2 x M, L1, L2 (X105 –X108) for wire cross-sections of 4 up to max. 16 mm resp. AWG 12 - 4 are disposable at every SIPLUS PSU. The feeder terminals and the branch terminals for the adjacent cabinet are internally linked. -
Page 11: Switching Off The Supply Outputs
An activating of the electronic supervision is signaled by the channel LED with a red continuous light. In addition at the signaling outputs MELD (active HIGH) and MELD_N (active LOW) a collective sta- tus signal is output.

SIPLUS PSU internally. The connection between M potential and cabinet earth is established by mounting the PSU at the cabinet rack. For use of the SIPLUS PSU in plants with central earthing point the internal connection between M potential and unit casing can be disconnected. -
Page 15: Technical Data
When using cabinets it is recommended to install the SIPLUS PSU in the lowermost tier. The maximum ambi- ent temperature in dependency of the consant current through the feeder diodes is to be considered according to derating in chapter 6.1. -

As an option an external pullup can be connected to the MELD_N output in order to generate H- levels when feeding voltage driven inputs (see fig. 10). The application impedance and the MELD_N leakage current have to be considered here among other constraints.

SIPLUS PSU (6DL3500-8BA) 6.2 Installation into the cabinet When operating the SIPLUS PSU in I & C cabinets the installation in the lowermost tier is recom- mended. The supply cables and transfer cables to the neighboring cabinet are connected vertically from below. -
Page 21: Commissioning
For the horizontal mounting position choose the position with the longest distance to the rear assembly wall in order to get an optimum heat dissipation via airflow at the heat sink.

24 V supply voltage. At the auxiliary supply unit an output voltage of 30 V and a current limitation of 60 A must be adjustable. Repair of faulty feeding diodes is not provided. In that case the SIPLUS PSU must be replaced by a new unit (see chapter 8.5 “Replace of an Equipment”). - Page 26 Connect the supply cable to L2 again. Note: The supply cable at L1 must be connected during the whole test step for the supply of the neighbor cabinet!
