2.6.36 Base 100 mm high
Because
it is raised 100 mm, the supplementary cabinet base allows for greater bending radii
for cables (cable inlet from below) and cable routing within the base.
Note
You can find a description of the base in the "SINAMICS S120 Cabinet Modules" Manual,
Chapter, "Options / M06, 100 mm high base, RAL 7022".
2.6.37 Anti-condensation heating
The
anti-condensation heating is used at low ambient temperatures and high levels of humidity
to prevent condensation from forming.
Note
You can find a description of the anti-condensation heating in the "SINAMICS S120 Cabinet
Modules" Manual, Chapter, "Options / L55, cabinet anti-condensation heating".
2.6.38 Current transformer upstream of the main switch
The current transformers are used for measuring and monitoring purposes. For the Line
Connection
Modules, the current transformers are installed upstream of the main switch in all
three line phases of the infeed.
The current transformers have an accuracy class of 1.0. The secondary current is maximum
of 1 A.
Note
You can find a description of the current transformers in the "SINAMICS S120 Cabinet
Modules"
Manual, Chapter, "Options / L41, current transformers upstream of the main switch".
2.6.39 Voltage Sensing Module VSM10
The
VSM10 Voltage Sensing Module allows the line supply or motor voltage characteristic to
be precisely sensed. In addition, the VSM10 is used to switch to a rotating synchronous motor
– or for a quick flying restart of rotating induction motors (flying restart function).
Note
You can find a description of the VSM10 in the "SINAMICS S120 Cabinet Modules",Manual,
Chapter "Options / K51, Voltage Sensing Module Cabinet-Mounted VSM10".
