In order to ensure safety, insulation of high voltage models (i.e. those with a nominal voltage of 500 V or higher, requires using only the two outer pins of the 4-pole terminal. The inner two pins, marked with NC (no connect), must remain unconnected. Page 13 mPower 300 Series (Rev G) -
Page 14: Ethernet Port
Therefore, only one interface should be used at any one time. However, monitoring is always available on any port at any time. Page 14 mPower 300 Series (Rev G) -
Page 15: Installation
After every transport, with or without packaging, or before commissioning, the equipment should be visually inspected for damage. An obviously damaged unit (e.g. loose parts inside, damage outside) must under no circumstances be put into service. Page 15 mPower 300 Series (Rev G) -

4.4.1 AC input connections Mains connection for an mPower 300 series system is done via the included mains cord. In case a different AC wiring is required, make sure that the other cable has a minimum cross section of 1.5 mm² (AWG 12). -
Page 18: Grounding Of The Dc Output
Grounding one of the DC output poles is allowed. Doing so can result in a potential shift of the grounded pole against GND. Because of insulation, there is a max. allowed potential shift of the DC output poles, which also depends on the unit model. See 8. Model Specifications Appendix. Page 18 mPower 300 Series (Rev G) -

• The Sense inputs must be connected with correct polarity to the load, means Sense+ to DC+ of the load etc., otherwise both systems may be damaged NC NC Output Share Sense Analog Interface Load Page 19 mPower 300 Series (Rev G) -
Page 20: Share Bus Connection
The analog interface is galvanically isolated from the unit internally. If not absolutely necessary, you should never not connect any ground of the analog interface (AGND) to the DC minus output as this will cancel the galvanic isolation. Page 20 mPower 300 Series (Rev G) -

In case the CDC drivers described above are not available on your system, or for some reason do not function correctly, commercial suppliers can help. Search the Internet for suppliers using the keywords “cdc driver windows“ or “cdc driver linux“ or “cdc driver macos“. Page 21 mPower 300 Series (Rev G) -

5.2.3.1 Power derating The mPower 300 series offer an extended AC supply voltage range, but are optimized for the use at 230 Vac, ±10%. Below a certain supply voltage, all models will automatically start to derate (i.e. reduce the maximum available output power). -
Page 25: Alarm Conditions
Switching off the unit by the mains switch can not be distinguished from a mains blackout and thus the unit will signal a PF alarm every time the unit is switched off. This can be ignored. Page 25 mPower 300 Series (Rev G) -
Page 26: Overtemperature
• the product of the output voltage and output current in the DC output reaches the adjusted OPP limit. This function serves to protect the connected load application so that this is not overloaded and possibly damaged due to an excessive power consumption. Page 26 mPower 300 Series (Rev G) -

Page 32: Adjustment Limits
Example: If you wish to set the limit for the current set value I-max to 90 A while the currently adjusted current set value is 100 A, then the set value first would have to be reduced to 90 A or less. The same applies vice versa when adjusting I-min. Page 32 mPower 300 Series (Rev G) -

Depending on your setting, the main display will change after leaving the setup menu and the right-hand rotary knob is then either assigned to set value of current or power Page 33 mPower 300 Series (Rev G) -

You can select the between view mode and the HMI lock, each with three button pushes. Attention! If you activate the HMI from within the quick menu, the additional PIN lock might become active, depending on your settings in the MENU. There is no extra indication here!

Page 35: Switching The Dc Output On Or Off
► How to remotely switch the DC output on or off via the digital interface See the external documentation Programming Guide if you are using custom software, or refer to the external docu- mentation of LabView VIs or other software, if available, provided by the manufacturer.

Page 36: Remote Control
The Ethernet interface typically requires network setup (manual or DHCP), but can also be used with its default parameters right from the start. 5.5.3.2 General For the network port installation refer to 3.2.5. Ethernet port. The digital interface require little or no setup for operation and can be directly used with their default configuration. All specific settings will be permanently stored, but could also be reset to defaults with the setup menu item “Reset”. Page 36 mPower 300 Series (Rev G) -
Page 37: Remote Control Via The Analog Interface
• Before the hardware is connected that will control the analog interface, it shall be checked that it can’t provide voltage to the pins higher than specified • Set value inputs, such as VSEL, CSEL and PSEL, must not be left unconnected (i.e. floating) • It is always required to provide all three set values at once. In case any of the set values is not used for adjustment, it can be tied to a defined level or connected to pin VREF (solder bridge or different), so it gives 100% Page 37 mPower 300 Series (Rev G) - Page 38 This can be done with pin REM-SB switching the DC output off and on again, means a HIGH-LOW-HIGH edge (min. 50ms for LOW), when using the default level setting for this pin. Page 38 mPower 300 Series (Rev G)
- Page 39 **** The error of a set value input adds to the general error of the related value on the DC output of the unit The accuracy of set values, as given in the table above, is only related to the input pin and adds to the general accuracy of the corresponding value on the DC output.

Unlock the HMI by pushing Enter within 5 seconds, otherwise the pop-up will disappear and the HMI remains locked. In case the HMI lock with PIN has been activated before, you are then requested to enter the correct PIN, otherwise the HMI will remain locked. Page 45 mPower 300 Series (Rev G) -
Page 46: Loading And Saving A User Profile
In the menu navigate to Profiles and push In the submenu (see figure to the right) select a user profile (1-5) to load and push again. In the screen you can now select View Profile n in order to check the stored settings and to decide, whether this profile is going to be loaded or not. Navigate to Load Profile n and confirm with to finally load the profile into the work profile. Page 46 mPower 300 Series (Rev G) -
Page 47: Parallel Operation In Share Bus Mode
The Share bus is wired from unit to unit ideally with an twisted pair of cables with non-critical cross section. We recommend to use 0.5 mm² to 1.0 mm². A maximum of 10 units can be connected via Share bus. The Share bus is poled. Take care for correct polarity of the wiring! Page 47 mPower 300 Series (Rev G) - Page 48 • If accidentally multiple or no units are defined as master the Share Bus parallel system cannot be initialised In situations where one or multiple units generate a hardware alarm like OV, PF or OT following applies: • Any alarm of a slave is indicated on the slave’s display only Page 48 mPower 300 Series (Rev G)

• an imminent problem with your unit can directly be solved, especially if we suggested to install an update during a sup- port case • a new feature has been added which you definitely want to use. In this case, the full responsibility is transferred to you. The following also applies in connection with firmware updates: • Simple changes in firmwares can have crucial effects on the application the units are use in. We thus recommend to study the list of changes in the firmware history very thoroughly. • Newly implemented features may require an updated documentation (Operating Guide and/or Programming Guide, as well as LabView VIs), which is often delivered only later, sometimes significantly later.

Page 51: Calibration (Readjustment)
6.3.1 Preface The mPower 300 series features a function to readjust the most important output values when doing a calibration and in case these values have moved out of tolerance. The readjustment is limited to compensate small differences of up to 1% or 2% of the max. - Page 52 Enter it using the right-hand rotary knob, just like would adjust a set value. Assure yourself the value is correct and submit with Repeat points 3. and 4. for the next three calibration steps (total of four steps). Page 52 mPower 300 Series (Rev G)
