You can choose one of the following modes: (A) Parallel or single mode (B) Selectable overload response, constant current characteristic or latching shutdown (C) Delayed start SITOP PSU400M Manual, 05.2018, C98130-A7601-A1-5-7629 15 Description, device design, dimension drawing 2.5 Selector switch Switch ON OFF A influences the output characteristic in the load range Parallel operation: "Soft" characteristic curve (see Figure 6-7 Output characteristic parallel operation (Page 37)) for the parallel operation of two or more devices: The output voltage falls with increasing output current (namely, also for the overcurrent pulse!). This means that for full output current the highest output voltage can normally no longer be attained. Single operation: B influences the output characteristic in the overload range Latching shutdown: If the output current rises above the rated value and above the current limit, the device reduces the output voltage (see Figure 6-8 Output characteristic latching shutdown (Page 37)). If the output voltage falls below 20 V, the device shuts down latching, the red LED lights up. This limit voltage of 20 V is independent of the set output voltage. The 'Short-time overload current' feature is not available in this operating mode. In order to also be able to charge large capacitances in this operating mode at the output, non-latching shutdown is performed during the first ten seconds after power on. During these first 10 s, the device responds for overload as if the switch is "OFF". Constant current: C Start delay 10 s Immediate start Delivery state "Hard" characteristic curve (see Figure 6-6 Output characteristic single operation (Page 36)) for normal operation (single operation): The output voltage is independent of the output current. Delivery state If the output current rises above the rated value and above the current limit, the device reduces the output voltage. The yellow LED lights up if the output voltage falls below 20 V. Delivery state Note Selector switches may only be activated when the device is switched off.

If this instruction is not observed, touching live parts can result in death or serious injury. 5.1 Line-side connection The SITOP PSU400M power supply is designed for connection to a 600 V DC link with an operating voltage range from 200 (300) - 900 V DC. Figure 5-1 Line-side connection The line supply is connected via terminals 600 V DC "+" and "-" and PE (see Figure 5-1 Lineside connection (Page 27)) and must be implemented according to IEC 60364, EN 50178 and EN 61800-5-1. A protective device (miniature circuit breaker or circuit breaker) and a disconnection unit for the power supply must be provided. The device is to be connected to the inverter in parallel after the DC disconnector. In other applications, a surge arrester and/or an EMC filter may have to be provided. NOTICE Hot plug in and hot plug out are not permissible! Maximum voltage rate of rise of the supply voltage: 1 V/s SITOP PSU400M Manual, 05.2018, C98130-A7601-A1-5-7629 27 Installation 5.1 Line-side connection Note Together with the 6EP1566-3AA00 ballast device to limit the voltage rise, hot plug-in and hot plug-out are permissible. A filter is integrated in the ballast to improve the EMC of power supply PSU400M (only applicable for product version 1). Note A short-circuit proof supply line must be provided at the input side. The breaking capacity of the internal fuse at input "+" and "-" is 20 kA; L/R < 2 ms. The protective conductor of the line supply must be connected at the PE terminal. The crosssection of the protective conductor cable must be the same as the supply cable. NOTICE Country-specific regulations must be observed when installing. When installed in wind power plants, the device should only be operated in LPZ2, in accordance with IEC 61400-24. SITOP PSU400M 28 Manual, 05.2018, C98130-A7601-A1-5-7629 Installation 5.2 Output-side connection 5.2 Output-side connection At its output, the SITOP PSU400M power supply provides an isolated PELV output voltage (Protected Extra Low Voltage). When connected to the converter DC link, the output must be grounded at one end. The ground connection should be established outside the device. Note The SITOP PSU400M power supply has two protective conductor connections (PE). It is not permissible that the protective conductor is connected to the input, not even capacitively. The cross-section of the protective conductor connections (PE) must be the same as the supply cable. The output is no-load, overload, and short-circuit proof. If an overload occurs, the electronic current limiting function limits the output current to a maximum value (see Section Technical data (Page 31)). Figure 5-2 Output-side connection The output voltage is connected via the + and - terminals at the output of the power supply (see Figure Output-side connection (Page 29)). Ensure that the output cables are dimensioned correctly for the maximum output current rms value and fused accordingly.

