The SINAMICS DCM Control Module consists of 2 plates.
Modules in the front plate:
● Power interface (C98043-A7109)
● Control Unit (CUD)
● BOP20 Operator Panel
● Second CUD (optional)
● Communication Board(s) CBE20 (optional)
Modules in the rear plate:
● Fuse monitoring equipment (C98043-A7118)
● Voltage measurement equipment (C98043-A7117)
● Firing pulse transformer module (C98043-A7043)
The two plates can be mounted at a distance from each other in the system, if required.
The firing pulse transformer module can be physically divided. This means parts of it can be
mounted outside the unit itself in the area around the power unit.
A few examples are given below:
Note
The SINAMICS DCM Control Module is supplied with front and rear plates mounted one on
top of the other. The correct cables (connectors X21A, X22A, XS20, XS21, and X102) for
this mounting type are already in place.
Refer to Chapter 2 for cable ordering information if plates are being mounted in accordance
with the examples below.
Note
Firing pulse cables (X11...X16, X21...X26)
The firing pulse cables should not be shielded.
If shielding is required, the shield is not connected to ground, but is connected to the
auxiliary cathode of the particular thyristor. This shield must be adequately insulated with
respect to its environment as it is at the full line supply voltage including the hole storage
effect peaks.
