Precautions For Connecting Bus Cables in Explosion-proof Industrial Loudspeaker Intercom Systems

1. When laying bus cables, environments with strong electromagnetic interference should be avoided.
2. All cables must be clearly marked so that they can be defined when being wired.
3. The wiring sequence of all bus cables must not be confused; they must be properly matched.
4. There must be no terminal points in the middle of the bus cable.
5. The shielding layer of the bus cable must be well grounded.
