Primary Side Static Switch With Transformer & SafePanel Distribution
Basic Purpose
The Series 70 ePODs: Type-P provides switching between
two independent power sources on the primary side of the
transformer, while providing power distribution capabilities,
featuring a solid-state transfer switch on the primary side of the
transformer. The Series 70 ePODs: Type-P provides the ability
to transfer power between two or three sources in quarter of an
electrical cycle, while delivering that power to up to twelve subfeed circuit breakers.
This automatically or manually provides static transfers between
two AC sources in less than a quarter cycle, and safely transfers
this power downstream. The Series 70 ePODs: Type-P performs
open-transition transfer in such a manner that the connected load
disruption is minimized without ever cross-connecting the power
sources. A power source is specified as the preferred source, and
if the preferred source fails, the unit will automatically connect to
the alternative source until the preferred source is available again.
Power sources are not required to be synchronized with
our patented dynamic phase compensation technique. All
components of the machine are safely replaceable without the
need to de-energize the load.

Designed To Fit Into Your Data Center
Seamless Integration With Existing Systems
Far too often coordination with existing systems are afterthoughts. As a result, many data centers resort to makeshift solutions that
are inefficient and lacking in harmonization with existing monitoring software. LayerZero offers a wide choice of product options, all
designed to coordinate with your existing
power infrastructure. Our products
fully support open protocols, so that the
information generated from LayerZero
equipment seamlessly fits in to existing
monitoring packages. LayerZero supports
open connectivity utilizing open protocols.
Power distribution issues in the data center industry include:
Opportunity to Enhance Operator Safety
Need for Open Connectivity and Monitoring
Our Series 70 product line was developed to provide a
safe environment for the operator; and to assist critical
sites with staying in compliance with the stringent safety
requirements of NFPA 70E.
Coordinating information is difficult when clusters
of connected equipment are based on proprietary
protocols, and LayerZero solves this by basing the
equipment off of open technologies.
Lack of True System Redundancy
Lack of Comprehensive Diagnostics Tools
All of our equipment is truly redundant, so that if
individual components were to fail the systems will
remain fully operational. LayerZero equipment does not
contain any single points of failure.
To prevent future problems in facilities our systems
provide easy to read alarms with clear indications on
the sources of offending conditions, so that root-cause
analysis can be performed.

LayerZero Provides High-Reliability Power Distribution Solutions
Triple Modular Redundancy
The Series 70 ePODs: Type-P occupies a unique architectural location in mission critical infrastructure
systems, in that their tolerance for failure is virtually zero.
The units are available in SMR (Single Modular Redundancy) or TMR (Triple Modular Redundancy)
configurations, both of which are architectures that eliminate single points of failure.
The TMR configuration will continue its mission of being a static transfer switch even if any one control
element were to fail. As such, it is known to improve reliability by an order of magnitude.
Triple Modular Redundant products serve the needs of elite, mission-critical infrastructure
requirements. With our Triple Modular Redundant STS topology we can provide products that are at
least ten times more reliable than alternative solutions.
Serialized circuit boards
We serialize and track all critical circuit boards and memory cards through our eBOSS portal, which
allows customers to reference which components their machines are made from, who tested the
components, as well as the ability to view notes generated from testing.
Serialized components offer the ability to drill-down on prospective component failure utilizing
predictive modeling techniques, so if part fails, the instance can be cross-referenced with similar parts.
This preventative maintenance helps ensure maximum uptime.
Fail-safe mechanics
The bypass procedure employs a fail-safe measure to improve system reliability in that the procedure
can only be physically completed in the correct sequence.
A mechanical “double goalpost” interlock bar constrains the operators behavior so that breakers can
only be manipulated in an order maintain continuity of power to the load.
The restraint rotates downward for manual transfer testing purposes.
Waveform capture
Each transfer event and overload transfer-inhibit event is captured and stored in non-volatile memory.
The Waveform Capture tool is standard in all eSTS products. It provides 3-phase current and 3-phase
voltage waveform analysis of Source 1, Source 2, (Source 3 in a 3-source system) and Output
Precise voltage and current data is necessary to understand why a transfer was made. Detailed
records of transfers help operators better understand the root cause of events, helping engineers
properly eradicate problems. Without waveform capture, this is not possible in a live environment.
The 6-cycle capture is displayed on the control panel or can be viewed remotely on a standard webbrowser.

