8. Installation & Wiring

1. Power Off: Disconnect all system power before installation.

2. Mounting: Snap module firmly onto Momentum backplane; ensure proper grounding.

3. Wiring (Outputs – Triac/230 VAC):

   • Connect line (L1) to module 1L+ terminal.

   • Connect neutral (N) to module 1N terminal.

   • Connect load between OUT terminal and neutral (N).
