This surge board is a direct replacement for components within the following automation platforms:
| Automation Series | Specific Kits/Platforms | Power Center Type |
|---|---|---|
| PL4 / PSL4 Series | Automation Control Systems | Integrated SCG Centers |
| Personality Kits | i5+3 Systems | Load Centers |
⚠️ Critical Electronics Warnings
- Voltage Verification: Verify the transformer is outputting 30–35V AC. If transformer power is good but the salt cell is dark, this board has likely failed.
- Grounding Check: Ensure the green grounding wire is securely bonded to the enclosure to enable the surge protection circuitry.
- Seating Connectors: Align multi-pin adapters carefully before applying pressure to avoid bending the header pins on the new PCBA.
- Seal the Enclosure: Ensure all conduit openings are sealed to prevent moisture from bypassing the board's protective anti-corrosion coating.
