2 Application 2.1 Utilization SIPLUS PSU is a power supply module in electronic cabinets for the feeding and sub-distribution of the power supply DC 24 V. It was developed especially for use in instrumentation and control cabi- nets of the Siemens power station instrumentation and control systems SPPA-T2000 and SPPA- T3000 and the Siemens automation system PCS7.

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.
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.

DC output. The second output requires a pull resistor of 39 kΩ. The pull resistor is the parallel con- nection of 39 kΩ and 100 kΩ and results in 28 kΩ. or with current drawing digital DC inputs (MELD) and current sourcing digital DC inputs (MELD_N) respectively SIPLUS PSU Power Supply Unit A5E00854207E 12 of 30 Copyright (C) Siemens AG 2018 V 8.00 released...

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.
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.
External supply voltage is to be generated as potential free Protective Extra Low Voltage PELV (according to EN 50178).

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.

6.1 Mounting position, heat dissipation and derating According to figure 11 the SIPLUS PSU has to be installed so that a vertical unimpeded flow of the cooling air at the heat sink on the back side of the equipment is ensured.
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.
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.

When changing the equipment, please notice chapter 8.5 “Replace of an Equipment” Step 3: For an optimal cable routing install the SIPLUS PSU in the undermost level. Screw the mounting brackets together with the underground. Tighten the screws with a torque ac- cording to chapter 5.1 “Mechanics”...
7.3 Unearthed Mounting For a mounting isolated from earth (e.g. in plants with a central earthing point) the SIPLUS PSU of- fers the possibility to undo the connection of the reference potential of the DC 24 V supply voltage to the cabinet earth.