The following must be observed: The cables connected to each power supply at terminals "+" and "-" must have identical lengths and the same cable cross-sections (or the same impedance) up to a common external connection point (terminal strip) if possible. The power supplies connected in parallel must be switched on simultaneously with a common switch in the line feeder cable (e.g. with the main switch available in control cabinets). The output voltages measured in no-load operation for the power supplies that are not yet connected in parallel should not deviate more than a maximum of 50 mV. This usually corresponds to the factory setting. If the output voltage is changed, you should connect the "-" terminals and then, in no-load operation, measure the voltage difference between the "+" terminals that have not yet been connected. The voltage difference should not exceed 50 mV. Figure 9-1 Parallel connection SITOP PSU400M Manual, 05.2018, C98130-A7601-A1-5-7629 47 Applications 9.1 Parallel connection to increase the power rating NOTICE Protective circuit for the parallel connection of more than two power supplies When connecting more than two power supplies in parallel, additional measures must be taken to prevent high reverse currents in the event of a secondary device fault. For this purpose, a suitable protective circuit (e.g. decoupling diode or DC-capable circuit breaker) must be installed between each "+" terminal of the power supply and the common connection point. SITOP PSU400M 48 Manual, 05.2018, C98130-A7601-A1-5-7629 Applications 9.2 Parallel connection for redundancy 9.2 Parallel connection for redundancy Connecting several 24 V power supplies in parallel for redundancy purposes is required if especially high demands are placed regarding the availability of a reliable 24 V power supply. Using the SITOP PSE202U redundancy module, two power supplies of the same type up to 20 A can be decoupled (Figure 9-2 Redundant configuration with two power supplies and SITOP PSE202U redundancy module (Page 49)). When one of the devices fails, then the other automatically takes over the power supply. If one of the power supplies fails, then this is signaled using an LED on the redundancy module as well as an isolated relay contact. When dimensioning the system, it must be ensured that n+1 redundant connected power supplies can handle the total power requirement of the remaining n power supplies. Note For a high reliability of the supply, it is recommended that the redundant switched power supplies are fused separately on the line-side and, if possible, be connected to different line supplies. Figure 9-2 Redundant configuration with two power supplies and SITOP PSE202U redundancy module You can find additional information at: SITOP PSE202U manual (https://support.industry.siemens.com/cs/ww/en/view/42248598) SITOP PSU400M Manual, 05.2018, C98130-A7601-A1-5-7629 49 Applications 9.3 Series connection for increased voltage 9.3 Series connection for increased voltage To achieve an output voltage of 48 V DC, two 24 V SITOP power supplies of the same type can be connected in series. Depending on the grounding point of the secondary output voltages, voltages of +48 V, 24 V or -48 V can be realized. Note For additional details, see Catalog KT 10.1 Chapter 15 Technical information and configuring (see http://w3app.siemens.com/mcms/infocenter/content/en/Pages/order_form.aspx?nodeKey=ke y_518431&infotype=catalogs)). WARNING SELV is not guaranteed in the case of a fault When connecting two power supplies in series, the continuous, permissible SELV voltage of a maximum of 60 VDC according to EN 60950-1 cannot be guaranteed in the case of a fault. Figure 9-3 Series connection SITOP PSU400M 50 Manual, 05.2018, C98130-A7601-A1-5-7629 Applications 9.4 Overload protection in the 24 V output circuit 9.4 Overload protection in the 24 V output circuit If an overload occurs, the electronic current limiting function of the 24 V power supply limits the output current to a maximum value (see Section Technical data (Page 31)). The output cables are protected against a thermal overload if they are dimensioned corresponding to the maximum rms output current, or protected using additional components (for example, miniature circuit breaker, fuses). However, a load circuit that fails as a result of overload, for instance, should frequently be reliably and quickly identified and specifically switched off before the power supply goes into current-limiting mode (in current-limiting mode, the supply voltage would also be reduced for all of the remaining 24 V loads). The SITOP PSE200U selectivity module with 4 outputs (versions with adjustable output current range for each output from 0.5 - 3 A and 3 - 10 A) is available for this purpose; this monitors the 24 V branches for overload and short circuit (Figure 9-4 Electronic protection of 24 V loads using the SITOP PSE200U selectivity module (Page 51)). Brief current peaks, e.g. as a result of a high inrush current, are permitted, and branches with a longer overload are switched into a no-current condition. This is also ensured for cables in a high-ohmic condition and for short circuits that slowly develop over time. When an output fails, the fault is signaled using a group signal contact or as a single channel signal, and the branch of the module involved is displayed using an LED. For variants with single-channel signaling, function blocks for evaluation purposes are available for SIMATIC S7-1200/1500/300/400, for STEP 7 Classic and TIA Portal at no charge.

The SITOP power supply product portfolio includes various DC-UPS solutions to prevent the failure of the 24 V power supply voltage. Power supply failures up into the minutes range can be buffered using the maintenance-free SITOP UPS500 DC-UPS modules based on capacitors (Figure 9-5 24 V buffering to allow the saving of process data and controlled shutdown of PCs (Page 52)). Figure 9-5 24 V buffering to allow the saving of process data and controlled shutdown of PCs Using the free-of-charge SITOP DC-UPS software tool, DC-UPS systems can be simply integrated into PC-based automation solutions.
