1. Iekārtas iekšpusē, savienojumiem starp dažādām sastāvdaļām jāizmanto vara serdeņa izolēta elektroinstalācija, kas varētu būt standarta vadi vai kabeļi. This wiring’s insulation needs to adhere to the equipment’s rated voltage criteria, un tā strāvas plūsmas un siltuma ražošanas jaudai ir jāatbilst noteiktajiem standartiem, similar to the requirements for intrinsically safe electrical devices.
2. Wires within the equipment must be routed to avoid any contact with parts that are either high-temperature or mobile.
3. Internal wiring should be tidily arranged and securely bundled. Tomēr, it’s imperative that iekšēji drošs wiring is not bundled together with other types of wires. ‘Tidily arranged’ implies that each wire in the bundle should avoid crossing or tangling with others.
4. Standarta, unshielded high-frequency wires should not be installed parallel to other wires.
5. Intermediate connections or joints are not permissible on internal wiring.
