Access Safety Features
LayerZero Power Systems is committed to operator safety at every level of access. From visual inspections to full system maintenance, our equipment is engineered to minimize risk, eliminate exposure to live parts, and support fast, efficient workflows in mission-critical environments. This page highlights how our dead-front hinged doors, internal insulation, and front-only design philosophy work together to provide unmatched access safety.
Dead Front Hinged Doors
All LayerZero equipment features dual-layer dead-front hinged doors that separate operators from internal energized components. These doors are engineered to remain closed during normal operation and allow access to key visual indicators and ports without opening the inner chamber.
- Operate circuit breakers without exposing live wiring
- View onboard LED indicators with all doors closed
- Perform IR thermal scans through InSight IR® Portholes
No Exposed Live Parts
Operator protection starts with removing the risk of accidental contact. That’s why LayerZero designs every system with covered, recessed, or internally mounted energized components. All input terminals and buswork are either shielded or enclosed, and critical areas are further protected by polycarbonate inspection windows.
In many cases, inspections, diagnostics, and maintenance can be performed without ever exposing the operator to electrical energy. This design aligns with NFPA-70E best practices and provides peace of mind during every interaction.
- Insulated and recessed conductors
- Inspection windows for visual and IR diagnostics
- Optional breaker shrouds for ePanel and SafePanel configurations
Front-Only Access
The majority of LayerZero equipment is designed for full front-only access — meaning all serviceable areas, cable connections, viewing ports, and thermal access points are located at the front of the system. This greatly reduces the risks associated with navigating around energized cabinets and improves accessibility in space-constrained installations.
- Safe: No rear or side access required during normal operation
- Efficient: Enables faster inspections and simplified service workflows
- Compact: Ideal for high-density layouts and modular deployments
Some high-current systems (such as the 4000 A eSTS) may still require rear access for specific IR scanning tasks — but even in these cases, LayerZero applies safety-first engineering to reduce exposure and simplify access.
