Under What Conditions Do Inverters Need a NEBS Compliance Certificate?

Electrical equipment receives a NEBS compliance certificate when it meets the personnel and equipment safety requirements of GR-63-CORE and GR-1089-CORE (level 1); the operating requirements for a specific environment (level 2); or all the requirements for GR-63-CORE and GR-1089-CORE (level 3). Because the latter is designed to withstand the greatest number of adverse operating conditions, it is the most used type of NEBS equipment.

Adverse Operating Conditions

There are several types of adverse operating conditions that signal the need for equipment that has been tested and awarded the highest NEBS compliance certificate. If your company has an operating environment that includes any of the adverse operating conditions below, using inverters with the highest level of certification is essential for preventing them from failing during service.

Vibration

Vibration from engines, industrial machinery, blasting equipment, etc. could easily cause conventional equipment to malfunction. Level 3 inverters have a frame and components that are reinforced to withstand various types of vibration without experiencing failure during service.

Airborne Contaminants

Airborne contaminants are known to cause metal parts to oxidize and corrode, and may cause parts to be coated with a residue that sabotages the conduction of electricity. Level 3 equipment is designed to withstand a broad range of airborne contaminants without malfunctioning.

Humidity

High humidity is a common adverse operating condition in marine environments, industrial environments that contain a high amount of steam or vapor, and climates that have naturally high humidity. Level 3 equipment is designed to avoid humidity induced corrosion for years on end.

Extreme Temperatures

Level 3 inverters are perfect for operating environments that involve unusual temperatures, such as refrigerated areas, areas that are unusually warm due to industrial processes that generate heat, and areas where temperatures vacillate sharply due to exposure to the elements.

Natural Disasters

Disasters such as earthquakes, tornados, and hurricanes involve heavy vibration and/or increased humidity that can cause conventional hardware to malfunction. Level 3 equipment is designed to withstand these conditions and remain in operation despite natural catastrophes.

Conclusion

The adverse operating conditions above are just some of the conditions that require companies to use inverters that have a NEBS compliance certificate. If your company needs inverters, be sure to choose products that have been tested in the type of environment where they will be implemented.
