Connecting external batteries

Make sure there is a battery circuit breaker between the UPS and the battery module. Before connecting the battery module and the UPS, the circuit breaker must be turned OFF. Make sure the number of batteries in the battery module is appropriate for the amount for which the UPS has been configured. The standard quantity of 12 V batteries for the UPS is 20.  Connect one end of the battery cable to the appropriate socket on the rear panel of the UPS, the other end to the socket located on the battery module. In the case of more battery modules, the remaining connections are made between the supplied battery modules as in the figure below.

If it is necessary to extend the autonomy time, the power supply has the option of connecting a battery with a much larger capacity, thanks to the fact that it is equipped with an adjustable Charger with a capacity of 4A. Changes to the settings of the maximum battery charging current are made by an authorized service of the PSU manufacturer. When using larger capacity external batteries, placed on racks or in cabinets, special attention should be paid to the installation of an additional disconnector in the battery circuit, the correct polarity of the cables connected to the UPS battery and the number of batteries used. Incorrect connection of the “+” and “-” wires or connection of the wrong number of batteries may cause permanent damage to the UPS and the batteries.

Connecting the power supply and receivers
The CORE 6K and 10K UPS is designed for permanent connection through the terminal block located on the back of the UPS, as shown in the figure below.

UPS adapted for installation in a single-phase, three-wire installation, TN with a grounded neutral. The UPS should be connected to a separate electrical installation, made in accordance with the manufacturer’s Installation Recommendations. Installation should be carried out in accordance with the regulations and rules in force in a given country. The UPS power supply circuit should be protected with a circuit breaker or a fuse with the trip current value required in the recommendations. It is not recommended to use residual current devices in the UPS input.  Cables should be connected and arranged in such a way that no one can accidentally disconnect them.

Connection of remote EPO switch
The UPS is equipped with an EPO port for connecting a remote emergency stop switch. / REPO (Remote Emergency Power Off). By default, the EPO port is configured EPO as NC (normally closed), activation of EPO takes place by breaking the connection between Pin 1 and Pin 2 (removal of the jumper). It is possible to change the EPO configuration to NO (normally open) – contact an authorized service center. Changing the configuration to NO causes the need to remove the jumper between Pin 1 and Pin 2.

Control connector of the external EMBS service bypass
The EMBS connector is used to connect the auxiliary contacts of the External Maintenance Bypass switch to ensure that the UPS inverter is shut down when the External Bypass is turned on.
The EMBS connector is NO (normally open) type. A short circuit (between Pin 1 and Pin 2) causes the inverter to shut down.

Connection of communication options
The UPS has three communication ports:

To enable automatic management and monitoring of the UPS, connect the USB cable supplied with the device, on one side to the USB socket on the UPS and on the other side to the USB socket on the computer. The software provided with the UPS allows you to automate the processes of switching on and off the receivers connected to the UPS depending on the events that occur on the UPS (e.g. power failure, low battery level). The software also allows for ongoing monitoring and logging of UPS event history. RS232 and USB ports cannot be used simultaneously. The UPS also has an INTELLIGENT SLOT for additional cards, allowing for the use of communication options. Additionally, you can connect to the device:

• LAN card – allowing communication via LAN / WAN with the use of e.g. protocols: WWW, SNMP, Modbus TCP,
• AS-400 relay contact card for communication with external supervision systems, e.g. BMS, alarm control units,
