Suggested AC Connection
Soft Start - Continuous Use and Break-In Time
When power is rst applied to the IT-Reference 15i, (the front panel breaker- power toggle must be switched to the “on”
position) the Soft Start feature is activated. There is an audible “clack” when the IT-Reference 15i is rst turned on or o.
This sound is produced by the Soft Start circuit’s 30 Amp relay engaging or disengaging. There is virtually nothing in the
IT-Reference 15i’s construction, design, or componentry to wear over the life time of the product, and there is no power draw
from your electric service meter aside from the LED power indicator, relay, and GFCI protection circuit. For this reason the
IT-Reference 15i may be left with its power engaged permanently at a cost of pennies per month. This is an added benet,
as many audio/videophiles nd performance improves signicantly when leaving low-powered components permanently
charged (turned on). In fact, this is true of the IT-Reference 15i. Though it will function awlessly right from its shipping
carton, the performance of its circuit parts will improve after approximately two weeks of continuous use or “break-in.”
Ground Fault Interrupter (GFCI)
The IT-Reference 15i’s “Discrete Symmetrical Filtered AC outlets” incorporate a balanced AC power output, whereby both the
neutral and positive leads of the AC cable run at 60 Volts AC in opposing polarity, referenced to ground (0 Volts AC). This is
but one of the IT-Reference 15i’s advantages over other AC-lter/protection designs.
Though virtually all domestically produced electronic equipment is designed to detect electrical shorts and other potentially
dangerous equipment problems in the Line lead referenced to its Neutral, this is inadequate when power is symmetrical or
“balanced.” With the IT-Reference 15i’s symmetrical outlets, both neutral and positive legs contain 60 VAC relative to their
Ground tab. This is not a problem or safety hazard, unless there is a defect in either the IT-Reference 15i’s transformer, or the
power supply of a connected component. In this instance, we need to assure that safety is always maintained. The solution is
our GFCI (ground fault circuit interrupter).
The Furman GFCI detects any imbalance in the current owing in the two hot legs. The missing current is presumed to be
owing through the ground conductor (the round pin on an AC outlet). Ground current often indicates a dangerous partial
or full short circuit. If an imbalance is detected, the GFCI will trip the outlets internal breaker, and the Duplex AC outlet will
no longer supply AC power of any sort. To restore operation, correct the fault, press the reset tab located between the two
balanced AC outlets. 5 mA of current is enough to cause the GFCI to trip; to troubleshoot this type of problem, start with
nothing connected to the IT-Reference 15i’s balanced power outlets. Then, add each piece of equipment until the GFCI trips.
