Safety interlocking system
The safety interlocking system is based on the key transfer
system developed developed by Castell. It is a supplementary
mechanism to the electromagnetic door locking system inte-
grated as standard. To obtain the coded key of the key ex-
change unit, the medium-voltage circuit breaker must first be
opened. The opened medium-voltage circuit breaker releases
the keys to the key exchange unit, which in turn releases the
keys to the converter cabinet doors of the power unit. This
ensures that the converter is isolated from the medium voltage
and that the medium voltage is no longer present in the cabinet.
As long as the cabinet doors are not closed again and the keys
of the converter cabinet doors are not put back into the key
exchange unit, the key for the medium voltage circuit breaker will
not be released and the medium voltage circuit breaker cannot
be reclosed.
M11
Dust protection (air-cooled converters)
With option
M11
the cabinet doors are fitted with additional filter
mats to prevent the ingress of dangerous dusts that would
otherwise be deposited on the power unit components. The filter
mats are fitted to the outside of the cabinet doors, which means
that they can be replaced during operation.
A differential pressure technique continually determines the
amount of dust in the filter mats. A maintenance request is
issued in plenty of time before the filter mats get clogged up.
When replacing the filter mats, it must be ensured that no dust
gets into the cabinet unit through the air pulled in by the cabinet
fans as they run.
Note:
For SINAMICS SM150 in the IGCT version, the filter mats are
already included as standard.
M13
Power cables are connected at the converter input from the top
(SINAMICS GM150 in the IGBT version)
Given suitable installation conditions, option
M13
enables the
line-side power cable to be introduced into the cabinet unit from
the top.
Notice:
Option
M13
increases the width of the cabinet unit by 600 mm.
When simultaneously selecting option
L08
(output reactor) or
Y15
(sine-wave filter) the width does not increase. In the case of
option
Y15
, the dimensions in the Technical specifications apply.
Note:
Option
M13
is included in option
M78
(power cable connection
at the converter output from the top).
M16
Extended dust protection
(SINAMICS GM150 in a water-cooled IGBT version)
Opening the cabinet doors before commissioning (e.g. to route
connecting cables) can mean, in certain environments, that the
converter is polluted, for example as a result of welding opera-
tions. Option
M16
involves installing a dust protection cover
manufactured out of polycarbonate (Makrolon) inside the con-
verter. This dust protection cover reduces the amount of pollu-
tion that can get to the converter components through open
doors, therefore minimizing cleaning costs for the converter.
Note:
The commissioning personnel must remove the dust protection
cover of the converter prior to commissioning.
M32
Customer's terminal strip with spring-loaded terminals
for signal cables up to 2.5 mm
2
The signal cable is normally connected directly to the terminals
of the TM31 or TM15 Terminal Modules. It must be noted that the
maximum connectable cross-section for TM31 and TM15 is
limited to 1.5 mm
2
.
With option
M32
, the signals are fed to a terminal strip with
spring-loaded terminals. In this case connection cross-sections
of up to 2.5 mm
2
are permitted.
Note:
In conjunction with options
G61
,
G62
and
L80 to L96
, it is not
possible to lead out the signals from the additional Terminal
Modules.
M33
Customer's terminal strip with screw terminals for signal
cables up to 2.5 mm
2
The signal cable is normally connected directly to the terminals
of the TM31 or TM15 Terminal Modules. It must be noted that the
maximum connectable cross-section for TM31 and TM15 is
limited to 1.5 mm
2
.
With option
M33
, the signals are fed out to a terminal strip with
screw terminals. In this case connection cross-sections of up to
2.5 mm
2
are permitted.
Note:
In conjunction with options
G61
,
G62
and
L80 to L96
, it is not
possible to lead out the signals from the additional Terminal
Modules.
