1. Varustuse sees, erinevate komponentide vahelised ühendused peavad kasutama vasest südamikuga isoleeritud juhtmeid, mis võivad olla kas standardsed juhtmed või kaablid. This wiring’s insulation needs to adhere to the equipment’s rated voltage criteria, ning selle voolu ja soojuse tootmise võimsus peab vastama kehtestatud standarditele, 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. Kuid, it’s imperative that sisemiselt ohutu 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. Standardne, unshielded high-frequency wires should not be installed parallel to other wires.
5. Intermediate connections or joints are not permissible on internal wiring.
