M10
Mechanical door interlock – Castell
With option
M10
the drive is supplied with a mechanical door
interlock system.
The safety closing/interlocking system is based on the key trans-
fer system from Castell. The opened circuit breaker releases the
key for the key exchange unit, which in turn releases the keys to
the drive cabinet doors of the power section. This ensures that
the drive is isolated from the medium voltage and that the
medium voltage is no longer present in the cabinet.
Note:
The units have as standard an electrical door interlock.
M12
Electrical door interlocks
The electrical door interlock system prevents access to the
energized sections in the drive as long as hazardous voltages
are present. This system also prevents the drive from being
switched on until all doors of the energized sections in the drive
are closed. It is possible to monitor the internal (options
N44
,
N45
) or external grounding switch.
Note:
Option
M12
is required for the CE mark, and is included in option
U02
. For drive units supplied from Nuremberg, Germany, these
must be ordered with CE mark. As a consequence, option
M12
is not
separately available.
M35 to M37
Gland plates
With options
M35
,
M36
and
M37
, gland plates can be ordered in
aluminum (
M35
), brass (
M36
) and stainless steel (
M37
) version.
As standard the gland plates are aluminum.
The options
M35
to
M37
are mutually exclusive. One of these
options must be ordered for units manufactured in Nuremberg.
Note:
Options
M35
to
M37
apply for input/output power cables only.
Gland plates for control cables are always aluminum.
M42
IP42 degree of protection
As standard, the air-cooled drives are manufactured in compli-
ance with NEMA 1. The corresponding standard degree of
protection for 6SR4... and 6SR3... drives is IP21.
With option
M42
, the degree of protection for air-cooled 6SR4...
and 6SR3... drives can be increased over what is provided as
standard (NEMA 1 or IP21).
M61
Redundant blower
The drive is equipped with an additional blower to improve the
system availability. If a blower in the drive cabinet fails, the re-
dundant blower is activated by the drive control system prevent-
ing the drive from tripping. This avoids production downtimes or
interruptions. The faulty blower can then be replaced at the next
scheduled shutdown.
Note:
Option
M61
is included in option
U10
(ProToPS).
M64
Drive prepared for connection to an external air discharge
system, front connection
With option
M64
, the drive is prepared for connection to an
external air discharge system at the
front
of the blower assem-
bly.
This option can be used when the customer is providing external
exhaust ducting at the output of the blower to carry the hot air
blowing out of the drive cabinet outside the room.
When configuring the exhaust air ducts for the drive ventilation
system, it is essential to ensure that the air flow rates stipulated
in the technical data are observed. The pressure drop between
the air inlet and air outlet of the drive is different for different ver-
sions. The additional pressure drop due to the external exhaust
air system must lie between 0 Pa and 50 Pa.
Attention:
Note the following regarding the connection of an external air
duct:
•
Suitable openings must be provided in the air duct in order to
be able to replace the fans.
•
It has to be assured that the cabinet doors can be
opened/closed after installing the air duct.
Note:
Selection of option
M64
can affect the sound pressure level
depending on the design of the exhaust air system.
For more information about option
M64
, please contact the
factory or your local Siemens sales representative.
Note:
Option
M64
requires that option
M42
is also ordered (degree of
protection IP42).
Note:
When simultaneously ordering option
L09
, option
M64
is not
valid for the additional reactor cabinet.
