Ex Ambient Specifications:
- Operation at Ta = -25 °C up to +60 °C
- Storage at T= -40 °C up to +80 °C
- SIL 1 necessary requirements for the environment e.g. overvoltage category
Ex Installation and Maintenance:
- Use 60079-14 (for dust additional 61241-14) for Project engineering, selection and installation
- Use 60079-17 for Inspection and maintenance
- No repairing of the 140MT-C/D devices allowed (Because Ex protection function is no longer guaranteed!)
- Where automatic restarting after a failure is not permitted, the user must take suitable measures to prevent restarting.
- With the aid of the device's test function, the tripping mechanism can be tested in the de-energized state.
- The cable type and the conductor cross section of the current leads must be selected so that the thermal limiting temperature for the connecting
cables is not exceeded.
- It could be proved in all cases that the motors are safely switched off.
European Hazardous Location Approval. The following applies to products marked II (2) GD and I (M2): Are Equipment Group I and II, Equipment
Category 1G, 2G, 1D, 2D and M2 and comply with the Essential Health and Safety. Requirements relating to the design and construction of such
equipment given in Annex II to EU Directive 2014/34/EU. See the EU declarations of conformity, safety instruction and certificates on links below.
Safety device intended for use outside potentially explosive atmospheres caused by gases,vapors, mist, (coal) dust, and methane are likely to occur
in normal operation, but required for, or contributing, the safe functioning (also during expected malfunctions) of equipment and protective systems
with respect to the risk of explosion. Such locations correspond to Zone 1, Zone 21 and Mining classification according to ATEX directive 2014/34/EU.
