
– If the device has been used in non-intrinsically safe electrical circuits, using it again in intrinsically
safe electrical circuits is prohibited! Clearly mark the device as not intrinsically safe.
