Emc-Compliant Installation Of Sinamics Dcp (Installation Instructions) - Siemens sinamics dcp Operating Instructions Manual

Electrical connection
6.1 EMC-compliant installation
SINAMICS DCP devices satisfy the requirements for interference emission and interference
immunity defined in EN 61800-3 for the second environment (Category C3) and those in the
generic standards EN 61000-6-2 and EN 61000-6-4.
In a residential environment, this product can cause high-frequency disturbances, which
may make interference suppression measures necessary.
6.1.2

EMC-compliant installation of SINAMICS DCP (installation instructions)

General information
In order to ensure electromagnetic compatibility (EMC) in rugged electrical environments and
adhere to the standards required by the relevant legislating body, the EMC rules listed below
should be followed during the construction and installation stages.
Grounding of the DC link
The DC link does not have to be grounded. (for a 30 kW device from product version 02).

WARNING
Interconnect all metallic parts of the control cabinet highly conductively and with a large
contact area. (not paint on paint!). Use contact or scratch washers if necessary. The
cabinet door must be connected to the cabinet using the shortest possible ground strips
(at the top, center, and bottom).
Contactors, relays, solenoid valves, electromechanical operating hours counters, etc.,
in the cabinet and - where applicable - in neighboring cabinets - must be provided with
quenching combinations such as RC elements, varistors, and diodes. These must be
connected directly at the appropriate coil.
Whenever possible, lead signal cables
Unshielded cables in the same circuit (supply/return conductors) must be twisted where
possible, or the area between them must be minimized, to avoid creating loop antennas
unnecessarily.
Connect spare wires to the cabinet ground
shielding effect.
Avoid unnecessary cable lengths in order to keep coupling capacities and inductances
low.
Crosstalk is generally reduced if the cables are laid close to the control cabinet ground.
Therefore, do not route cables freely around the cabinet, but lay them as close as pos-
sible to the cabinet enclosure / mounting plates. This also applies to spare cables.
