1C31129G03 Output the electronic module

The grounding bar is used for high–resistance connection and balancing of the DC link to the ground. It must always remain inserted. The grounding bar must be opened only if a high–voltage test is performed Electrically disconnecting the line supply from the power circuit of the drive group using the internal line contactor. The coil circuit can be disconnected in order to reliably open (de–energize) the line contactor using external electrically isolated contacts via terminals NS1, NS2 at the NE module. The DC link is not pre–charged if the connection is missing when the unit is powered–up. The state of the contactor (whether it is open/de–energized) can be interrogated using terminals 111, 113, and 213. The NS1, NS2 connection may only be opened if terminal 48 and/or terminal 63 are de–energized using a leading contact, or is simultaneously opened when these terminals are de–energized, refer to Section 8.7.

Infeed modules

A maximum of six terminals 48 can be connected in parallel with one another in order to shut down a maximum of six NE modules with one leading contact of the main switch. Maximum cable length with a 1.5 mm2 cross–section: 150 m (2–wire conductor If enable signal terminals, e.g. terminal 663, are connected in parallel to terminal 48, then the number of NE modules must be appropriately reduced due to the higher current load connected to terminal 9. Note If the internal power supply at NE module 1 fails, then the remaining NE modules and drives that are connected are also inhibited. The drives ”coast down” unbraked. As an alternative to the limited current capability of the internal power supply via terminal 9, the enable voltage can be taken from an external 24 V PELV power supply. In this case, the terminals 19 of the NE modules must be connected to the 0 V reference potential (ground) of the external power supply

connection of the line contactor

 The infeed modules include an integrated line contactor that is listed in the Catalog. The line contactor is electronically controlled (energized) via terminal 48. In order to safely and reliably disconnect the DC link from the line supply, e.g. for stopping in an emergency situation, the coil circuit of the line contactor must additionally be interrupted via terminal NS1–NS2 using electrically isolated (floating) mechanical switching elements. This means that the electronic control has no influence when shutting down with electrical isolation. The cable routing to the connecting terminals must be safely and electrically de–coupled from the electronics. Before or at the same time that connection NS1–NS2 is interrupted, the line contactor must always be opened using terminal 48. The NC contact 111–213 of the line contactor, positively–driven with the power contacts, must be included in the feedback circuit of the external, safety–relevant EMERGENCY STOP switchgear combination (safety relay). This means that the function of the line contactor is cyclically monitored
