FAQs
What does the surge protection indicator light mean?
The surge protection indicator light shows that the surge protection circuitry is active and functioning. If this light turns off, it means the surge protection has been used up due to one or more power surges, and the unit should be replaced to ensure continued protection.
Can I use this surge protector outdoors?
No, this surge protector is designed and intended for indoor use only. Exposure to moisture or outdoor elements can damage the unit and pose a safety hazard.
How often should I replace this surge protector?
While the unit has a lifespan, the most critical indicator for replacement is the surge protection indicator light. If this light is off, the protection is gone, and the unit must be replaced. It's also advisable to replace it if it shows any signs of physical damage or malfunctions.
What is the maximum power this surge protector can handle?
The SMJ S4WI2C has a maximum load of 3120 watts. Ensure that the total power consumption of the devices plugged into it does not exceed this limit.
Are the sockets protected against children?
Yes, all four sockets are fitted with child safety covers. These covers prevent foreign objects from being inserted into the sockets and protect against accidental contact with live terminals.
Can I plug any type of electrical appliance into this extension lead?
You can plug most standard indoor electrical appliances, provided their combined wattage does not exceed the 3120-watt maximum. Avoid plugging in high-power devices that could overload the unit, such as high-wattage heaters or industrial equipment.
Troubleshooting
Device connected to a socket is not receiving power.
Check if the individual switch for that socket is turned on. Ensure the appliance itself is functioning correctly by testing it in another socket.
Power indicator light is off.
Ensure the surge protector is plugged in securely to a working mains socket. Test the mains socket with another device. If the socket is working and the light is still off, the surge protector may be faulty.
Surge protection indicator light is off.
If the surge protection indicator light is off, it means the surge protection has been exhausted. The unit will still function as an extension lead, but it no longer offers surge protection. Replace the unit immediately to ensure continued protection for your appliances.
Overheating or unusual smells.
Immediately disconnect the surge protector from the mains power socket and unplug all connected appliances. Do not use the product. Contact the manufacturer or a qualified electrician.
