Connect the Graupner Polaron EX-1400 charger through the supplied cable to terminals on your
car battery with 12 or 24 V or alternatively to a suitable power supply with an output voltage of 12
... 28 V DC stabilized power and output power of at least 25 A.
The optional polaron PSU, Order Nr. S2012 has to be docked to the left side.
Remove the unit stand from the charger by rst pushing it forward gently and then remove it from
the bottom of the charger. Drag afterwards the unit base apart and, after connecting the power
supply plugs, insert it under both devices.
The power source and the charger will be connected through the black wire to the nega-
tive terminals (-) and the red to the positive (+)! The charger is indeed equipped with re-
verse polarity protection, so that incorrect insertion does not generate an immediate de-
struction of equipment. However, it cannot be started. Disconnect the power cable and then insert
it again with the correct polarity.
INSTRUCTIONS
