Page 4: Important Notes
 9dot will not be liable for eventual damage or injury involving its hardware if it is used in any way inconsistent with its intended purpose, or if it is installed or used in an untested manner or is improperly maintained.
Page 5: Safety
Certifications and compliances The NCore (base unit and modules) has been tested and found to comply with CE and IC standards. It also complies with RoHS regulations and Part 15 of the FCC rules - this device may not cause harmful interference and must accept any interference received.
Page 6: General Description
This module allows you to charge lead or lithium batteries. It acts as a backup power source in the event of a power outage, as current flow goes both ways from the NCore (it will charge the batteries or draw current from them if necessary).
Page 7: Base Unit
It consists of digital inputs/outputs and integrated relays, to which the “Event Management” function can be associated. GROUNDING Grounding connector to protect people and equipment. FAN COOLERS The slots indicate the presence of a fan inside the NCore to facilitate heat dissipation. In total it has 4 fan coolers. NCORE MANUAL VER. 2 REV. 1...
Page 8: Modules
The outputs are isolated from the input rail and other modules, but not from each other. Special case -48V There are installations that require a -48V power supply, this option is perfectly feasible with NCore. We simply have to choose an isolated ADJ module with the following product code: NCORE-OUT-ADJ In this module it will be possible to select, via software, an output voltage of 48V for all the ports.
Page 9 GPIO is a hardware interface that allows microprocessors to interact with another external device. This pin group is controlled by the NCore device software. All pins share the same power supply, so pay attention to possible polarity / ground reference conflicts.
Page 10: Battery Management Module
This sensor is supplied with the battery management module. A longer thermistor can be connected. We just have to make sure that the thermistor is compatible with the NCore curve (10 KOhm, Beta coefficient 3380, NTC thermistor).
Page 11: Cmd Control Module
Start button As can be seen in the image, the NCore is equipped with a small start button (START) that is used only when it is necessary for the NCore to be started by the battery management module, that is, without the use of the power supply modules.
Page 12: Acdc Power Supply
As we can see, on the label we will find the product code: NCORE-CMD, the user's credentials and the default IP number, the serial number that will also be used to detect the SSID signal of the Wi-Fi and the ID of the software that is a unique identification of the device.
Page 13: Dcdc Power Supply
A hybrid ACDC and DCDC power supply is also possible: when the ACDC is at maximum load, the DCDC kicks in to compensate for the additional current required. ATTENTION: If the power of the photovoltaic panel, the battery or the micro-grid are insufficient to power the loads, the DCDC power supply module goes into protection. NCORE MANUAL VER. 2 REV. 1...

Page 18: Battery Voltage
Table 1 – Practical cases on types of batteries that can or cannot be connected to the NCore As shown in the table above, options 3 and 4 should not be connected to the NCore, as their maximum charge voltage is less than the maximum voltage value of the battery management module.
Page 19: Nominal Output Current
The NCore allows the battery to discharge to and no more than 40V, to prevent over discharge and possible damage. The battery is considered valid up to the minimum voltage threshold, after which the battery power is turned off.
Page 20: Charging Time
[48] This is a first approximation of the available load. Once the battery is connected to the NCore, the discharge cycle can be started to find out the actually usable charge. Charging time The battery charging time depends on the type of battery, the nominal charge of the battery (considering a complete discharge) and the charging current.
Page 21: Mode Of Use
Priority NCore allows to feed up to 20 different loads, more or less fundamental for the system in which it will be placed. Each port is assigned a unique priority from 1 to 21: 1 corresponds to the highest priority, 21 to the lowest. There are 21 because even the battery management module has assignable priority, as does an exit output.
Page 22: Instant Online
Each module can be hot added and removed while plugged in, allowing continuous operation and ensuring maximum reliability and safety. Dual processor NCore is equipped with 2 processors. One is dedicated to monitoring and operating the hardware part, the other is used for front-end management. This division makes the system immune to external attacks. Priority loads Each port has its own priority index, if necessary, the system turns off the ports with low priority ensuring that the port of the Always On devices is switched on.
Page 23: Installation
 Then attach the chassis to the cabinet or to the wall. If you want to fix the NCore to the wall, you can rotate the fixing tabs 90 °, keeping it vertical as in the following figure. Figure 11 - NCore with fixing tabs at 90 °...

