    The yellow "Bat" LED lights up and the X2.2 – X2.1 "Bat" relay contact is made. They are accordingly supplied with backup power for the buffering time set via the DIP switches or until the maximum buffering time is up (deactivation after the exhaustive discharge threshold is reached). © Siemens AG, 2009 3/18...

    0.2C means: charging current = 0.2 x battery capacity x 1/h (i.e., in case of a 12Ah battery module, 0.2C is a charging current of 0.2 x 12Ah x 1/h = 2.4A) and so on © Siemens AG, 2009 16/18...

    4 hours. The point of intersection of the 21V horizontal lies above the time of 4 hours with "discharge characteristic 0.2C." Required battery capacity = 12A : 0.2 x 1/h = 60Ah; five 12Ah battery modules must thus be switched parallel. © Siemens AG, 2009 17/18...
