Installation and Wiring

Before you begin

• Always disconnect power before wiring. Work only if you are qualified to handle mains electricity.
• Verify the module ratings match your system voltage and expected load.

Basic wiring steps

• Mount the module securely in an insulated enclosure to prevent accidental contact.
• Run the live conductor through the current sensor or connect through the shunt as specified in your module documentation.
• Connect the AC supply to the module’s voltage input terminals and the load to the output terminals as directed by the wiring diagram.
• Reconnect power and verify readings on the digital output before full operation.
