Principper for ledningsvalg og arrangement af eksplosionssikkert elektrisk udstyr

1. Inde i udstyret, forbindelser mellem forskellige komponenter skal bruge kobberkerneisolerede ledninger, som enten kan være standard ledninger eller kabler. This wiring’s insulation needs to adhere to the equipment’s rated voltage criteria, og dens kapacitet til strøm og varmeproduktion skal være i overensstemmelse med etablerede standarder, 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. Imidlertid, it’s imperative that egensikker 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.