Providing An Array of Power Reliability Solutions
“Black box” forensic diagnostics
The black box capabilities of LayerZero equipment are extremely useful for analyzing root cause
analysis, enabling operators to pinpoint exactly where a fault occurred. “Black box” forensics provide
successive event information with ten microsecond resolution, supplies a brief snapshot of the event
with a lead-in for further inquiry, and furnishes a real-time status indicator of all machine parameters
at the time of the event.
The technology in our “black box” event history is one of the most useful recording schemes in the
mission critical power machine industry.
Voice guided bypass
To help prevent operators from completing the bypass procedure out-of-sequence, our products
feature a voice prompted bypass procedure. This instructs the operator in a step-by-step course of
action of the process, with only one operation per screen. Voice guided bypass slows down operators
and compels them to think about the process, significantly reducing the probability of operator error.
Visual and audio cues provide clear instructions on the bypassing sequence.
Epoxy coated buswork
Silver plated terminals
Our usage of epoxy coated buswork
helps ensure safety, protecting
operators from being exposed to live
parts.
LayerZero utilizes silver plating
on all of its machine components
to be able to provide the highest
performance. Silver has high
conductivity and low resistance which makes for a great contact.
Brazed invisible joints
Machined cap screws &
disc springs
Electrical copper bus joints
that cannot be accessed by the
operator for thermal scanning and
maintenance are brazed. This creates
a maintenance-free joint.
LayerZero systems are durable, sturdy,
and built to last.
© 2013 LayerZero Power Systems, Inc. Our systems utilize machined cap
screws and engineered disc springs
with a flat pressure vs deflection
profile to ensure that all bolted
connections maintain constant
torque through the life of the
product.

Designed To Provide Maximum Uptime
Optical fiber controls
Fanless operation
Fiber optic based controls eliminate
noise and interference, while isolating
components from high voltage.
Optical fiber allows service to be
reliably connected, while protecting
the equipment.
Fans and fan sensors are one of the
most common components to fail.
Staggered heat sink
The heat sink arrangement is
staggered between sources and
phases to minimize the creation of
extreme thermal gradients between
heat sink columns when conducting
on one source or the other.
For maximum uptime, Type-P
systems do not contain any fans,
filters, or fan fuses.

Best-In-Class Safety
InSight IR Portholes
Strategically positioned IR-scan portholes to enable safe thermal scanning of all bolted connections
with the deadfront closed, without exposing the operator to power circuit voltage.
The IR window swivels upward and unlocks with key-hole access to revel an arc-proof mesh, allowing
the operator to point-and-shoot thermal cameras to obtain accurate readings.
LayerZero provides extensive documentation and training for proper thermal scanning procedures.
Sectionalized Components
Normal operator sections (breakers/switches) are physically separated from the power electronics and
control electronics sections, so that maintenance on a section can be safely performed.
If maintenance is required on a particular section, power can be bypassed to another section to allow
for safe repairs to be made. All connections are optically isolated to minimize risk.
Insulated Parts
Operators are well-protected from exposed connections.
Energized parts are all insulated, covered, recessed, &/or internally mounted for safer operation of the
unit.
In addition, sections that isolate machine components are insulated.
Polycarbonate window to view diagnostic LEDs
Operators can view the status of diagnostic LEDs without direct exposure to the energized power
electronics section.
NFPA 70E
Our Series 70 product line was developed to exceed NFPA-70E regarding operator safety, to help data
centers drastically reduce the risks of their energy distribution systems.

The LayerZero SafePanel™
SafePanel distribution
The Series 70 ePODs: Type-P features an IP-20, finger-safe panel board, meaning that the opening will
not allow ingress of ½” (12.5mm) diameter probe, for maximum operator safety.
An arc can form as two live conductors are separated – such as the removal of a circuit breaker
from a panel board. The SafePanel design ensures that a potential arc would be contained in the
connection well so that even if a branch breaker were to be removed, the arc would be contained in
the connection well.
The CB can only be disengaged/removed when in the off position, which eliminates the possibility of
the creation of an arc or flash during breaker removal. When the CB is in the off position, access to
the mounting screw is locked out. When the CB is in the on positions, access to the mounting screw is
enabled via a sliding shutter.
Insulated with the components deeply isolated, removal of the breaker is safe and easy.
There is a convenience handle on the load side and a removable handle on the line side. The subfeed
circuit breaker is installed by placing the CB into the panel board and engaging the lock with a screw.

Intuitive Touch Screen GUI
Touch screen interface
The Dynamic Mimic Panel is presented on a 15” color touch screen Graphical User Interface, which
was carefully designed to be user-friendly, intuitive, and consistent.
A well creative and well organized “page” based navigation helps operators quickly get to the
information they need, without having to search around.
The GUI is “Read-Only” unless a user has logged on. A walk-up user may examine the state of
the switch, but can not change that state. This is “USER” level access. If a user has logged on by
providing a valid password, then he or she is allowed to view additional pages (Page-Level Security)
and to make changes to controls on pages (In-Page Security).
Access expires in 10 minutes. The 10 minute period is renewed if any Page navigation (ROOT or
PAGE) button is selected.
Operators have instant access to real-time power usage information, which is valuable for making
power-related decisions.
A mimic panel graphically show that current state of the switch and power flow, while health meters
provide operators with the capability to know the status of a TMR instantly.
Alarms are visible on every screen. Alarms clear themselves when the offending condition is fixed.
Until such time, Alarms persist. There is no “alarm clearing” button/capability. In a TMR system,
when an alarm is posted by only one SCB the system continues to operate as a fully functional STS.
Such an alarm points to a problem in only one of the three independent control systems.
Each transfer event and overload transfer-inhibit event is captured and stored as part of the history
of the machine. The transfer history can only be cleared by authenticated users.
