Precautions
Installation & safety instructions
- The converter must be mounted on solid metal, aluminum for heat dissipation. The converter will be very hot during use, keep wiring from touching the converter and or do not touch it !
- Confirm battery pack main positive and negetive potentials !
- For older cars using a negative through key switch you must use a relay for converter activation. Consult technical services for this application. For radio memory you must either leave the key switch in the on position or hardwire the yellow and red wire to 36/48/60/72 volt positive. Doing this you will have a constant drain on the battery pack and long extended period of “setting” will help drain the battery pack. It is advised for long storage to disconnect the converter.
- Anytime a battery pack is disconnected manufacturers instructions must be followed. Always make sure if the car has a run/tow switch the switch is placed in the tow position before disconnecting anything. Torque battery cable nuts to 80 to 100 inch pounds. Spray coat connections with anti corrosion spray. Tech Note: loose connection create heat and arcing make sure all wiring connections are clean and tight.
- Make sure all wiring is free from moving parts, sharp objects or extreme hot area’s! Tie up any loose wiring
- use process equipment will pay attention to timely remove surface dust and other debris impact of heat dissipations .
- Please don’t disassemble the DC-DC converter yourself . it may cause electric shock or other injuries .
- In order to avoid damaging the power cord , don’t put any object on the line and place the line where it will not be stepped on . If the cord is frayed or damaged , replace it immediately
