(208 or 220V). They cannot be plugged together; it could cause a short
circuit. To plug in one cable the other must be removed and isolated.
The three cables must have the same voltage (208V USA or 220V Bra-
zil).
Power : 56 kVA at peak;
Maximum output current: 2,000 A;
5 seconds off peak with voltage drop of 20%.

SWITCH FOR ADJUSTMENT OF THE OUTPUT TENSION
(PN 28.01.1150)
It sets the output tension from 24 to 33VDC.

SWITCH FOR ADJUSTMENT OF THE OUTPUT CURRENT
LIMITER (PN 28.01.1122)
Placed on the right side of the panel, it must be used to set the maximum
current allowed on the aircraft in which it is connected. The accuracy
of this setting is around 5%.
The current limit is taken by a complete disconnection of the output
current after 1 second exceeding the set value.
Never place the current limiter knob in range below that demanded by
the load necessary for maintenance or during starts to avoid cuts during
the maintenance or at the start. Please check the aircraft manual to know
about its maximum current demanded.
ATTENTION:
The setting above the maximum current range allowed by the aircraft
does not mean that the current will come to this value in normal condi-
tions, even at the start.
Under normal conditions the GPU will deliver only the current de-
manded by the aircraft.
