X4 ....... 3-phase outlet socket
Provides phase L1, L2, L3, neutral and
earthing.
X5 ....... 3-phase outlet socket
Provides phase L1, L2, L3, neutral and
earthing.
X6 ....... 3-phase outlet socket
Provides phase L1, L2, L3, neutral and
earthing.
Dual voltage (2V)
The generator can run in two different modes:
3 phase, lower voltage
When using this selection, the generator provides a
230 V output voltage.
3 phase, higher voltage
When using this selection, the generator provides a
400 V output voltage.
Q1.1 ....Circuit breaker for low voltage, high
current
Interrupts the low voltage power supply
towards X1 when a short-circuit occurs at
the load side or when the overcurrent
protection (QAS 275: 690 A, QAS 325:
800 A) is activated. It must be reset
manually after eliminating the problem.
Q1.2 ....Circuit breaker for high voltage, low
current
Interrupts the high voltage power supply
towards X1 when a short-circuit occurs at
the load side or when the overcurrent
protection (QAS 275: 400 A, QAS 325:
470 A) is activated. It must be reset
manually after eliminating the problem.
R12......Voltage adjustment potentiometer
Allows to adjust the output voltage.
Circuit breaker Q1 does not only
interrupt the power supply towards
socket X1 but also towards X2, X3,
X4, X5 and X6.
Make sure to switch on circuit
breakers Q1, Q2, Q3, Q4, Q5 and Q6
after starting the generator when
power supply is done by means of
X2, X3, X4, X5 and X6.
