4. Components Overview

Figure 1: Front view of the Erico TDX200M277/480 Modular TDX Panel Protector, showing the indicator panel and wiring conduit.

The front panel of the TDX Panel Protector provides visual indicators for its operational status:

• Voltage Presence LEDs (L1, L2, L3): Indicate that voltage is present on each respective phase.
• Protection Status Light: Illuminates to indicate that the surge protection function is working correctly.
• Surge Counter: Displays the number of surge events the device has protected against.
• RED-REPLACE Indicators (L1-G, L1-N, L1-L3, L2-G, L2-N, L2-L3, L3-G): These indicators correspond to individual surge protection modules. If any of these show 'RED-REPLACE', the associated module requires replacement.

5. Installation (Setup)

Installation of the Erico TDX200M277/480 Panel Protector should only be performed by a qualified electrician in accordance with all applicable national and local electrical codes.

1. Power Disconnection: Ensure all power to the electrical panel where the device will be installed is completely disconnected and locked out.
2. Mounting: Mount the protector securely to a suitable surface near the electrical panel, ensuring adequate clearance for wiring and ventilation.
3. Wiring: Connect the device to the electrical system according to the wiring diagram provided with the product. Pay close attention to phase (L1, L2, L3), neutral (N), and ground (G) connections. The built-in disconnect and fusing simplify the wiring process.
4. Verification: Double-check all connections for tightness and correctness before restoring power.

6. Operation

Once properly installed and powered, the TDX Panel Protector operates automatically. Monitor the front panel indicators for operational status:

• Normal Operation: The Voltage Presence LEDs (L1, L2, L3) should be illuminated, and the Protection Status Light should be on, indicating active surge protection. All RED-REPLACE indicators should be clear (not red).
• Surge Event: In the event of a surge, the device will divert excess voltage. The Surge Counter will increment, indicating a successful protection event.
• Module Failure: If a surge module has failed or reached its end of life, the corresponding RED-REPLACE indicator will turn red, and an audible alarm may sound.

7. Maintenance

The Erico TDX Panel Protector is designed for minimal maintenance. The primary maintenance task involves replacing surge modules when indicated.

• Module Replacement: If any RED-REPLACE indicator is active, the corresponding surge module needs to be replaced. This can be done easily due to the modular design. Always disconnect power before attempting module replacement. Refer to the detailed replacement instructions provided with the replacement modules or consult a qualified technician.
• Periodic Inspection: Periodically inspect the device for any visible damage, loose connections, or unusual sounds.
