What must be ensured when installing Class 1 circuits with adjacent power supply circuits?

When installing Class 1 circuits near adjacent power supply circuits, it is crucial that functionality association must exist. Class 1 circuits are low voltage circuits that are designed to operate within specific electrical parameters and are typically less than 30 volts. These circuits are often used for communication systems, signaling, and similar applications.

Establishing a functional relationship between Class 1 circuits and adjacent power supply circuits ensures that their operations are compatible and do not interfere with each other. This association allows for integrated systems where power supply and control or communication functions can work seamlessly together, improving overall efficiency and minimizing the risk of malfunctions or failures due to improper installations.

Maintaining the correct relationship between these circuits not only promotes safety but also enhances system reliability, as it ensures that the circuits can operate harmoniously without issues arising from their proximity to higher voltage systems.
