Options
L48
Make-proof grounding switch at the converter input,
motor-operated (SINAMICS SM150 in IGBT version
on request only)
If grounding on the infeed side is required for safety and protec-
tion reasons, a motorized make-proof grounding switch can be
ordered under code
L48
. The number of make-proof grounding
switches depends on the particular infeed version (12/24-pulse
for SINAMICS GM150 or 6-pulse for SINAMICS SM150).
For safety reasons, the converter controller locks these ground-
ing switches against activation while voltage is still present. The
control is integrated into the protection and monitoring chain of
the converter. The grounding switches are inserted automati-
cally when the standard grounding switches of the DC link are
inserted.
In the event of maintenance work on the converter, it must be en-
sured on the plant side that there is no external voltage present,
e.g. auxiliary voltage for fans, the cooling system, controller and
closed-loop control and any external outputs in the converter.
Notice:
With option
L48
the cabinet width is increased as follows:
•
SINAMICS GM150 in IGBT version:
600 mm
•
SINAMICS GM150 in IGCT version:
2 × 700 mm per converter unit
•
SINAMICS SM150 in IGCT version:
700 mm per converter unit
Note:
Option
L48
in conjunction with option
C55
(auxiliary power
supply for open-loop and closed-loop control) on request.
Note:
For SINAMICS GM150 in IGCT version, option
L48
in
conjunction with option
N15
(24-pulse Basic Line Module)
on request.
L49
Make-proof grounding switch at the converter output,
motor-operated (SINAMICS SM150 in IGBT version
on request only)
In certain operating modes/versions of the load machine (e.g.
drive line-up with gas turbines) and types of drive motor (e.g.
PEM), operating statuses may occur in which there is a risk that
energy is fed back to the converter by the motor This can lead
to dangerous voltages. In these cases a motorized grounding
switch for the converter output side can be ordered under code
L49
. Where power units are connected in parallel, the number of
circuit breakers will rise accordingly.
For safety reasons, the converter open-loop control locks the
grounding switch against activation while voltage is still present.
The control is integrated into the protection and monitoring chain
of the converter. The grounding switches are inserted automati-
cally when the standard grounding switches of the DC link are
inserted.
Notice:
With option
L49
the cabinet width is increased as follows:
•
SINAMICS GM150 in IGBT version:
600 mm
When options
L51
or
L52
are simultaneously selected, the width
does not have to be increased.
•
SINAMICS GM150 in IGCT version and
SINAMICS SM150 in IGCT version:
700 mm per converter unit
When options
L08
and/or
L51/L52
are simultaneously selected,
the width does not have to be increased.
Note:
Option
L49
in conjunction with option
C55
(auxiliary power
supply for open-loop and closed-loop control) on request.
