Options
(continued)
G21
Communication Board CBE20 right
With option G21, an Advanced CUD can be inserted in the right-
hand slot (refer to option G11), which is used to expand CBE20.
More detailed information on the functionality, selection and
ordering data of the CBE20 is provided under option G20.
G63
Terminal Module Cabinet (TMC)
The Terminal Module Cabinet (TMC) is equipped with spring
terminals which provide a simple means of connecting CUD
standard signals.
This is made possible by routing the appropriate interfaces
(X177 of the CUD) to the TMC using an adapter board and a
ribbon cable (X71, X72).
The TMC comprises two terminal blocks and a cable set.
Note: To equip two CUDs with one TMC each, option G63 must
be ordered twice.
L04
Armature circuit supply with extra-low voltage 10 to 50 V
With option L04, the SINAMICS DC MASTER is re-equipped
for operation with 10 to 50 V AC. This is frequently required
especially for electrochemical applications, when controlling
solenoids, when using the converter to supply the fields of
special motors or Ward-Leonard converters (MG sets).
This option can only be selected for units with rated supply
voltages of up to 575 V.
L05
Electronics power supply for connection to 24 V DC
With option L05, users have the possibility of equipping
SINAMICS DC MASTER with an electronics power supply for
connection to 24 V DC instead of the standard electronics power
supply. This option allows users to connect the units to a
favorably-priced 24 V UPS system.
This option cannot be selected for Control Modules as the
Control Module is supplied as standard with an electronics
power supply for connection to 24 V DC.
Input voltage range: 18 to 30 V,
current consumption: 5 A at 24 V
L10
Without field power section
In some applications it may be necessary to individually adapt
the field power section. For this particular case, users can order
option L10 where SINAMICS DC MASTER is not equipped with
the standard integrated field power section. This then allows
them to implement their own individual solutions for the field
power section.
This option cannot be ordered for units with rated DC currents
from 15 to 30 A.
L11
2Q field power section
For applications that demand highly dynamic field current
changes, by specifying option L11, the SINAMICS DC MASTER
can be equipped with a two-quadrant field with active current
reduction. Further, this field power section has an integrated
field overvoltage protection function.
This option cannot be ordered for units with rated DC currents
from 15 to 30 A.
L15
External sensor for the ambient or inlet temperature
Option L15 is a sensor located outside the unit to measure the
ambient or inlet temperature. For example, this can be used to
simply monitor the cabinet temperature and/or identify when the
air intake filter is blocked.
L20
Unit without fan
With option L20, units with a rated DC current of 1500 A or higher
can be ordered without a fan.
Note: Measures must be taken to ensure a volumetric air flow
rate which is at least equal to the cooling air requirement
specified in the technical specifications.
L21
Fan for single-phase connection
A fan can be optionally supplied with a single-phase connection
for units with rated DC currents between 400 and 1200 A. This
allows fans to be more quickly replaced than three-phase fans –
especially as the direction of rotation does not have to be
checked.
Rated supply voltage: 230 V 1 AC ± 10 %
(50 and 60 Hz)
Units smaller than 400 A are self-ventilated or have an integrated
24 V DC fan. Units with ratings of greater than 1200 A require a
three-phase connection for the fan due to the higher power
consumption.
L85
85 A field power section
With option L85, users can have the SINAMICS DC MASTER
equipped with a rated DC field current of 85 A.
This option can only be ordered for units with rated DC currents
from 1500 to 3000 A.
M08
Coated PCBs
In order to improve the reliability for increased degrees of
pollution and climatic stressing, it is possible to order PCBs of
the SINAMICS DC MASTER that are coated on both sides by
specifying option M08.
M10
Nickel-plated copper busbars
When ordered with option M10, the SINAMICS DC MASTER
is equipped with nickel-plated copper busbars. The degree of
availability can be increased for aggressive atmospheres.
This option is not available for units with rated DC currents from
15 to 30 A.
