Setup, Compatibility & Care
Installation should be performed by qualified personnel. Ensure all main power is disconnected before beginning work on the electrical board. The module is intended for use with compatible Legrand distribution board systems. When wiring, strip the conductor to the appropriate length for the screw terminal, ensuring no exposed copper extends beyond the terminal block. Regularly inspect the connections during scheduled maintenance intervals to ensure that thermal cycling hasn't loosened the screw terminals over time.
