📖 Product Usage Instructions
- 🛠️ Power Isolation: Always verify that system power supplies and connected field loops are completely de-energized and locked out before installing, wiring, or extracting the terminal block.
- 🔌 Secure Engagement: Align the terminal block carefully with the front connector interface of the corresponding I/O module, pressing firmly to ensure complete pin insertion and mechanical locking.
- 🔧 Wiring & Torque Control: Connect field signal and power wires to the individual screw terminals, adhering strictly to supported wire gauges (14–22 AWG single or 16–22 AWG dual) and applying proper tightening torque to prevent loose connections.
- 🧪 Loop Verification: Inspect terminal screw tightness and verify channel mapping against loop diagrams before restoring system power and initiating software diagnostics.
