9. d The Series I SMP circuit senses voltages that are so high that operation would be impossible and shuts the power down before damage can occur Upon initially applying power to these units the Extreme Voltage indicator LED will light if the input voltage is above the extreme voltage cutoff and power will not be applied to the unit s outlets If the unit has been operating with an acceptable input voltage and subsequently that voltage exceeds 135V it will shut off power to the outlet and the Extreme Voltage LED will light E version over voltage shut down is 260 VAC Guards against open neutral and accidental connection to 300 VAC Protection OK Indicator Although the Furman SMP circuit assures virtually protection from transient voltage spikes and surges nature has a way of occasionally creating electrical forces that are 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 t
