🛡️ Safety & Product Condition

Used product.

Power capacitors may retain a dangerous electrical charge even after the system has been disconnected from the power supply. Before handling, they must be properly discharged and checked using suitable test equipment.

Before use, it is recommended to check:

• Capacitance of all three sections
• Tolerance against the nominal value
• Insulation
• Any abnormal leakage currents
• Condition of the terminals
• Tightness of the connections
• Integrity of the housing
• Any deformation or bulging
• Condition of the connections between the two units

Do not use the components without first verifying their electrical condition and ensuring that no residual charge is present.
