SINAMICS G150
Drive converter cabinet units
75 kW to 2700 kW
Description of options
Further descriptions of the options are provided in the
SINAMICS Low Voltage Engineering Manual.
B00, B02, B03
Options compliant with NAMUR requirements
Exclusion list with other options:
The following restrictions and exclusions applicable to the
NAMUR terminal block
B00
with regard to other available
options must be taken into account.
With options such as
L50, L55, L86
, the connection is made as
described in the standard. There is no wiring to the NAMUR ter-
minal block.
Notice:
In addition to option
B00
for supply disconnection, option
L13
for currents
≤
800 A or option
L26
for currents > 800 A must be
ordered. For converters with power units connected in parallel,
electrical separation from the line supply is included as stan-
dard.
B00
NAMUR terminal block
The terminal block has been designed and implemented in ac-
cordance with the requirements and guidelines of the Standards
Working Group for Instrumentation and Control in the Chemical
Industry (NAMUR Recommendation NE37), i.e. certain functions
of the device are assigned to specified terminals. The inputs and
outputs connected to the terminals fulfill PELV requirements
("protective extra-low voltage with protective separation").
The terminal block and associated functions have been reduced
to the necessary minimum. Unlike the NAMUR recommendation,
optional terminals are not available.
The 24 V supply is provided on the plant side via terminals
-A1-X2:1-3 (fused in the converter with 1 A). It must be ensured
that the PELV safety requirements are fulfilled (protective extra-
low voltage with protective separation).
For temperature monitoring of explosion-proof motors, option
B00
includes a PTC thermistor evaluation unit. Exceeding the
limit value causes a shutdown. The associated PTC sensor is
connected to terminal -A1-X3:90, 91.
In parallel to operation via the NAMUR terminal block, there is
also the option to operate the converter via the communications
interface provided as standard on the CU320-2 Control Unit. The
PROFIdrive profile "Process engineering" employed in the chem-
ical industry can be selected by macros.
Remark
on the option
Reason
L45, L57, L59,
L60
An EMERGENCY OFF Category 0 is already provided in
the NAMUR version.
The forced line supply disconnection is connected at
terminal -A1-X2: 17, 18.
L83, L84
A thermistor evaluation unit (trip) is already included as
standard with option
B00
.
L19
Alternatively, option
B03
can be selected. This means that
a reduced scope is available for external auxiliaries.
L87
The insulation monitor monitors the complete electrically
coupled network. This combination is available on
request. An insulation monitor can also be provided on
site.
G60
A TM31 Terminal Module is already included as standard
with option
B00
.
