Siemens SINAMICS G120P Operating Instructions Manual page 12

General
NOTICE
Do not interchange the I/Os
The connections must not be interchanged:
connect the incoming line cable to LINE/NETZ L1, L2, and L3 and the outgoing cable to the
line reactor to LOAD/LAST L1', L2', L3'.
If this is not observed, the line filter may be damaged.
If you are carrying out work on the line filter, you must wait for the discharge time to elapse
(approx. 5 mins). The line filter must not be short-circuited to reduce the discharge time.
NOTICE
High leakage current
The line filters listed conduct a high leakage current via the PE conductor. A permanent PE
connection for the line filter or control cabinet is required due to the high leakage current of
the line filters.
According to EN 61800-5-1, Section 6.3.6.7, the minimum cross-section of the protective
ground conductor must conform to the local safety regulations for protective ground
conductors for equipment with a high leakage current.
Note
High-voltage test
If a high-voltage test is conducted with alternating voltage in the system, the line filter must
be disconnected to obtain correct measurement results.
NOTICE
Use only approved line filters
Using line filters not approved by SIEMENS for SINAMICS can lead to line-side harmonics
that can interfere with or damage other loads powered from the network.
NOTICE
Component cooling
Provisions for component cooling must be made at the installation site. Power loss data is
given in the technical specifications.
