Troubleshooting
Wiring OK indicator light is not lit.
• Check to make sure that the Power Console is plugged into an
earthed AC wall socket. Do not use any plug adapters.
• This indicates that the live and neutral (L–N) wires are reversed.
Unplug the Power Console and consult an electrician.
For all other technical questions or troubleshooting issues, please
contact Belkin Customer Service 00 800 22355460.
Glossary of Power Terms
Alternating Current (AC): The current that is commonly flowing through
the electrical sockets in your home. It is an electrical current in the form
of a sine wave that oscillates up and down continuously.
Amp: An abbreviation for Ampere. This is a unit of electrical current.
Direct Current (DC): An electrical current flowing in one direction only.
DC current does not have a wave form.
Electromagnetic Interference (EMI): Electrical interference generated
by appliances and many other electrical components that cause
degradation of sound and picture quality in audio and video equipment.
Earth: A conducting object, such as a wire, that is connected to a
position of zero-voltage potential. Common connecting points are earth
rods or cold-water pipes that are connected to the Earth.
Joule Rating: A measure of electrical energy. The higher the joule
rating, the more electrical surges a device can absorb before failing.
Maximum Spike Current: The maximum current (in Amps) that can be
absorbed before failing. The higher the maximum spike current, the
more current a device can absorb without failing.
Radio Frequency Interference (RFI): Electromagnetic radiation, which is
emitted by electrical circuits carrying rapidly changing signals as a
by-product of their normal operation, and that causes interference or
noise to be induced in other circuits.
Spike: A very fast transient variation in voltage or current. Many small
transients, over time, cause components to wear and fail.
Surge: An increase in voltage or current significantly above the
designated level in a flow of electricity.
