6. Operating Instructions
6.1 Powering On/Off
To power on the connected equipment, press the Power/Reset switch on the front panel to the ON position. To power off, press the switch to the OFF position.
6.2 LED Indicators
- Surge LED (Green): When illuminated, it indicates that the surge protection feature is active and functioning. If this LED is off, the surge protection has been compromised, and the unit should be replaced.
- Ground LED (Green): When illuminated, it indicates that the PDU is properly grounded. If this LED is off, there may be a grounding issue with your power source or the PDU itself.
6.3 Circuit Breaker
The Power/Reset switch also functions as a circuit breaker. If an overload occurs, the switch will trip to the OFF position, cutting power to all connected devices to prevent damage. To reset the circuit breaker, reduce the load on the PDU and then press the switch back to the ON position.
7. Maintenance
7.1 Cleaning
To clean the PDU, ensure it is powered off and disconnected from the main power source. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or aerosols.
7.2 Regular Checks
- Periodically check the Surge and Ground LEDs to ensure they are illuminated, indicating proper function and grounding.
- Inspect the power cord and connected device cords for any signs of damage or wear.
- Ensure all connections are secure.
