See here: https://cache.automation.siemens.com/dnl/zE0Mzk1MQAA_24523400_HB/420_OPI_24523400_en_1006.pdf Page 23, that graph is very clear, though I think you should check what you are connecting for the next time, check the voltages ratings, and you network properties, if your drive have exploded you should call technical support (and my guess are that you will have to pay cause it was you fault, you should have read carefully all the instructions and requirements). Good luck! |

dear hutdotedudotvn, As you said there is no siemens service centre near your place and also other service centres are closed for 2 days so i suggested you how to use the drive even w/o the varistors. In any case you will not get any warranty from siemens when they find the varistor defective. For you no problem as there is no warranty issue. I hope i was of help to you. diwa |
