These are related to the distributed leakage current system of the SCM1 Series.

• Ensure correct connection of the insulation detection unit module to the control mother, closed mother, and ground wire to prevent damage.
• Do not reverse connect A and B of RS485 to avoid communication failure.
• Ensure A and B of each small current sensor correspond to A and B on the module's terminal block.
• Connect the mother detection branch from detection branch 1 first, then to the control mother detection branch.
• In corrosive environments, seal joints, bolts, and lead wires to prevent corrosion and dust.
• Install and use the sensor without deformation, avoiding heavy objects and heat sources.
