For Ground Power Supply able to provide multiple voltage, care must be taken
to always select 14V mode and check actual output voltage before connecting
the unit to the aircraft.
When selecting the current capacity of the power supply, always make sure to
comply with the requirement below. Connecting a power supply with a capacity
outside the required minimum or maximum Amps might result in voltage
tripping, overvoltage and damage to the battery.
Before connecting a Ground Power Supply, always make sure that:
• The male connector to be used is of type AN2551 3-pin
• The power source has a voltage of 14V
• Is protected for loads of max. 100 Amps (in any case)
• It is able to supply min. 75 Amps (if used for engine starting)
• It is able to supply min. 50 Amps (If used for charging the battery)
• It is able to supply min. 20 Amps (If used for powering the avionics)
• The source is connected with correct polarity
CAUTION
Failing to comply with any of the points above may permanently damage the
aircraft battery and electrical system!
