| Others | The LVD shall be connected between the battery/charger connection point and the load. The LVD shall disconnect the load from the battery and the rectifier if the battery voltage reached the predetermined end of discharge limit. The LVD shall automatically reconnect the load when the battery voltage recovers to an acceptable level. The LVD shall operate as follows: § Low voltage disconnect: -43.2 VDC (default) § Reconnect voltage: -48.0 VDC (default) § Voltage drops shall be considered in setting the above parameters. The LVD contactor used shall have an indication that permits visual verification of the contact position whether open or closed. |
