Installation After A Long Storage Time - Siemens SINAMICS G120C Operating Instructions Manual

Additional requirements placed on the protective conductor
• For permanent connection, the protective conductor must fulfill at least one of the following
conditions:
– The protective conductor is routed so that it is protected against damage along its
– As a conductor of a multi-conductor cable, the protective conductor has a cross-section ≥
– For an individual conductor, the protective conductor has a cross-section ≥ 10 mm² Cu.
– The protective conductor consists of 2 individual conductors with the same cross-section.
• When connecting a multi-core cable using an industrial plug connector according to
EN 60309, the protective conductor must have a cross-section of ≥ 2.5 mm² Cu.
• Observe the local regulations for protective conductors subject to a high leakage current at
the installation site.

Installation after a long storage time

Overview
To avoid extra duties, Siemens recommends to run the converter for an hour with 100% main
supply voltage once a year. If the converter has not been in operation for too long, you must form
the DC link capacitors before switching the full mains voltage to the converter.
Precondition
Form the DC-link capacitors in the following cases:
• The converter was not operational for longer than one year.
• The date of manufacture of the converter was more than one year ago when installing the
converter for the first time.
The date of manufacture of the converter is coded in positions 3 - 6 of the serial number.
