4.3 Protective conductor connection and potential equalization
Requirement
You have mounted the Control Unit in the control cabinet.
The SIMOTION D410-2 control unit has a protective conductor connection (M4 screw, Torx
T20). This connection is also for the connection of an equipotential bonding conductor.
Note
Requirements for functional safety for machines and systems; reliability and EMC are only
guaranteed with original SIEMENS cables.
DANGER
Danger to life from energized parts
Death or serious injury will result if energized parts are touched.
Turn off and lock out all power supplying this device before working on this device.
Protective conductor connection
SIMOTION D and the SINAMICS S120 drive system are designed for use in cabinets with a
protective conductor connection.
All system components and machine parts must be incorporated in the protection concept.
The
drive line-up must be arranged on a common bright mounting plate ① in order to comply
with the EMC limit values. The connection ② establishes a low-impedance connection to the
mounting plate.
The mounting plate must be connected to the protective conductor connection of the control
cabinet. For this purpose, a connection ③ must be established to the protective conductor bar
④. The protective conductor bar ④ must be connected to the protective conductor ⑤.
The protective connection (PE connection) that is used for the motors ⑥ must be established
through the motor cable.
For EMC reasons, the motor cable shield must be laid flat at both the Motor Module (MM) /
Power Module (PM) and motor.
A protective connection ⑧ must also be established for components that are not connected
with low impedance (e.g. control cabinet door via hinges ⑦).
Example: Booksize axis grouping comprising Control Unit (CU), Line Module (LM), and Motor
Modules (MM) as well as drive in blocksize format comprising a Power Module (PM) with
snapped on Control Unit (CU)
