Unitron’s “Safety GPU” meets the 18-inch requirement of the NEC fire and safety standards

Many companies are unknowingly in violation of the NFPA's National Electrical Code® regulations for 28 VDC mobile ground power units (GPUs) used in hangar operations.

Article 513-11(a) of the National Electrical Code (NEC®) states that it is hazardous and in violation of National Fire Protection Association (NFPA) regulations to operate elec- trical power sources to energize aircraft inside a hangar, unless all electric equipment and fixed wiring are mounted at least 18 inches from the ground.

Unitron’s “Safety GPU” meets the 18-inch requirement of the NEC fire and safety standards.

Using a GPU that meets the NEC standards:

	Eliminates potential fire and personnel safety issues in your hangar operation.
	Eliminates the risk of unpaid insurance claims due to non-conformance to standards code.

Additional safety features of Unitron's 28 VDC PwrKart™ include:

	*Advanced Safety Interlock System* - eliminates arching and removes voltage from plug head when unintentionally detached from aircraft. Prevents the danger of a live plug on the hangar floor.
	*Emergency Mushroom "OFF" Switch*