Table 4 – OPT push button funcitons (*) resets the user to the default settings, not the IP address. Led coding Base unit For the overall status of the NCore, consider the first 3 LEDs arranged vertically to the left of the front. Colour Description Green...
Page 25 In case of operation, the LED of the port 3 would be fixed, in the event that the port 3 was deactivated or in a fault condition the LED would flash. See the “Interface description” section NCORE MANUAL VER. 2 REV. 1...
Page 26 ATTENTION: In the event of an ACDC or battery failure and if the base unit remains on, all outputs are disabled and remain faulty (flashing red), until the intended power supply is restored. If the error persists, a full reboot of the NCore is required.
Page 27: Connect With Ncore
Figure 13 – Schema of connection to communicate with NCore by SSH, web and SNMP interfaces In addition, it can be connected directly from a computer to the RJ45 port of the NCore. The NCoreOS operating system performs all the functions of interaction with the user through the control panel accessible through the web interface.
Page 28: Command Line Interface
Command line interface The SSH interface allows you to control some accessible parameters of the NCore, configure communication, read error messages, update the software and force some of the actions listed in a later paragraph. Access To access from the terminal, type the following command line: ssh admin@<número IP>...

Page 30: Actions
 Change the output voltage value (^) The phrase "only if disabled" refers to the situation where we have physically disconnected a module from the NCore. In this case, the system detects an unusual situation (considering the fact that the module was connected at the beginning and now it is not connected anymore), then it issues a failure warning until the module is removed from the interface.
Page 31: Snmp Interface
MIB download. To verify the operation of the interface, you can run a walk snmp command from the SSH shell, using the NCore IP: snmpwalk -v 3 -l authNoPriv -u admin -a sha -A "password" -m ./genmib.mib <IP NCore> .1.3.6.1.4.1.48108 Note that the complete sentence must be copied as is, writing the IP number of the NCore where it says “<IP NCore>”.
Page 32: Web Interface
There are two ways to connect to the NCore CMD controller: Ethernet and Wi-Fi. For the Wi-Fi connection we must look for the SSID "NCore _#" generated by NCore itself. The # symbol indicates the serial number shown on the label attached to the device.
Page 33: Interface Description
Interface description The web interface has an intuitive design that allows full remote management of the NCore. It has a responsive design, to be able to adapt graphically and automatically to the device with which it is displayed. It also allows multisession so that multiple people can log in with the same credentials.
Page 34: Options Bar
We will describe each of the buttons in the bar below. Stop The Stop button deactivates all the NCore outputs and also the battery management module. After having pressed it, it will ask us if we are sure. For a more detailed description, go to the “Deactivation Procedure” section.
Page 35 Green: Informational Each message will have the time and date of the event stamped to facilitate diagnosis. IMPORTANT NOTE: To automatically synchronize the day and time of the log, the NCore must be connected to a network with Internet access.

Figure 26 - Function to create, delete or modify users Logs Logs records all the warning or error messages reported by the NCore with different colors according to priority (red, yellow and green) and with the date and time. When there are new notifications, a red number appears on the dashboard bell. From this same bell you can also access the same log more directly.
Page 46 From the Battery menu you can select the type of battery used to change the charge cycle management. You can also remove the battery. Figure 28 – Information about the battery connected to the NCore IMPORTANT NOTE: It is essential to select the correct type of battery so as not to accelerate the degradation of the accumulator.
Page 47: Acdc Input Module
OFF indication appears above the board indicating that the input rail of the power supply modules of the NCore are disconnected. To be true, the test must be performed with the battery fully charged and with the expected loads applied, otherwise the percentage of charge displayed will not be accurate.
