For alternative solutions please consult Nilar AB.See also Appendix for circuit diagram.6.5.1 Order of Battery packsDuring manufacturing the battery packs are matched,sorted and labelled in order to achieve the bestperformance of the battery string.Sort the battery packs according to the labels from rightto left, where the first battery pack in a battery string isdesignated as ‘A’, the second battery pack is designatedas ‘B’ etc.For further information regarding ID-marking and system structuring,please contact your local Nilar representative.Figure 40: Battery string sorted according to labeling, from right to left6.5.2 Removal of cover lidRemove the cover lid of the IMU by loosening the two(2) torx screws size 20 with a screwdriver for all thebattery packs (see section 6.4.1).Figure 41: Battery string with IMU cover lids removed6.5.3 Installation of current sensor cableConnect the cable for the current sensor cable into thedesignated connection socket on the IMU (see section6.4.2) of battery pack ‘A’.Indicated as light blue (●) in the following figure.Figure 42: Installation of current sensor cable on battery pack ‘A’6.5.4 Series connection of CANopen communicationcableCANopen is a series bus which must have a terminationof 120Ω at each end. Make sure that a terminationresistor 120Ω is installed between the external batterymanagement system and the ingoing CANopencommunication that connects to battery pack ‘A’.Connect the ingoing CANopen communication cablewith its RJ45 plug into the CAN2 socket of battery pack‘A’ (see section 6.4.3).Connect the interpack CANopen communication cablewith its RJ45 plug into the CAN1 socket of battery pack‘A’ (see section 6.4.3). Connect the other side of thecable into the CAN2 socket of battery pack ‘B’.Connect the other side of the cable into the CAN2socket of battery pack ‘B’.Indicated as green (●) in the following figure.Installation altitude of a batterypack string configuration may notexceed 2000 meters above sea levelfor a 800 VDC system.CAUTION! |
