10 meters (30 feet) or more of wire between the 

electrical outlet and electrical service panel. 
This device features an internal protection that 

will disconnect the surge protective component 

but will maintain power to the load – now 

unprotected. if this situation is undesirable for 

the application, follow the manufacturer’s 

instructions for replacing the device.

TROUBLESHOOTING

If the Protected indicator does not light, the 

surge protector’s AC line is no longer protected 

from surge. Replace the surge protector. The 

surge protector may have received a power 

surge or spike beyond its specified limits that 

overloaded the protection circuitry and 

rendered it inactive. The surge protector has 

protected your connected equipment but it will 

not protect against future surges and spikes.
