Panasonic Eco Solutions Nordic ABMEW01623 Rev: - EBL128 Operating Instructions V2.0.x7119 Commissioning an EBL128Before you connect any power to EBL128 all other cableconnections shall be made. Check, once more, that the connectionsare correct.A tip! Measure the resistance of each loop wire (L & C respectively)before turning on the power. Check that the L-wire (SA) that goes outon terminal J1:1 comes back at terminal J1:3 and so on. If the loophas short circuit isolators, only the C-wire (SB) can be measured.Also measure the resistance between the loop wires and 24V, 0V andEarth (J2:1, 2 and 3). The resistance should be very high (mega ohm).1. Remove the rectifier (power supply) fuse (F1) on the main board.2. Remove the battery fuse (F2) on the main board (or the fusebetween the batteries).3. Connect the batteries to the main board.4. Connect the rectifier to the mains (230 V AC).5. Put back the rectifier fuse (F1) on the main board.586. Put back the battery fuse.7. LED "Operation" (L6) lit indicates that the 24 V DC power supply(rectifier and/or battery) is okay.8. An automatic restart will now take place (see chapter "Restart",page 77.9. The site specific data (SSD) is now to be downloaded, see chapter"SSD programming & download", page 72.See also chapter "Calibration of supervised outputs (H5/A1)", page112.58 Regarding especially the previous main board 4556 (P.c.b. No.9285-5A): If a lot of units (especially units with high internalcapacitance) are connected to EBL128, the total momentary inrushcurrent consumption might activate the electronic short circuitprotection and EBL128 will not start working. In such a case, putback the battery fuse before the rectifier fuse (i.e. the batteries have tobe reasonably charged) or temporarily disconnect some of the units inorder to reduce the current consumption while EBL128 is powered.
