does G110 FSAhas "Y" cap? if it has, how to remove it? in the G110 manual, i just find that FSB and FSC can remove the "Y" cap. |

Hyyeyelin,tractor, Yes it has; but why do you need to remove it? The ‘Y’ – capacitor has to be removed, when using the SINAMICS G110 FSB and FSC on ungrounded supplies = IT-Supply G110 FSA can’t be used on ungrounded IT-supply! A description how to remove the Y’ Capacitor Link you will find in the manual under: A Removal of ‘Y’ Capacitor Link |

Hello yeyeling, SINAMICS G110 inverter has been developed for operation on grounded line supplies. They are equipped with noise suppression capacitors between the line supply input and the ground which results in a ground leakage current of approx. 20mA (this depends on the particular drive unit) To reduce the leakage current you have to use a Filter class B with low leakage currents (available additionally for inverters with integrated filter) With this filter, the inverter complies with the emission standard EN 55011, class B for conducted interference. The leakage currents are reduced to < 3.5 mA Please have a look into the catalogue (http://www.automation.siemens.com/sd/portal/html_76/support_kataloge.htm) chapter 2/8 & 2/13 for Order numbers pls look into chapter 2/14 (the other possibility is to disconnect the ground and mount the inverter on a isolated mounting plate, but this is a bit dangerous) |
