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 developed to exceed the recommendations of NFPA-70E and to help data centers drastically reduce the risks of exposure to electrical energy.

InSight™ IR Portholes are openings in LayerZero units with hinged covers for ease of thermal scanning of all bolted connections. Thermal scanning bolted connections is a common procedure for preventive maintenance.
The covers of InSight™ IR Portholes swivel outward to reveal a mesh. The mesh helps protect operators, while ensuring full functionality of thermal scanning ability. The usage of InSight™ IR Portholes makes it safer for operators to measure bolted connections.

All LayerZero systems are designed to be installed from the front only. These designs are safer and easier to maintain than installations that require back or side access for normal operations. They also take up less space. Advantages of front-only access include:
• Safe Design

Isolated Components To Minimize Risk
Normal interface sections (breakers/switches) are physically separated from the power electronics sections and control electronics sections so that maintenance on a section can be safely performed.
If maintenance is required on the electronics section, power is bypassed to allow for safe repairs to be made. All connections are optically isolated to minimize risk.

Protection From Exposed Connections
LayerZero Power Systems products are NFPA-70E inspired and are designed for safety, operators are well-protected from exposed connections.
Energized parts are insulated, covered, recessed, or internally mounted for safe operation of the unit. Sections that isolate electric and electronic components are insulated.

The bypass procedure employs a unique fail-safe measure to improve operator safety. The procedure itself can only be completed in a correct sequence.
A mechanical "double goalpost" constrains the operator's behavior so that breakers can only be moved in a sequence that will protect the operator from error and maintain the load.

Providing Visibility and Protection
All doors are equipped with door-switches so that an alarm is recorded when the door is opened. Polycarbonate windows allow operators to safely view the status of internal LEDs located on printed circuit boards.
Polycarbonate shields provide effective protection against exposed live parts.
