Terminal Pinouts
Critical: 10-Pin Power Requirement
This module does not have screw terminals for main power input. It requires a specialized 10-pin power cable connected to the on-board power header:
- P/N 996792: For connection to an Inner Range Smart PSU.
- P/N 996794: For connection to a 3rd Party PSU (Standard DC Input).
