Product Brochure Series 70: eSTS 150 A - 1200 A Static Transfer Switch eSTS Static Transfer Switch Purpose The LayerZero eSTS Static Transfer Switch Maximizes Power Reliability eSTS Transfers Between Multiple Power Sources The Series 70 eSTS is a solid-state transfer switch that automatically or manually provides static transfers between two three-phase AC sources in less than a quarter cycle. The eSTS performs open-transition transfer in such a manner that the connected load disruption is minimized without ever crossconnecting the power sources. One power source is selected to be the preferred source. If the preferred source fails the load is automatically and seamlessly connected to the alternate source by means of an open-transition static transfer. 2 Series 70: eSTS Brochure © 2014 LayerZero Power Systems, Inc. eSTS Product Overview Section Contains: Power electronics • SCRs (Silicon Control Rectifier) • Snubber Circuits Heat-sinks Control Electronics • System Control & Data Boards • SCR Gate Drives • Redundant Power Supply System • I/O system; VPN Router Section Contains: Input isolation switches Bypass isolation Switches Output isolation switches Source connection terminals Load connection terminals Product Features Reliability Safety Power Quality Monitoring Safe Bypass Procedure InSight™ IR Portholes Waveform Capture Voice Guided Bypass Sectionalized Components “Black Box” Forensic Diagnostics Optional Triple Modular Redundancy Polycarbonate Windows Touch Screen Interface Epoxy Coated Buswork Front-Only Access Waveforms Automatically Emailed Silver Plated Terminals Dead-Front Hinged Doors Maintenance-Free Joints Machined Hardware Connectivity Screw Thread Inserts Ethernet Connectivity Convection Cooling Modbus/TCP Optical Fiber Based Controls NTP Time Clock Synchronization Serialized Critical Board Tracking SNMP Connectivity 3 Series 70: eSTS Brochure Agency Certification The Series 70 eSTS is ETL listed to UL 1008 Certified To CSA Std C22.2 No. 107.1 © 2014 LayerZero Power Systems, Inc.

Safe Bypass Procedure Mechanically Interlocked for Sequenced Operation In order to minimize the possibility of operator error during equipment bypass operations, LayerZero provides: 1) Interlocked breakers 2) Mechanisms to ensure that a source cannot be bypassed without the STS on the correct source. 3) Safeguards to make certain that sources cannot be connected to each other inadvertently. 4) A voice-prompted bypass procedure that guides the operator through the sequence. 5) A step-wise pictorial & video presentation is provided on the touch-screen display during bypass. 6 Series 70: eSTS Brochure © 2014 LayerZero Power Systems, Inc. Voice Guided Bypass Designed To Eliminate Human Error The number one cause of static switch load-loss is operator error during maintenance 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.

Triple Modular Redundancy Option The Ultimate In Power Reliability Three Logic Paths instead of One • Three Data Acquisition Boards • Three System Control Boards • Three drives per phase (i.e. per SCR pair) • 1-2 orders of magnitude more reliable than a single path. The Series 70: eSTS occupies a unique architectural location in mission critical infrastructure systems. 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. TMR Control Boards 8 Series 70: eSTS Brochure © 2014 LayerZero Power Systems, Inc. Epoxy Coated Buswork Helps Ensure System Reliability Our usage of epoxy coated buswork helps ensure safety, protecting operators from being exposed to live parts, and making the system inherently more reliable by eliminating the possibility of bus-to-bus faults.

Sectionalized Components Sectionalized Components Help Maximize Operator Safety Operators are well-protected from exposed connections. 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. 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. Control Section Isolated from Circuit Breakers 16 Series 70: eSTS Brochure © 2014 LayerZero Power Systems, Inc. Polycarbonate Windows View Status LEDs With Dead-Front Doors Closed Our Series 70 product line was inspired by NFPA-70E, to help data centers drastically reduce the risks of their energy distribution systems. Operators can view the status of diagnostic LEDs without exposure to the energized power electronics section. LEDs on Critical Board 17 Series 70: eSTS Brochure © 2014 LayerZero Power Systems, Inc. Front-Only Access Front Only Access Enhances Critical Load Reliability The Series 70: A eSTS can be installed, operated, diagnosed and maintained from the front. The dead-front panels are hinged, and side or rear covers never have to be removed. Thermal scans of every single bolted joint in the product can be done from the front of the system – without ever having to open the dead-front door. Unhinged covers can be bulky and unwieldy, and operator error during removal and replacement of covers has been known to cause mishaps and compromise load reliability. A safe, non-invasive operation and maintenance regime results in a higher reliability of the critical load. 18 Series 70: eSTS Brochure © 2014 LayerZero Power Systems, Inc.

Waveform Capture Real-Time Waveform Capture Each transfer event and overload transfer-inhibit event is captured and stored in non-volatile memory. 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 3 cycles before and 3 cycles after the transfer event. 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. Waveform Capture on Local Display The 6-cycle capture is displayed on the control panel or can be viewed remotely on a standard web-browser. LayerZero Waveform Capture Can Help You: • Fingerprint Incidents • Find The Root Cause Of Events • Monitor Power Quality In Real-Time • Waveform Capture On All Devices 21 Series 70: eSTS Brochure © 2014 LayerZero Power Systems, Inc. “Black Box” Forensic Diagnostics “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. System Control Board “Black box” event history is one of the most useful recording schemes in the mission critical power machine industry. LayerZero Black Box Forensics Can Help You: • Reconstruct The Sequence of Events • Find the Root Cause of Power Quality Incidents • Record Snapshots of the Power 22 Series 70: eSTS Brochure © 2014 LayerZero Power Systems, Inc. Touch Screen Interface 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. 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. Operators have instant access to real-time power usage information, including realtime waveform capture. A mimic panel graphically shows the current state of the switch and power flow, while health meters provide operators with the capability to know the status of a TMR instantly. The presence of an alarm is visible on every screen. Active alarms can be silenced. 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. 23 Series 70: eSTS Brochure © 2014 LayerZero Power Systems, Inc.
