Battery Supply Connections	Required Contactor Sequencing
Figure 5. Example Battery Supply Connection The image shows an example Battery power supply connection to the drive that provides a supply voltage during rescue operation.	The Rescue Supply Contactor must only be closed when the Main Contactor is open. A delay time of no less than 2 seconds must be included when changing over to/from Rescue supply to/from mains supply mode. The Main Supply Contactor and Rescue Supply Contactor must be interlocked so that both cannot be energised at the same time, failure to do so may result in damage to the battery/contactor. The Battery must have a reverse power protection diode fitted as shown in the diagram opposite. The protection diode must have a voltage rating of at least 1000V and with a current rating of 2 x drive rated current. The drive will always wait until the next stop command (Direction input removal) before rescue mode operation is activated and likewise when rescue mode is de-activated the drive will wait until the next stop command before changing back to normal mains supply operation. Warning A suitable protection diode must be fitted to the battery supply as shown in the example to prevent damage to the system. Suitable protection must be provided for all wiring.
