Installation & Maintenance

Installation：

1. TRICONEX  3503Emodule is installed vertically on standard Tricon 3000 series rack with good ventilation.

2. Check module appearance and ports before installation, wire strictly according to original terminal definition.

3. Support online hot‑swap; module replacement can be done without shutting down the whole system.

4. Powered by 24VDC industrial power supply with proper grounding to reduce electromagnetic interference.

5. After installation, run system self‑test to ensure normal communication and no fault alarms.

Maintenance

1. Regularly check module status, indicators and communication via built‑in fault self‑diagnosis function.

2. Keep rack and module clean and dry to avoid dust, oil and moisture corrosion.

3. Avoid frequent power‑off plugging; replace modules by hot‑swap to keep SIS/ESD system continuous operation.

4. Check firmware version regularly and upgrade strictly in accordance with manufacturer standards.

5. Store in dry environment when not in use; perform power‑on test before reuse.
