SERIES II POWER CONDITIONERS
beyond the capabilities of any TVSS device to absorb without some degree of damage. In the rare instance that this occurs, the green �Protection OK� LED indicator located on your front panel will dim. If this happens, some level of protection from voltage surges will remain, but the Furman�s clamping voltage rating will be compromised. The unit must be returned to Furman Sound, or an authorized Furman Service center for repair. NOTE: If the mains power is above the high cutoff voltage and has caused the unit to remove power from its outlets, it cannot restore power without the operator manually turning the unit off, then on again. Avoid turning the unit back on, without first checking the source of the problem, and perhaps changing the AC source. AC receptacle where AC voltage is present. If the problem persists, the protection circuit may be damaged, and require factory service. 3.) Symptom: Extreme Voltage indicator lit. Possible Cause: Input voltage is above 135140 volts (270 � 280 volts E version), causing power to the unit�s outlets to be shut down. Additionally, if the voltage is below 85 - 90 volts at turn on, the unit will not allow AC voltage to reach the outlets. Action Needed: Correct the line voltage, then turn the unit on. Consider installing a Furman voltage regulator.
DEFINITIONS
SPIKE: This is a pulse of energy on the power line. Spikes can have voltages as high as 6000 volts. Though they are usually of very short duration, the energy they contain can be considerable, 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 maintenance operations, lightning strikes and other factors. Spikes (also called surges or transients) are absorbed by special components in the PL-8 and PL-PLUS to provide safe voltage levels to protect your equipment. RFI/EMI INTERFERENCE: Noise from RFI (Radio Frequency Interference) or EMI (Electro

1.) Symptom: No power to the AC outlets. Possible Cause: Circuit breaker has tripped due to excessive load. Action Needed: Remove one piece of equipment from the Series II unit, and push the square re-set tab into the Circuit breaker bezel. 2.) Symptom: No power to the AC outlets, �Protection OK� indicator is not lit. Possible Cause: Either the AC outlet to which your Series II device is connected has no AC voltage present, or the unit has been subjected to a sustained voltage in excess of 400 Volts. Action Needed: Plug the Series II unit into an
