User manual FURMAN AR20 II

[. . . ] do not place the AR-20 ii near heat sources such as radiators, heat registers, stoves, or other appliances that produce heat. Route the power cord and other cables so that they are not likely to be walked on, tripped over, or stressed. Pay particular attention to condition of cords and cables at plugs, and the point where they exit from the AR-20 II. To prevent risk of fire or injury, damaged cords and cables should be replaced immediately. saFety InFoRmatIon to obtain best results from your Furman AR-20 ii 1 aR-20 II Voltage RegulatoR / poweR condItIoneR 5. [. . . ] With this exclusive filtration technology, all connected equipment will be free of noise and contamination and will operate at optimum performance levels. 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. extreme Voltage shutdown Indicator this Led is normally off. it monitors a hazard common in the entertainment industry: wiring faults ­ for example, accidental connection to 220VAC where 120VAC is expected, or an open neutral from a 208 or 240VAC feed. the Series II 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 1453 Fuses and cIRcuIt BReaKeRs there is one fuse and one circuit breaker in the AR-series. in the event that the unit appears to be completely dead (neither the Power switch nor any LED's light up), unplug the power cord and the load and check the breaker. if the circuit breaker is tripped, a white button will pop up. the purposes of these circuit protection devices are: 1. A fast-blow 20 amp circuit breaker is accessible at the rear panel without removing the unit from the rack. This breaker will trip if the aR-20 II Voltage RegulatoR / poweR condItIoneR unit's 20 amp capacity is exceeded at any time. A fast-blow 1/4 amp fuse is located inside the unit. This fuse will blow if the unit has been connected to a voltage that is above the range of the extreme Voltage shutdown circuitry. To replace it, the unit must be completely disconnected from all power and removed from its rack. the six hex head screws and two Phillips head screws holding the top cover must be removed. the internal fuse is located in a holder on the printed circuit board. Replace the fuse only with the exact same type (1/4 fast blow). InstallatIon Because of their toroidal transformer design, Furman Voltage Regulators may be positioned near most other equipment without fear that the other equipment will be disrupted by leakage of a strong 50/60 Hz magnetic field. Nevertheless, suggested rack locations would be either at the top or bottom. As with any rackmount equipment, be sure to use 10-32 machine screws for mounting in the rack's tapped holes (this is not a metric size). In particular, beware of 10-24 screws, which may fit if forced but which will strip the threads.
