The EC-Type Examination Certificate has to be observed. The special conditions must be adhered to! Directive and hence also EC-Type Examination Certificates apply in general only to the use of electrical apparatus under atmospheric conditions. The use in ambient temperatures of > 60 C was tested with regard to hot surfaces by the mentioned certification authority. If the equipment is not used under atmospheric conditions, a reduction of the permissible minimum ignition energies may have to be taken into consideration. The temperature ranges, according to temperature class, are given in the EC-Type Examination Certificate. Note: Use the temperature table for category!!! The 20 % reduction in accordance with EN 27-:2007 has already been accounted for in the temperature table for category. must be observed. The intrinsic safety is only assured in connection with an appropriate related apparatus and according to the proof of intrinsic safety. The associated apparatus must satisfy the requirements of category ia. Due to the possible danger of ignition, which can arise due to faults and/or transient currents in the equipotential bonding system, galvanic isolation of the power supply and signal circuit is preferable. Associated apparatus without electrical isolation must only be used if the appropriate requirements of IEC are met. Additional requirements for gas group IIB/IIC. Avoid electrostatic charges that can cause electrostatic discharge when installing or operating the device. Information on electrostatic hazards can be found in the technical specification IEC/TS The connection cables should either be fixed when laid and mechanically protected or installed in such a way, that a force of 0 N applied in the direction of the cable inlet for one hour, does not lead to any visible displacement of the cable connections, even though the cable sheathing is displaced, see also IEC Depending on the type of installation, a suitable cable in accordance with Type A oder B of IEC , must be used.
