Installation & Maintenance
Use ESD protection when handling to avoid static damage.
Verify AC input voltage is within 200–230 V range before powering on.
Check LED indicators (PWR, OK, ALM) for normal operation.
Clean dust from the heat sink and vents every 6 months.
Ensure adequate cabinet ventilation (avoid overheating).
Back up system parameters before replacing the module.
