Figure.4.2-1 Figure.4.2-2 Climatization Ventilation Direction of ventilation is front/sides to back. The room should be equipped with ventilation system or air conditioning to collect warm air from the top of the room and provide cool air at the bottom. Figure.4.
In order to profit from optimal ventilation, the side panels must remain in place for UPS with internal battery. The UPS should be mounted on a concrete surface and non-combustible surface. 4.3. Storage Please store the UPS in an environment where the temperature is between -25°C + 55°C, no receipt of direct sunlight, far from the heating, in a dry place. Environmental humidity must be between 20-95% (non-condensing).

5. INSTALLATION When the UPS is delivered, examine the packaging and product carefully to see if any damage occured during transport. If either possible or ascertained damage is found report it immediately to: • the carrier; • LEGRAND Technical Assistance Center. Make sure that the unit received corresponds to the material specified on the delivery document. The UPS Keor T packaging protects the equipment against mechanical and environmental damages.
5.2. Unpacking Procedure Figure.5.2-1 Remove the wrap and the package. Figure.5.2-2 Figure.5.2-3 Place UPS in the installation area.
Figure.5.2-4 Remove the side parts which prevent the transpallet to damage the UPS. Unload the UPS from the pallet. It is recommended to store the original UPS packaging for future needs. 5.3. Installation Procedures and Instructions The equipment may only be installed and commissioned by authorized LEGRAND UPS Technical Service Staff or authorized LEGRAND distributor Technical Service Staff. When the UPS is brought from a cold place to a warmer place, humidity of the air may condensate in it.
5.3.1. Power Connections Make sure that all circuit breakers are “OFF” before starting with the installation. The power screw terminals are located on the lower front side of the UPS. Firstly, open the UPS door, screw out of the metal cover, afterwards open plastic cover of terminals. After the covers are removed, the cables shall be passed through the hole under the terminals. After all connections done, replace the covers in order. Figure.5.3.1-1 Figure.5.3.1-2 Figure.5.3.

Connections shall be made in the following order; 5.3.1.1. Earth Connection The device shall be earthed for a safe and reliable operation. Connect the PE/PB ground terminals before connecting any other cable. Figure.5.3.1.1-1 Input Mains Supply’s Protective Earth terminal PE of the UPS shall be connected to the ground with a low impedance connection.
Please add three-pole (3-pole) MCCB to distribution panel for UPS’s input. Do not connect any other load to it. Connect the phase cables to X1 MAINS SUPPLY: X1/L1 - X1/L2 - X1/L3 terminals, the neutral to X1 MAINS SUPPLY: X1/N terminal. Neutral connection should be done directly from distribution neutral bus to UPS neutral. If auxiliary supply exists, remove all bridges. When used, the residual current earth leakage protection system must be common for the two AC inputs and installed upstream.
Please add three-pole (3-pole) MCCB to distribution panel for UPS’s auxiliary input. If auxiliary supply exists, remove all bridges. Connect the phase cables to X4 AUXILIARY SUPPLY: X4/L1 - X4/L2 - X4/L3 terminals, the neutral to X4 AUXILIARY SUPPLY: X4/N terminal. Neutral connection should be done directly from distribution neutral bus to UPS neutral. 5.3.1.4. Battery Connection You may find more information about Keor T Models and Battery capacity in Section 5.1. Models and Dimensions.

8. COMMUNICATION Interface connectivity cards allow UPS to communicate in a variety of networking environments and with different type of devices. Standard and optional communication interfaces are listed below; Communication Interfaces Model (kVA) 10 15 20 30 RS232 • RS485 / MODBUS • Dry Contacts • Generator Interface • Remote Emergency Switching Device (ESD) Interface • Internal SNMP / Web Monitoring / e-mail ◦ 40 60 ◦ External SNMP • Standard ◦ Option Tablo.7 1. 2. 3. 4. 5.
Communication Cable Path Figure.8-2 8.1. Serial Communication (RS232) UPS is equipped with Serial Communication as standard. RS232 cable shall be shielded and shorter than 25m. RS232: DSUB-9 male connector with the following pin layout shall be used on the UPS side of the connection cable. RS232 PIN LAYOUT PIN# Signal Name Signal Description 2 RX Receive Data 3 TX Transmit Data 5 GND Signal Ground Tablo.
Over SNMP communication, battery test can be started or current test can be cancelled. UPS can be shut-down or stand-by (stand-by duration is adjustable). Alarms can be discarded. If Serial Communication cable is needed, it can be produced according to the pin configuration described at side. 8.2. Internal SNMP Communication Internal SNMP card can be installed into SNMP slot placed at the front of UPS. As soon as SNMP installed, RS232 port would be disabled.
8.3. Emergency Switching Device and Generator Connections Voltage to be applied to the digital inputs is 5VDC. Maximum current drawn by each input is 1mA. 5VDC supply provided on the communication interface board can be used to supply both digital inputs. Figure.8.3-1 UPS output can be switched off immediately by Remote Emergency Switching Device interface (ESD) connection if desired. A remote latched switch can be used as described in above figure.
8.4. Dry Contacts 1 2 3 4 There are 4 dry contact sockets on the Interface Board. The relays can be programmable from Relay Functions menu (under Settings menu). “General alarm, Input failure, Battery failure, Output failure, Bypass active, Output overload, High temperature” alarms can be assigned to the contacts. Each alarm can be assigned to separate relays but also one alarm may be assigned to all relays.
8.5. RS485 RS485 with MODBUS protocol is used in a wide range of automation systems for Industrial Process monitoring or for Building Management Systems. This communication link allows monitoring UPS status and measurements with such systems. The RS485 differential line consists of three pins: • • • A is inverting pin (TxD-/RxD-) B is non-inverting pin (TxD+/RxD+) Middle Pin is reference pin (optional GND) Middle Pin is the reference potential used by the transceiver to measure the A and B voltages.

Appendix-2: Modbus List While reading data through MODBUS, the following addresses can be used. "03 - Read Holding Registers" must be selected to read the MODBUS data. We can send commands by using MODBUS. To do that function 06 – Write Single Register must be used. The data is defined as unsigned words (2 bytes).
Also we can use addresses 127 to get the UPS status. A decimal value will be received from address 127. If that value is converted to binary number, the UPS status can be read.
