Also, it is possible that same model on the market is produced with two production centers, however their partslist is the same. In such case, no alternative B.O.M. will be created. By looking at the third digit of t

2、he serial number, one can identify which B.O.M. is used for the set he is working with. If the third digit of the serial number contains the number “1” (example: KX1B033500001), then the set has been manufactured according to B.O.M. number 1. If the third digit is a “2” (example: KX2B0335000001), th

3、en the set has been produced according to B.O.M. no. 2. This is important for ordering the correct spare parts! For the third digit, the numbers 1.9 and the characters A.Z can be used, so in total: 9 plus 26= 35 different B.O.M.s can be indicated by the third digit of the serial number. Identificati

4、on: The bottom line of a type plate gives a 14-digit serial number. Digits 1 and 2 refer to the production centre (e.g. LM is Arts), digit 3 refers to the B.O.M. code, digit 4 refers to the Service version change code, digits 5 and 6 refer to the production year, and digits 7 and 8 refer to producti

Otherwise, it cannot be returned to the O.E.M. supplier for back charging! 2.3.7Practical Service Precautions It makes sense to avoid exposure to electric

While some may not be dangerous in themselves, they can cause unexpected reactions that are best avoide
