3. Setup Instructions
- Unpack the Surge Protector: Carefully remove the surge protector from its packaging. Inspect it for any visible damage.
- Choose a Location: Place the surge protector on a flat, stable surface, away from sources of heat or moisture. Ensure the 6-foot cord can reach a wall outlet without being stretched or kinked.
- Connect to Wall Outlet: Plug the surge protector's power cord directly into a grounded 3-prong AC wall outlet. Do not plug the surge protector into another surge protector or an extension cord.
- Verify Protection: Once plugged in, the green 'Protected' indicator light on the surge protector should illuminate. This indicates that the surge protection circuitry is active and functioning correctly. If the light does not illuminate, refer to the Troubleshooting section.
- Connect Devices: Plug your electronic devices (computers, monitors, printers, etc.) into the available AC outlets on the surge protector.
Important Safety Information:
- Do not exceed the electrical rating of the surge protector (120V, 15A, 1875W).
- This device is intended for indoor use only.
- Do not use in wet environments or near water.
- Do not open the surge protector casing. There are no user-serviceable parts inside.
4. Operating Instructions
Powering On/Off:
The surge protector features a master power switch. Press the red switch to the 'ON' position to supply power to all connected outlets. Press it to the 'OFF' position to cut power to all connected devices. This switch also acts as a circuit breaker.
Understanding the Indicator Light:
- Green 'Protected' Light ON: Indicates that the surge protection components are active and your connected equipment is protected from surges and spikes.
- Green 'Protected' Light OFF: Indicates that the surge protection components have been compromised or have absorbed a significant surge, and the unit no longer provides surge protection. In this event, the surge protector should be replaced.
Resetting the Circuit Breaker:
If the surge protector experiences an overload (too many devices drawing too much power), the built-in circuit breaker may trip, cutting power to the outlets. To reset, first unplug some devices to reduce the load, then press the 'RESET' button located near the power switch. The power switch should then be turned 'ON' again.
5. Maintenance
The Kensington Guardian Premium Surge Protector requires minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:
- Cleaning: Disconnect the surge protector from the wall outlet before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or abrasive materials.
- Inspection: Periodically inspect the power cord and the surge protector for any signs of damage, such as frayed wires, cracks, or discoloration. If damage is found, discontinue use and replace the unit.
- Indicator Light Check: Regularly check the green 'Protected' indicator light. If it is off, the surge protection is no longer active, and the unit should be replaced to ensure continued protection for your devices.
