QAS28 Yd(S)
The output terminal board is situated below the control and indica-
tor panel.
S2...... Emergency stop button
Push the button to stop the generator in case of an emergency.
When the button is pressed, it must be unlocked, by turning it
anti-clockwise, before the generator can be restarted. The
emergency stop button can be secured in the locked position
with the key, to avoid unauthorized use. Use this button only in
case of an emergency.
Q1 ..... Main circuit breaker and minimum voltage relay
Interrupts the power supply to X1 when a short-circuit occurs
at the load side, or when the earth leak detector (30 mA) or the
overcurrent protection (40 A) is activated or when the DC hold
coil is not energized. It must be reset manually after eliminat-
ing the problem and after each start.
X1...... Main power supply (400 V AC)
Terminals L1, L2, L3, N (= neutral) and PE (= earthing), hid-
den behind the control panel door and behind a small transpar-
ent door.
QAS28 YdS IT
The output terminal board is situated below the control and indica-
tor panel.
K4...... Insulation monitoring relay
Checks the insulation resistance and activates Q1 when the in-
sulation resistance is too low.
S2...... Emergency stop button
Push the button to stop the generator in case of an emergency.
When the button is pressed, it must be unlocked, by turning it
anti-clockwise, before the generator can be restarted. The
emergency stop button can be secured in the locked position
with the key, to avoid unauthorized use. Use this button only in
case of an emergency.
Q1 .....Circuit breaker for X1
Interrupts the power supply X1 when a short-circuit occurs at
the load side, or when the overcurrent protection (40 A) is ac-
tivated. When activated, Q1 interrupts the three phases towards
X1. It must be reset manually after eliminating the problem.
Q2 .....Circuit breaker for X2
Interrupts the power supply X2 when a short-circuit occurs at
the load side, or when the overcurrent protection (32 A) is ac-
tivated. When activated, Q2 interrupts the three phases towards
X2. It must be reset manually after eliminating the problem.
Q3 .....Circuit breaker for X3
Interrupts the power supply X3 when a short-circuit occurs at
the load side, or when the overcurrent protection (16 A) is ac-
tivated. When activated, Q3 interrupts the three phases towards
X3. It must be reset manually after eliminating the problem.
Q4 .....Circuit breaker for X4
Interrupts the power supply X4 when a short-circuit occurs at
the load side, or when the overcurrent protection (16 A) is ac-
tivated. When activated, Q4 interrupts phase L3 and the neutral
towards X4. It must be reset manually after eliminating the
problem.
X1...... 3-phase outlet socket (400 V AC)
Terminals L1, L2, L3, N (= neutral) and PE (= earthing), hid-
den behind the control panel door and behind a small transpar-
ent door.
X2...... 3-phase outlet socket (400 V AC)
Provides phases L1, L2, and L3, neutral and earthing.
X3...... 3-phase outlet socket (400 V AC)
Provides phases L1, L2, and L3, neutral and earthing.
X4...... 1-phase outlet socket (230 V AC)
Provides phase L3, neutral and earthing.
