Please provide information about the operating system, the type and amount of PC’s beingused.6.6 Temperature compensationWith this option the charging voltage for the battery can be regulated by means of the temperature. A sensor is placedadjacent to the battery and connected to the rectifier of the UPS. The battery charging voltage gets reduced about –1mV/°C per cell, e.g. a Ups with a 192 cell battery will therefore reduce the charging voltage of about -192mV/°C. Theminus sign indicates the declination of the battery charging voltage at rising temperature.The interconnection of the temperature sensor is shown in diagram X0013800.VP3 in annex.6.7 MODBUS-AdapterThe application of the Modbus-Adapter is described in the operating manual BAX 2408.6.8 Manual Bypass for JST hp E 400-800 kVAThe manual Bypass (MBCB) is only available as an Option and is housed in an external cabinet.
