Series 70 eRPP
Basic Purpose
The LayerZero Series 70 eRPP provides a convenient means to
distribute power in a selective trip coordinated; and safe manner.
Inspired by NFPA-70E, the Series 70 eRPP™ remote power panel
is ideally suited for today’s high density always-on data-processing
environments.
The Series 70 eRPP increases reliability in two ways:
• Utilizes Finger-Safe Panel Board
• Provides Selective Trip Coordination Up to 25kAIC
With its SafePanel™ advanced design, there are no live parts
exposed when the deadfront is open and you can add a branch
breaker safely. Selective tripping eliminates the catastrophic
problems associated with the tripping of the panel board
main breaker in the event of a fault in the distribution system
downstream of a panel board branch breaker.
The panel board of the eRPP is designed for maximum operator
safety with its fully enclosed molded plastic bus and non-
conducting screws. Perfect for a raised-floor application, all feeder
and branch connections can be installed & thermal scanned fully
front and top of the Series 70 eRPP.

Series 70 eRPP
The Difference Is In The Details
The Series 70 eRPP provides power distribution with a focus on safety, reliability, connectivity, and information centricity. The
eRPP is on the forefront of design ingenuity, designed to meet the needs of professionals with the highest standards, providing
safe, selective-trip coordinated power that is flexible, scalable, and extremely reliable. The Series 70 eRPP empowers data center
specialists with a wealth of remotely-accessible power information, compatible with standard system management software.

LayerZero Designs For Long-Term Performance
The Series 70 eRPP is constructed to be strong and exceptionally reliable, both electrically
and mechanically.
Designed for safe and easy maintenance, the shape of the SafePanel™ on the eRPP
significantly reduces the probability of operator error, helping to ensure maximum uptime.
Operators are less prone to make mistakes when working with a finger-safe panel. Design
details such as breaker bolts that are not live and insulated buswork also help increase
reliability by putting less stress on operators.
Each branch breaker undergoes one controlled thermal trip and two controlled
instantaneous trips to ensure that the branch breaker performance is within design
tolerance.
Maximize Reliability With Selective Trip Coordination
The trend toward higher power density designs in modern data centers has created new difficulties in establishing proper circuit
breaker coordination. Higher capacity power distribution transformers with lower per-unit impedance has elevated fault current
levels and placed increasing coordination pressure on all downstream protective devices.
Main circuit breakers in series with traditional zero crossing branch circuit breakers may not permit proper selective trip coordination
at elevated fault current levels.
Selective trip operation via proper coordination is achievable at very high prospective fault current levels by using current limiting
(fast acting) branch circuit breakers.
Current limiting branch circuit breakers substantially ease the coordination design process, improve overall system reliability and
yield measurable uptime improvement for the mission critical facility end user.

Branch Breakers Need To Be High Speed Because:
Push Close
Contact Closes
Current Flow (Load) Current Flow (Source)
True mission critical performance is achieved when RPP
components are designed to trip selectively; AND have the property of current-limiting or
high-speed tripping.
Fast Acting Circuit Breakers
The circuit breakers in the Series 70: eRPP are plug-in, high-speed, current limiting, 25kAIC; designed for selective tripping. A bolted
fault on the output of one branch circuit breaker is interrupted in less than 4 milliseconds. This fast tripping action, combined with
the fact that the main circuit breaker does not trip means that the rest of the loads fed by the panel board survive the fault.
The voltage interruption on the main bus is less than a quarter cycle.
The panel board designed with fault withstand rating of 25kA for robust performance in a dynamic environment.
- This means that the panel board main bus experiences an outage that loads cannot tolerate
before the fault is cleared.
- In this situation, even if selective tripping is ensured by the proper selection of the much slower
main breaker, all of the panel board loads may be lost by virtue of a longer outage on its main bus.
• Computer loads cannot
withstand an outage greater
than 20 milliseconds (roughly
1.25 electrical cycles), per ITIC.
• When a fault occurs downstream of
a branch breaker, it impinges zero-
voltage on the main bus of the panel
board until the breaker is able to trip
open and clear the fault.
• A conventional “zero-crossing”
type branch breaker can take
several cycles to trip open when
subjected to a downstream fault.

Reliability
Screw Thread Inserts
LayerZero utilizes Heli-Coil inserts on bolted joints for prevailing torques and long-term reliability. Such connections are designed to retain a constant torque throughout the life of the product.
Convection Cooling
For maximum availability, the Series 70 eRPP utilizes convection cooling. The convection cooled eRPP design allows for heat to be safely dissipated without the need for fans, for higher reliability.
Machined Cap Screws & Disc Springs
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 for operator safetyAn 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 even if a branch breaker were to be removed.
The connection well is over 1” deep
Designed For Raised Floor Application
The unit is raised to provide for space for cabling at the bottom of the unit, and the holes punch downward to allow for easy cable installation.
Polycarbonate Window
The status of breakers can be safely viewed through the window.
Safety in the data center is a serious concern, as the hazards associated with arc flash and electrical shock kill, blind, and burn thousands of workers annually. Most of the damage caused by workplace accidents can be prevented.
We believe it is the responsibility of manufacturers to proactively design equipment that does not require exposure to energized parts during normal operations.
Our Series 70 product line was inspired by NFPA-70E to help critical facilities drastically reduce the risks of exposure to electrical energy.

LayerZero systems easily connect to a standard web browser over a VPN so that the information can be securely accessed remotely.
The eRPP generates a wide variety of power usage information, which can help managers better identify potential problems, assess the power usage to drive business decisions, and develop a basis for determining what can be done to improve the process.
Without measurable information, a greening or reliability strategy is difficult to follow through. The Series 70 eRPP provides the right information in a timely manner to help operators and managers make sound, well thought-out decisions.
