Overview
Accessories for grounding and short-circuiting the
converter for commissioning and maintenance work
For safety reasons, devices for grounding and short-circuiting
the converter are required for work on the converter in the de-en-
ergized state (EN 61230/VDE 0683-100 (IEC 61230)). They are
required for commissioning or service work, for example, as well
as for replacing fans or Power cards/phase modules.
As some of this work has to be performed by operator personnel
with the relevant training, the specified tools must be available
on the equipment. If these devices are not available, the work
must not be performed due to the electrical hazards.
In the case of SINAMICS GM150 and SINAMICS SM150, spher-
ical grounding points are fitted on the input and output side in
the area of the connecting bar which can be short-circuited and
grounded with an appropriate three-pole grounding device
(grounding harness).
As a rule, this must be done in the de-energized state for all work
(in the case of converters with a power unit connected in parallel
at both infeed points or motor feeders).
If appropriate devices are not available on the equipment, the
relevant converter accessories must be supplied in the requisite
quantity.
Please note in this case that the number of three-pole grounding
devices required is dependent on the number of infeeding three-
phase current systems. One grounding device per three-phase
current system is required.
If there is a risk of power being fed from the motor side back into
the converter, one grounding device per three-phase current
system must be fitted here as well.

Accessories for replacing phase modules
(SINAMICS GM150 in the IGCT version and
SINAMICS SM150 in the IGCT version)
The phase modules of the converters with IGCT power semi-
conductors (SINAMICS GM150 in the IGCT version and
SINAMICS SM150 in the IGCT version) can be completely
replaced by trained personnel. To replace, the entire phase
module must be extracted from the converter using a special
lifting tool and transported on a stacker truck.

Overview
The following versions are available as static excitation units
for SINAMICS GM150 and SINAMICS SM150:
•
Static excitation unit for separately excited synchronous
motors with brushless rotating reverse-field excitation
•
Static excitation unit for separately excited synchronous
motors with slipring excitation
Control with both versions is performed by the converter through
a PROFIBUS interface.
A static excitation unit must always be ordered together
with the converter but it has its own order number.
Add "-Z" to the order number of the converter and specify
the code E01 or E02.
The static excitation unit cannot be ordered on its own.
Note:
The option
G30
(PROFIBUS master) must also be ordered in
conjunction with SINAMICS GM150.
