User manual FURMAN RI1210

[. . . ] Precision digital AC voltmeter monitors incoming AC line voltage. Static discharge AC ground circuit for high-elevation installations. · · · · · · Description In the home theater/audiophile domain, the need for clean, noise-free AC power is nothing new. But the RI-1210 and RI-1220's unique technology and implementation are. Many competing designs that claim to reduce AC line noise rely on multiple-pole RFI filters; cheap, inadequate AC outlets; high-resistance thermal circuit breakers; or unrealistic performance from ferrite beads. [. . . ] Though the unit will function with a 15 Amp panel circuit breaker, it is not recommended, as vastly inferior performance and substandard protection (depending on your systems total current demands) could result. If your system includes power amplifiers or projectors with more than modest power demands, a panel circuit breaker with at least a rating of 20 Amps is essential for optimum performance. If other electrical loads are used on the same branch circuit, and your systems continuous current load is in well in excess of 10 Amps, we recommend a 30 Amp panel breaker wired with #10 gauge wire. For installations, which must comply with NEC codes, a 20 Amp panel circuit breaker with a dedicated line (branch circuit) is the minimum requirement. The RI-1210 will function well with standard household 15 Amp panel breakers and a 15 Amp branch circuit. If other electrical loads are used on the same branch circuit, they should be relatively modest, (well below 5 Amps total). If this is not the case, you will need to use a 20 Amp panel breaker and branch circuit. If in doubt consult your dealer or local electrician. The RI-1210 and RI-1220 are manufactured with four rubber feet for placement on any table, cabinet, shelf, or floor capable of supporting their weight. Because of the Reference Series' low-flux density transformer design, placement or proximity to other components is not critical, and the RI-1210 and RI-1220 do not produce any appreciable heat. Page 3 The Reference Series may also be rack mounted in a standard 19" rack by attaching the optional rack ears. These rack ears mount parallel to the back of the Reference Series' front panel. These optional rack ears come with the necessary hardware and mounting instructions. The RI-1210 requires a Furman HRKIT-7, while the RI-1220 requires a HRKIT-8. Due to the weight of the Reference Series' components, we recommend mounting these units at the bottom of your rack. Once the unit is placed, the detachable AC cord must be attached to the rear panel IEC male socket. When facing the rear of the unit, it is located in the lower left-hand corner of the rear panel. Next, the male NEMA-15 connector must be plugged into the appropriate AC socket. This AC cord will carry substantial unbalanced AC current, so it should be dressed away from critical signal carrying cables, or at the very least, crossed at a 90-degree angle. All three-prong AC cords exiting the RI-1210 or RI-1220 will radiate virtually no field at all, so their placement is not critical. The RI-1210 and RI-1220 feature additional filtering for digital components, or any component or processor with a switching power supply. These four outlets are clearly labeled on the rear panel of your Reference unit. The remaining six outlets are for analog components, (units without digital audio conversion, processing, or switching power supplies). [. . . ] The GFCI is located on the rear panel, and its AC outlets make up two of the six Analog AC outlets. Surge Protection The RI-1210 and RI-1220 are capable of suppressing virtually any instantaneous voltage surge caused by lightning or commercial power. However, the protection device may be damaged if the over-voltage surge or spike is sustained. The same is true if the device is made to absorb a direct lightning hit. [. . . ]
