Installation options for the temperature multi-input device in the hazardous area
Observe the EC-type-examination certificate or the statement of conformity. Pay particular
attention to any "special conditions" that may be indicated.
Danger!
Explosion hazard from wrong calculation of verification of intrinsic safety
If you do not consider the maximum permissible peak values of all components when
connecting intrinsically safe devices with intrinsically safe circuits of associated apparatus, this
can lead to added currents or voltages. This, in return, can result in a current/voltage flashover
generating sparks. The sparks can ignite the surrounding potentially explosive atmosphere.
Ensure you observe IEC/EN 60079-14 and IEC/EN 60079-25 for the verification of intrinsic
safety.
Danger!
Explosion hazard from inadequate or missing separation appliance
If you fail to apply the required separation appliance, e. g. a separation wall, between an
intrinsically safe and a non–intrinsically safe circuit, this can result in a current/voltage flashover
generating sparks. The sparks can ignite the surrounding potentially explosive atmosphere.
Ensure you apply the required separation appliance in order to meet the requirements
according to IEC/EN 60079–11.
