Options
New options
A70
Thermo switch for the de-excitation resistor
With option A70, the de-excitation resistor is equipped with an additional thermo
switch, and is monitored by the SICROWBAR overvoltage protection.
When the de-excitation resistor is overloaded, the SICROWBAR overvoltage
protection initiates an EMERGENCY STOP (disconnects the voltage) in the
excitation converter.
C60
Rated line frequency 60 Hz
The option C60 must be selected, if the line frequency of the armature and
auxiliary circuits is 60 Hz instead of 50 Hz. The motor protection circuit breaker of
the unit fan is adapted appropriately.
G24
PROFINET interface (via CBE20)
Option G24 includes the SINAMICS Communication Board CBE20 for connection
to PROFINET.
L06
Internal generation of 24 V DC
The option L06 includes the internal generation of the 24 V DC supply voltage from
the auxiliary 230 V 1 AC, 50/60 Hz voltage supply using a switched-mode power
supply.
L88
Ground fault monitoring with analog output
See section 8.1.2 for a description.
Updated option description
Y17
Line reactor
The statements of footnote 2) for option Y17 on catalog page 7/7 change as
follows:
2)
The option Y17 is only available for the excitation units 6RN8011-2SE41-2AA0
and 6RN8011-5SE36-0AA0.
With option Y17, the cabinet size can vary depending
on the reactor
and the continuous rated current can be smaller as given in the
following tables
