- Page 4 4.3 Reverse polarity protection: charger will not turn on if the battery pack is connected backwards (or less than 5V). 4.4 A switch on the charger marked “Override” is used to select either external or internal controlled charging. Override Off Use with EMS system, either CAN or digital input Override On Charger program based on pack voltage only (recommended for testing purposes only, do not use for normal charging).
- Page 5 5.2 Anderson SB50 Connector EMC Chargers with output greater than 10A come with an Anderson SB50 style connector for the output. These connectors are labeled “+” and “-”. A mating connector comes with the charger. 5.3 CAN and Digital Input Controls A five wire connector connects to the charger for interfacing with the BMS.
- Page 6 For a CAN communication connection connect the CANH, CANL and CAN GND to the matching connection on the CAN connection on the EMS CPU. The white connector may be cut off of the cable; however, note which wires are which before doing so.
- Page 7 If both the CAN communication and the digital inputs are connected CAN communications will take priority over the digital input for charge control. CAN communications requires the optional CAN board be installed on the EMS CPU.

6. Cautions Make sure charger voltage output matches to the number of cells in the battery pack. Make sure positive output of the chargers is connected to a positive connection to the battery pack, and the negative output of the charger is connected to a negative connection of the battery pack. - Page 9 unscrewing the cap with a #2 Philips screw driver. If the fuse is blown replace with an equivalent size fuse of the same voltage and amperage rating. If the charger finishes charging too early make sure that the connection from the charge to the battery pack is good and does not have high resistance.
