 却风扇：取决于电机制造商/当地需求
-继电器逻辑：取决于本地需求
使用保险丝F1是因为C1和C2型转换器结构没有内置保险丝。所有组件，可通过115/230 V供电
将由一台隔离变压器T2供电。所有组件均设置为230 V电源或选择用于此电压水平。不同的
耗电元件是单独熔断的。只要T2有正确的分接头，它就可以连接到电源，用于给转换器的电源部件供电。
这同样适用于现场供电电路。有两种不同类型的匹配变压器可用。一个可用于电源电压a： 生成ON/OFF和START/STOP命令：
K20和K21（闭锁接口继电器）代表的命令可由PLC生成，并传输至转换器的端子
通过继电器进行电流隔离或直接使用24V信号。没有必要使用硬接线信号。这些命令可以是
也通过串行链路系统传输。通过为一个或另一个信号选择一个或其他可能性，甚至可以实现混合解决方案。
b： 控制和监测信号的生成：
电枢电路的主电源接触器K1由位于电子电源板上的干触点控制。此接触器的状态
由转换器通过二进制输入3进行检查。励磁电源接触器K3由连接至
转换器。二进制输出由继电器驱动器组成，能够提供近似值。每个50 mA，所有输出的电流限制约为160 mA。
接触器K6和K8控制驱动系统的风扇。它们由辅助触点K10（类似于K11）控制。与K6串联的是
断路器F6的辅助触点，用于监控电机风扇电源。用于监控温度触点的转换器风扇电源
探测器与K8串联使用。使用辅助触点K6和K8，并将其连接到二进制输入1和2，以监测风扇电源的状态
通过转换器。K15的功能描述见
高500 V，另一个电压高690 V。不要将690 V一次分接与SDCS-FEX-1/2A现场电源一起使用！

 - Typical configuration for high power drives connected in
12-pulse parallel Master-Follower application
(see chapter 3.6)
This configuration shows a 12-pulse parallel drive system. It is an
easy option to increase the power of a drive system. Depending on
the engineering features , redundancy or emergency operation, if
one converter fails, is made available.
Such drives use two identical 6-pulse converters and an especially
designed choke called T-reactor or 12-pulse choke or interface
reactor. The conv a: Generation of the ON/OFF and START/STOP command:
The commands represented by K20 and K21 (latching interface relay) can be generated by a PLC and transferred to the terminals of the converter either
by relays, giving galvanic isolation or directly by using 24V signals. There is no absolute need to use hardwired signals. These commands can be
transferred via a serial link system too. Even a mixed solution can be realized by selecting the one or the other possibility for the one or the other signal.
b: Generation of control and monitoring signals:
The main power contactor K1 for the armature circuit is controlled by a dry contact located on the electronic power supply board. The status of this contactor
is checked by the converter via binary input 3. The field supply contactor K3 is controlled by the auxiliary contact K11 connected to a binary output of the
converter. The binary outputs consist of relay drivers, capable to give appr. 50 mA each and a current limitation of around 160 mA for all of the outputs.
The contactors K6 and K8 control the fans of the drive system. They are controlled by the auxiliary contact K10 (similar to K11). In series with K6 is an
auxiliary contact of the circuit breaker F6, which monitors the motor fan supply. For the converter fan supply monitoring the contact of the temperature
detector is used in series with K8. Auxiliary contacts K6 and K8 are used and connected to the binary inputs 1 and 2 to monitor the status of the fan supplies
by the converter. The function of K15 is described at
