Safety Locking System (Option M10); Power Cable Connection At The Drive Input From Above (Option M13); Signal And Control Cable (Max. 2.5 Mm²) (Option M32); Ip54 Degree Of Protection (Option M54) - Siemens Sinamics GM150 6SL3835-2LN44-2AA0 Operating And Installation Instructions

3.6.27

Safety locking system (option M10)

The safety locking system is based on the key transfer system developed by Castell. It is a
supplementary mechanism to the electromechanical door locking system integrated as
standard. The medium-voltage breaker must be opened before access can be gained to the
coded key of the key exchange unit. The opened medium-voltage breaker releases the key to
the key exchange unit. This key enables the access to the keys for the cabinet doors of the
power unit. This key interlocking system ensures that the converter is disconnected from the
medium-voltage supply and that no cabinet components are connected to medium voltage. As
long as the cabinet doors are not closed again and the keys to the power-unit cabinet are not
inserted back in the key exchange unit, the key for the medium-voltage breaker will not be
released. The medium-voltage breaker cannot be switched on again.

Power cable connection at the drive input from above (option M13)

You can introduce the line-side power cable into the cabinet from the top.
3.6.29 Signal and control cable (max. 2.5 mm²) (option M32)
Signal and control cables are connected directly to the terminals on Terminal Module TM31 or
TM15 as standard. The maximum connectable cross-section for these cables to the TM31 and
TM15 Terminal Modules is limited to 1.5 mm
With option M32, you can connect signal and control cables with connection cross-sections of
up to 2.5 mm
3.6.30

IP54 degree of protection (option M54)

This option increases the degree of protection of the drive from IP43 to IP54.
3.6.31

Redundant fan in the power unit (option M61)

To increase the plant availability, an additional redundant fan is installed. The differential
pressure sensing function in the cabinet immediately identifies if a fan in the cabinet fails. The
open-loop control system switches on the redundant fan so that the drive system does not fail.
This prevents production failures or interruptions. The replacement of the defective fan can be
postponed to the next planned stoppage.
