Hello Gaston; From a note in the S7-400 module data manual, discussing the battery option on the power supply mdules (both AC and DC), it seems they recommend having the power supply installed and powered when installing thew batteries. See the attachment, taken from this link: SIMATIC S7-400 S7-400 Automation System Module Data Hope this helps, Daniel Chartier |
