1. Binnen de apparatuer, ferbinings tusken ferskate ûnderdielen moatte gebrûk meitsje fan koperen kearn isolearre wiring, dat kin wêze of standert triedden of kabels. This wiring’s insulation needs to adhere to the equipment’s rated voltage criteria, en har kapasiteit foar hjoeddeistige stream en waarmtegeneraasje moat oerienkomme mei fêststelde noarmen, 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. lykwols, it’s imperative that yntrinsyk feilich 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. Standard, unshielded high-frequency wires should not be installed parallel to other wires.
5. Intermediate connections or joints are not permissible on internal wiring.
