1.1 ISO7021 and ISO7021F Device Construction Information

The components being certified comply with IEC 60079-0 Edition 7 and IEC 60079-11 Edition 6. When one of these components is used in equipment, the component is soldered onto a PCB inside a suitable enclosure and reevaluated as equipment. The creepage and clearance distances across the isolating component have been evaluated, but the distance to other circuitry remains the end-equipment user's responsibility.

When the component is fitted in intrinsically-safe equipment, a 500V Routine Dielectric Strength Test must be conducted in accordance with clause 6.3.13 of IEC 60079-11:2011.

This assembly is an isolating component between separate, intrinsically-safe circuits. The assembly must be connected to suitable, certified, intrinsically-safe circuits, and consider the following entity parameters:
