N20
110 V to 120 V DC capacitor tripping device
(SINAMICS GM150 in the IGBT version)
The capacitor tripping device is used if the existing circuit
breaker has no undervoltage coil and cannot be retrofitted
with one.
It is installed in the converter and has the following functions:
•
Monitoring of the auxiliary voltage supply of the circuit breaker
on the plant side
•
Monitoring of the own internal voltage supply
•
Locking of the circuit breaker in the open position if there is
insufficient voltage
The capacitor tripping device ensures that the circuit breaker on
the plant side can still be safely opened even if there is a power
failure or the normal OPEN command is not effective, e.g.
because of wire breakage.
N21
230 V DC capacitor tripping device
(SINAMICS GM150 in the IGBT version)
The capacitor tripping device is used if the existing circuit
breaker has no undervoltage coil and cannot be retrofitted
with one.
It is installed in the converter and has the following functions:
•
Monitoring of the auxiliary voltage supply of the circuit breaker
on the plant side
•
Monitoring of the own internal voltage supply
•
Locking of the circuit breaker in the open position if there is
insufficient voltage
The capacitor tripping device ensures that the circuit breaker on
the plant side can still be safely tripped even if there is a power
failure or the normal OFF command is not effective, e.g. because
of a wire break.
N22
Switch on the input side
(static excitation unit, see Accessories, Chapter 7)
When option
N22
is chosen, a circuit breaker which is controlled
by the static excitation unit itself is integrated on the input side.
On the variants for brushless reverse field excitation this circuit
breaker is configured as a contactor, on the variants for slipring
excitation as a disconnector.
Note:
If this circuit breaker is not available, an external circuit breaker
must be provided.
N30 to N33
Controlled motor feeder for auxiliaries
400 V 3 AC/480 V 3 AC
An outgoing feeder for the operation of external auxiliary equip-
ment, e.g. separate fans on the motor or pumps/oil supplies, is
available in the converter. It is controlled and is fused by motor
circuit breakers. The voltage supply required for the drive must
be provided from an external source.
Depending on the drive output that is required, four different
outgoing feeders are available.
The contactor is closed with the
ON
command at the converter
and opened with the
OFF
command.
Note:
Other voltages are also possible according to the ratings in
question.
Note:
It is not possible to combine several options (
N30 to N33
).
