VI. Installation and Maintenance Guide
1. Installation Notes
The controller should be installed in a well-ventilated environment free of corrosive gases.
Ensure stable power supply voltage and proper grounding.
Ethernet cabling should be routed away from sources of strong electrical interference.
2. Battery Enable Procedure
Ensure the controller is powered off.
Locate the SW10 switch on the side.
Set the switch to the closed position (pins 1-4 closed).
Restore power; the system will automatically recognize the battery status.
3. Routine Maintenance
Regularly check status LEDs to ensure normal operation.
Clean ventilation openings to prevent dust accumulation and overheating.
Periodically back up system configurations to prevent data loss.
4. Troubleshooting
Connect a diagnostic tool to the COM1 port to retrieve system logs.
Use Ethernet status LEDs to determine network connection status.
In case of system lock-up, use the front panel reset switch to restart.
