MODEL: XL-3D 480
PARTS REQUIRED:
Parts to be supplied by the installer. Similar parts may be
substituted. Additional parts may be required depending
upon installation configuration.
1. Circuit breaker: 70 amp 3 pole (SWD rated)
2. PVC pipe (size/ quantity as required)
3. PVC T/A (size/ quantity as required)
4. PVC LB (size/ quantity as required)
5. Wire: use #4 THHN single conductor
6. When not installing the 70 amp breaker into existing
panels, use a disconnect rated for 100 amps or
larger and still fuse for 70 amps
CAUTION: DEENERGIZE ALL ELECTRICAL POWER TO THE PANEL AND EQUIPMENT BEFORE
COMMENCING INSTALLATION.
CAUTION: The point at which the USES® unit is connected to the electrical system must be on the line side of any
controller for any motor or load.
CAUTION: Confirm all phase-to-phase and all phase-to-neutral voltages match those listed in Table 1 for the model
being installed before commencing installation.
CAUTION: USES® unit must be installed by a licensed electrician. Installer is responsible to ensure all aspects of
installation comply with the NEC and local electrical codes. All foreign country installations must comply with
their electrical codes.
CAUTION: USES® unit must be installed on the line side of a variable speed drives, magnetic motor
controllers and frequency control drives. If put on the load side equipment damage may occur
INSTALLATION:
1. Install the circuit breaker in the electrical panel. "
2. Mount the USES® unit. The total wiring length from unit to
the circuit breaker must be 10' or less.
3. Run conductors and the neutral wire (if present) into the panel.
4. Connect neutral wire (if present) to neutral bar in the panel
5. Connect conductor wires to the circuit breaker.
6. When not installing a 70 amp breaker into existing panels, use
disconnect rated for 100 amps or larger and still fuse for 70 amps.
OPERATIONAL CHECKS:
1. When ready to energize the USES® unit, shut the circuit breaker
2. Observe the lights on the side of the USES® unit. All should be lit and equally bright. If not, deenergize the
USES® unit, verify the wiring is correct ant that proper phase-to-phase and phase-to-neutral voltages exist.
Contact your USES® dealer if the voltage is correct but the lights were not lit or equally bright.
3. Confirm that the current on the conductors from the USES® unit to the circuit breaker as listed in
Table 1 (± 20%) for the model being installed.
4. Periodically verify the indicator lights are lit and equally bright. Contact your USES® dealer if they are not. * If
the breaker space is not available in an electrical panel or if the USES® unit is being installed local to a load a
circuit breaker disconnect may be used provided it meets NEC requirements. The point at which the USES®
unit is connected to the electrical system must be on the line side of any controller for any motor or load.

Magnetic phase balancing of
voltage and current to safely
reduce waste, demand, friction
and heat in loads;
Passive resonance-free power
factor correction to reduce the
demand of reactive non-power
currents;
Harmonic filtering of non-power
currents to reduce the billed kWh
consumption and improve power
quality;
Transient energy conversion through
the surge protections self-healing
magnetic chokes – energy above the
operational voltage is absorbed, re-
constituted, and returned to the
customer as usable safe power;
Power generation via the USES®
proprietary chokes: voltage and current
are generated from each phase and
injected into the adjacent phases as
usable power, reducing kW demand and
kWh consumption.
How USES® Works – 5 Methods
The patented USES® technology is a dynamic, passive, resonance-free magnetic field
induction system that reduces kW demand and kWh consumption through five methods:

Results Granite Asphalt Plant
 Real Power Demand Average (kW) – Real Power demand was reduced by an average
18.88 kW (4.13%) at low load operational levels with 9 USES Power Conditioners
activated. Each USES unit was individually tested and found to be operational and
contributing to the overall power quality improvements as presented in the Power Shaver
proposal of April 2012. During the Off-Peak TIS testing of August 15, 2012, the average
real power demand reduction was 18,884.71 watts. The results are used in the ROI and
Savings calculations because they are representative of low circuit load conditions.
 Real Power Demand Instant (kW) – Real Power demand was reduced instantly by 23.45
kW (5.14%) at low load operational levels with 9 USES Power Conditioners activated.
 Apparent Power Average – Apparent power was reduced from 588.014 KVA to 483.814
KVA when the USES System was activated. The average apparent power reduction was
104.230 KVA (17.73%).

Results Granite Asphalt Plant Continued
 Apparent Power Instant – The instant Apparent Power reduction was 113.571 kVA
(19.31%) at low load operational levels with 9 USES Power Conditioners activated.
 Reactive Power – Under low load, the Reactive Power was reduced from 370.045 KVAR to
193.863 KVAR when the USES System was activated. The average reactive power
reduction was 176.566 KVAR (47.7%).
 Power Factor – Under low load, the Power Factor improved from 78% to 92% (18%) and
remained lagging when the USES System was activated.
 Amperage – Under low load, the circuit Amperage was reduced by 135.53 amps (19.2%) on
each phase when the USES System was activated.
 Voltage – Voltage improved by an average of 4.73 volts (.985%) per phase (VAB, VBC, VCA)
when the USES System was activated.

 Isola, CA: Per ISOLA’s corporate energy reduction desires, the USES® XL
model line was installed to reduce energy consumption and electrical costs of
operation and to solve a spiking and sagging voltage condition from the utility
district’s local distribution system that has been interrupting and shutting down
Isola’s 24/7 manufacturing on a regular basis. Our Isola engineers have been very
impressed with the Power Shaver system to accomplish our goals. Very surprising
to our engineering and accounting staff tasked with evaluating the energy reduction
and cost-savings ability of the USES® system, was the additional 27% reduction in
electrical cost that we verified. This savings is in addition to the Power Shaver
guaranteed $50,000 per year and 18-month payback. Isola’s actual payback period
for our USES® system is 13 months. Isola Group has determined the USES® XL
system to be a valuable asset to our company and will continue to recommend it to
our industry associates.

 Island Colony HI: The AOAO ISLAND COLONY is a 740-room condominium/ hotel and is the tallest building
in Waikiki, Honolulu, Hawaii. For many years, we have experienced very poor power quality from our utility, including
frequent brownouts and outages. The result of these conditions has been damaging to our equipment — such as
burned-out elevator control boards, destroyed closed circuit surveillance systems and cameras, along with a very
high rate of LED driver failures. We installed the Power Shaver USES® efficiency and conditioning system to
improve power quality and protect our facility from damage. I am happy to share that the USES® system has
eliminated the elevator and CCTV power quality-related interruptions and damage and significantly reduced the LED
driver failure rate. In addition to these benefits, the adjusted energy and cost reductions provided by the USES®
system are at approximately 10%, exceeding the pre-installation projections. The USES® system is on track to pay
for itself in less than one year.
