power supplies such as those found in power amplifiers, the current readings actually come down. This is due to

what's known as a vector load, and it's quite dynamic in an audio/video system. In this scenario, there is one thing

that can run somewhat warmer than it might otherwise: the AC cord that supplies power to the Niagara 7000EU.

This is because the wiring and the circuit breaker that supply power to Niagara 7000EU simply look at RMS current

and do not distinguish between reactive loads, resistive loads, or inductive loads, but your utility does.

This circuit and many like it have been utilized for many years, and, when tested into buildings with absolutely

no loads present aside from the transient power correction circuit, there was virtually zero power draw from the

utilities' power meter. Still, in an age where so-called "smart meters" are omnipresent, and some utilities may or

may not change their standards for "what type of power or current is suitable for billing," we have gone to great

lengths to offer an alternative to those who may be concerned, but who nevertheless wish to achieve the best

possible audio/video performance.

Again, if you wish to utilize this feature, and your amplifier(s) and/or powered receiver meet the criteria, simply

place the Power Correction Switch in the "Standby" position. Otherwise, please leave the switch in the "Engaged"

position.

Ground Fault Circuit Interrupter (GFCI) "Test" Button/Momentary Switch

To offer unparalleled safety and security for both you and your valuable equipment, the Niagara 7000EU

features a ground fault interruption circuit for the Ultra-Linear Noise-Dissipation Dielectric-Biased Symmetrical

Power outlets. This will trip the front-panel power switch (which also acts as an ultra-low resistance 16-amp RMS

magnetic circuit breaker) if there is ever more than 5.5mA of current leakage from Line to Ground or Neutral

to Ground. This is extremely rare, and only exists as these two outlet banks (outlets 5 through 12) utilize two

isolation transformers as part of their circuitry. Since the output is Symmetrical (Balanced), there is voltage

potential on Neutral relative to Ground. In and of itself, this is not at all a problem or danger; in fact, it is precisely

the feature used by the transformer in most components with a linear power supply (in that application, called

"center tapped").

However, if a connected component's power supply were to suffer a catastrophic failure, there would be a

remote possibility of some AC voltage being present on the component chassis. With the incorporation of the

GFCI, this is not possible, as the current fault would shut off the main power switch within a fraction of a second.

Because we insisted on creating it for optimal performance and safety, this method of redundancy protection is

complex and costly. As a result, the symmetrical outlet banks in the Niagara 7000EU are safer to use than those

found in any home, office, or hospital.

To ensure the circuit is functioning properly, simply lightly press the button. (It is a momentary switch, so it will

not latch.) This should instantly disengage the front panel's power switch/circuit breaker, and the blue power

indicator will no longer light. Once this "test" has been performed, you will not need to do so again unless the

unit is moved or has been serviced.

Extreme Voltage Indicator

One portion of the Niagara 7000EU's non-sacrificial surge protection is dedicated to a fast-acting extreme

voltage shutdown circuit. If more than 275VAC is present on the incoming AC line for more than a quarter of

a second, the circuit will instantly open a high-current relay that will disengage the AC power from all of the

Niagara 7000EU's AC outlets, activating the red front-panel LED "Extreme Voltage" warning indicator. Once the

event has passed, or the building wiring fault has been corrected, the circuit will automatically re-engage.
