text: <s>[INST] 1336E BRF 20 AN impact drive , open frame Summary: Input DC voltage application Hi all. This drive according to its catalog number can use input voltages of 380-480V AC or 513-612V DC. Does anybody have experience with this DC option, is this for the brake only or it could supplement the 3 phase AC input ?If so,how to hook it up ? THANKS! [/INST] I'm not an expert, but as far as I can see from the User Manual, the only DC bus terminals on that frame of drive are for Dynamic Brake Option. - fuzzy logic Please remember to Rate the Comments( ) to enhance the reputation of the User who provided help,or close your Topic using the ( ) button over the answer that solved it.
