Connecting DC Power Cable To Unit
Line up the dc plug with the receptacle. Push forward while rotating the T-handle one full turn clockwise.
Ensure dc power cable plug is fully seated into the unit's DC Battery Receptacle. The unit is now ready to
safely transfer power.
Connecting DC Power Cable To Vehicle or Aircraft
Line up the NATO plug or Aviation dc plug pins and push it in. DC bus power should come on and aircraft
voltmeter should indicate 24 Vdc to 23.5 Vdc (23 Vdc minimum). Ensure DC power cable plug is fully seated
into the vehicle or aircraft's dc receptacle.

Low Power Demand
Low power demand is defined by a requirement of 50 amps or less. Connect dc power to vehicle or aircraft
ground power receptacle. DC bus power should come on and vehicle or aircraft voltmeter should indicate
28.5 Vdc to 27 Vdc (26.5 Vdc minimum). If vehicle or aircraft power demand is less than 50 amps converter
output will remain at 28.5 Vdc (only one GREEN LED status indicator bar will illuminate). If vehicle or
aircraft power demand exceeds 50 amps converter voltage output will decrease and two or more LED status
indicator bars will illuminate.
TI50A DC Power Supply
Unit is not rated for engine starting. It is to be used for ground maintenance
only.
Turn off DC Circuit Breakers before attaching cable to unit. Turn on DC Circuit
