[. . . ] Remote shut down terminal X52 pins 1 and 2 are as factory default linked (X12 is open). When the loop on X52 is opened, the logic circuitry will immediately shut down the UPS output and open the battery breaker (F1). Note!

The pins must be shorted in order to keep the UPS running. The EPO shall not be galvanically connected to any mains connected circuits. Reinforced insulation to the mains is required. See also "Start-up after EPO" . If the use of normally open EPO operation is desired, the loop on X52 has to be retained and the normally open EPO switch connected to X12. Operation is as above. Relayoutputs The UPS incorporates a programmable relay output with potential free contacts at X57 for remote alarm indications. 30 VAC 1 A or 60 VDC 0, 2 A nominal values. Additional (4) relay outputs can be obtained with the XSlot compatible AS/400 Relay Module. For more information, see the section "Using relay outputs" . Warning! Therelaycontactsmustnotbedirectlyconnectedtomainsrelatedcircuits. In addition, an Environmental Monitoring Probe (EMP) can be requested from the UPS manufacturer to obtain humidity, temperature and two relay inputs. It is connected to the communication port of the Web/SNMP module as option. Figure13ConnectUPS-X SNMP/Web Module and Environmental Monitoring Probe (EMP). AS/400RelayModule(optional) The Relay Module provides potential free relay interface for AS/400 connected computers and industrial applications. The relay interface supports both 15-pin D-sub connector and terminal block connections up to four (4) potential free relays. The relay contacts are rated for 1 A, 30 Vac or 200 mA, 60 Vdc, and they have a galvanic isolation from the other circuits of the UPS unit. 1025358 Revision D UPS 20-40 kVA, 230/400 V 50/60 Hz output User's Guide 27 Figure14AS400 Relay Module. SingleSerialPortModule(optional) To establish communication between the UPS and a computer, connect your computer to the UPS communication port using the supplied communication cable. When the communication cable is installed, power management software can exchange data with the UPS. The software polls the UPS for detailed information on the status of the power environment. If a power emergency occurs, the software initiates the saving of all data and an orderly shutdown of the equipment. Modbus/JbusModule(optional) The Modbus module provides monitoring and integration to the Building Management Software (BMS) such as Wonderware. It features continuous and reliable communication through isolated DB9 ports (RS485/RS232) or a terminal strip (RS485).

It provides useful information about the unit itself, load status, events, measurements, and settings. The LCD backlight is switched on by pressing any button. [. . . ] Select: CONTROL -> GO TO NORMAL MODE. Verify the transfer by checking that the yellow bypass LED is turned off. Figure29. System bypass switch of the optional SPM Shut-downprocedure While system is running and UPSs are supporting load, there are two different ways to perform a shutdown. The user can select either to shutdown the whole system or only one UPS. Select TURN SYSTEM OFF from the main menu Õ All the UPSs in the system will go to stand-by mode. [. . . ]
