No power to the AC outlets.
1.) Symptom:
Possible Cause: Circuit breaker switch has tripped to the off position due to excessive load.
Action needed: Reduce the load by unplugging at least one piece of equipment from the unit, reset the breaker/ power switch
to the on position.
2.) Symptom: No power to the AC outlets, "Protection OK" indicator is not lit.
Either the AC outlet to which your unit is connected has no AC voltage present, or the unit has been subjected
Possible Cause:
to a sustained voltage in excess of 400 Volts.
Plug the unit into an AC receptacle where AC voltage is present. If the problem persists, the protection circuit
Action needed:
may be damaged and require factory service.
Extreme Voltage indicator lit.
3.) Symptom:
Possible Cause: Input voltage is above 135-140 volts, causing power to the unit's outlets to be shut down.
Action needed: Correct the line voltage and then turn the unit on. Consider installing a Furman voltage regulator if this is a
common occurrence.
DEFINITIONS:
SPIKE:
A spike is pulse of energy on the power line and can have voltages in excess of 6000 volts. Though they
are usually of very short duration, the energy they contain can be considerable and enough to damage
sensitive solid-state components in audio and computer equipment. Spikes can also foul switch contacts
and degrade wiring insulation. They are an unavoidable component of electric power. They are caused
unpredictably by electric motors switching on or off (on the premises or outside), utility company mainte-
nance operations, lightning strikes and other factors. Spikes (also called surges or transients) are absorbed
by special components in the SMP (Series Multi-Stage Protection) circuitry to provide safe voltage levels to
protect your equipment.
RFI/EMI INTERFERENCE:
Noise from RFI (Radio Frequency Interference) or EMI (Electro Magnetic Interference) involves lower volt-
ages and less energy than is found in spikes, but it is continuous rather than transient in nature. It is not
likely to cause damage, but it can certainly be annoying, producing static in audio circuits, "snow" on video
screens, or garbled data in computers. Noise can be introduced into AC lines by nearby radio transmitters,
certain kinds of lighting, electric motors, and other sources. Because noise occurs at higher frequencies
than the 50 or 60 Hz AC line, it can be effectively reduced through use of low-pass filtering.
