Safety Instructions
Power off and wait ≥5 minutes for capacitor discharge before service.
Use anti-static wrist strap to avoid ESD damage.
No hot-plugging of power or fiber cables.
Do not modify onboard circuits or jumpers.
Installation
Shut down main power and lockout/tagout.
Mount the board in the designated slot and secure screws.
Connect 3-phase AC input, DC bus output, FSSB fiber, and 24V auxiliary power.
Verify all connectors are fully seated and locked.
Restore power and check LED status; test for normal operation.
Maintenance
Clean dust from PCB and connectors quarterly.
Inspect connectors for looseness, corrosion, or aging.
Check LED fault codes during operation; address alarms promptly.
Keep cabinet dry and free of oil mist.
Troubleshooting
No LED power: Check 3-phase AC input and 24V auxiliary supply.
Overvoltage alarm: Verify input voltage; check regenerative resistor.
Overcurrent alarm: Inspect DC bus short circuit or amplifier fault.
FSSB communication loss: Reconnect fiber; check for damage or bend radius.
