Options
W02
Cooling unit with redundant stainless steel plate-type
heat exchangers (for water cooling)
The cooling unit is used to dissipate the power loss from the con-
verter and consists of two cooling circuits: the internal cooling
circuit with deionized water and the external raw water circuit for
dissipating the power loss. In the standard version the internal
cooling circuit has two redundant circulating pumps and one
stainless steel plate-type heat exchanger. With option
W02
, a
second stainless steel plate-type heat exchanger is integrated to
enable fully redundant operation.
W11
Cooling unit with a titanium plate-type heat exchanger
(for water cooling)
If the raw water specified in the Technical specifications is not
available for the cooling unit, option
W11
must be selected. This
is required in the case of aggressive raw water such as sea-
water, for instance. With option
W11
, a titanium plate-type heat
exchanger is installed instead of the stainless steel plate-type
heat exchanger. The three-way valve for preventing condensa-
tion and the necessary pipe connections are still made from
stainless steel.
Notice:
When option
W11
is chosen, the piping on the raw water side is
manufactured of stainless steel and not titanium.
W12
Cooling unit with redundant titanium plate-type
heat exchangers (for water cooling)
With option
W12
, two completely redundant titanium plate-type
heat exchangers are integrated for the internal cooling circuit
(other characteristics as described under option
W11
).
Notice:
When option
W12
is chosen, the piping on the raw water side is
manufactured of stainless steel and not titanium.
W14
Converter without cooling unit. This must be provided on the
plant side (for water cooling)
When option
W14
is chosen, the water-cooled converter is
supplied without a cooling unit. The necessary cooling system
must be provided on the plant side.
Note:
Option
W14
reduces the width and weight of the cabinet
(data available on request).
W20
Raw-water connection from the bottom
(SINAMICS GM150 in the IGBT version)
Option
W20
enables the raw water for the cooling unit to be
supplied from the bottom through the cabinet floor with a flange
connection. The necessary mating flanges are included as a
pack with the cooling unit.
Note:
With water-cooled IGBT converters, the raw water is supplied to
the cooling unit through the side panel from the left-hand side.
For converters in IGCT technology, the raw water is connected
at the cooling unit from the bottom.
Y05
Customer-specific rating plate
With option
Y05
the data on the rating plate can be adapted for
the specific plant or system, depending on the ambient condi-
tions such as installation altitude or ambient temperature. This
also involves data regarding the rated voltage, rated current and
the frequency range at the converter output. The maximum
values of the adapted rating plate are defined by the values of
the standard rating plate, which correspond to the catalog data.
Y09
Special paint finish according to RAL...
Converters are normally supplied in RAL 7035 (light gray).
With option
Y09
a special color can be ordered by specifying
plain text.
Note:
For SINAMICS GM150 in the air-cooled version, the following
applies: The fans still have the standard RAL 7035 color even
when the cabinet has a special paint finish.
Y10
Customer-specific circuit diagrams
The circuit diagrams are given customized headers.
The data for the header must be specified in plain text
(up to three lines, with 45 characters per line).
