Siemens SINUMERIK 840D sl Manual page 141

Multiple Control Supply Modules are recommended for larger plant concepts. This achieves
a decoupling and reduces possible influencing of the supplied components amongst each
other.
Example: Subdivision of the consumer groups:
● CSM for the direct drive system (CU, Line Module, Motor Module and SMC)
● CSM for additional consumers, such as brakes, valves and power contactors
Example: Division of the protection (e.g. automatic devices) for the consumer lines
● NCU
● Supply of the Sensor Modules
● Consumers such as relays, valves, etc.

Danger
The Control Supply Module has two supply circuits!
Risk of electrical shock. Dangerous voltage present for as long as five minutes after the
supply has been switched off.
The protective cover may be opened only after this time has expired.
When the protective cover of the DC link is opened, ensure that the unlatching is
activated. An appropriate tool, such as a screwdriver, must be used.
The components may be operated only when the protective covers of the DC link are
closed. Damaged components (for example, with defective locking of the protective
cover) must not be continued to be used.
The non-observance can cause death or severe injury.
Caution
The danger note for the DC link discharge time must be placed on the component in the
national language.
A set of labels in 16 languages is provided with the component.
