Unitron 400 Hz GPU, Frequency Converters and PCA Systems * Safety Alert

PRODUCTS | AIRCRAFT GROUND SUPPORT EQUIPMENT | 28 VDC POWER | SAFETY ALERT

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” is the only mobile DC power cart on the market that 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*
