Safety Instructions
Wiring and Installation
1. It's recommended that the wiring is performed by a professional.
2. Wear personal protective equipment (including protective goggles and gloves) during wiring
and installation.
3. It’s recommended to complete wiring before starting the vehicle and turning on the charger.
4. Connect the fuse cable and the positive terminal of the input cable to a torque of 3 to 4 N*m.
Insufficient torque will lead to a loose connection and cable melting. A torque higher than 6
N*m will break the fuse.
5. Follow these steps when connecting the input cable:
• Connect the ring terminal of the fuse cable to the positive terminal on the vehicle starter
battery or RV house battery.
• Connect the other end of the fuse cable to the positive terminal of the input cable.
• Ground the negative terminal of the input cable to the chassis of the vehicle or directly to the
RV house battery's negative terminal (if you are connecting it to an RV).
• Connect the input cable to the vehicle battery port on the charger.
5. Make sure that the input cable, fuse cable, and output cable are connected firmly as loose
connections can cause cable melting.
6. Avoid reversing the polarity of the positive and negative connections when connecting the
input cable and the fuse cable to the vehicle starter battery or RV house battery.
7. When wiring, avoid high temperature, sharp, and friction-prone areas, and securely fasten the
cables to avoid cable wear or loose connections caused by cable movement.
8. Refer to the specifications of the vehicle starter battery or RV house battery and make sure
that its nominal voltage is 12V or 24V. Always observe the safety instructions of the battery
during use.
9. Do not use the charger with damaged or non-rechargeable batteries.
10. Power off the charger and disconnect it before changing the wiring each time.
11. Make sure the screws are tightened to the specified torque during installation (M5: 3 N*m;
ST5.5: 4 N*m; M6: 9 N*m).
12. CAUTION: To reduce the risk of fire, use only battery packs that include the battery
management system and all necessary protection for the battery pack integral to the pack.
