2.Safety instructions and waiver of liability
2.1 Safety
①The solar charge controller may only be used in PV systems in accordance with this user manual and the specifications of other modules manufacturers. No energy source other than a solar generator may be connected to the solar charge controller.
②Batteries store a large amount of energy, never short circuit a battery under all circumstances. We strongly recommend connecting a fuse directly to the battery to protect any short circuit at the battery wiring.
③Batteries can produce flammable gases. Avoid making sparks, using fire or any naked flame. Make sure that the battery room is ventilated.
④Avoid touching or short circuiting wires or terminals.
Be aware that the voltages on special terminals or wires can be as much as twice the battery voltage. Use isolated tools, stand on dry ground, and keep your hands dry.
⑤Keep children away from batteries and the charge controller.
2.2 Liability Exclusion
The manufacturer shall not be liable for damages, especially on the battery, caused by use other than as intended or as mentioned in this manual or if the recommendations of the battery manufacturer are neglected. The manufacturer shall not be liable if there has been service or repair carried out by any unauthorized person, unusual use, wrong installation, or bad system design.

③ ④ ① ② ⑤ ⑥
To avoid any voltage on the wires, first connect the wire to the controller, then to the battery, panel or load.
Make sure the wire length between battery and controller is as short as possible.
Recommended minimum wire size:
10A : 4mm²; 20A : 10.0mm²; 30/40A : 16.0mm².
Be aware that the positive terminals of Max-Spirit are connected together and therefore have the same electrical potential. If any grounding is required, always do this on the positive wires.
Connecting capacitive load may trigger short circuit protection.
!
Remark: If the device is used in a vehicle which has the battery negative on the chassis, loads connected to the controller must not have an electric connection to the car body, otherwise the Low Voltage disconnect and electronic fuse functions of the controller are short circuited.

Solar Charge Controller Max-Spirit User Manual
4.1 Mounting location requirements
Do not mount the solar charge controller outdoors or in wet rooms. Do not subject the solar charge controller to direct sunshine or other sources of heat. Protect the solar charge controller from dirt and moisture. Mount upright on the wall on a non-flammable substrate. Maintain a minimum clearance of 10cm below and around the device to ensure unhindered air circulation. Mount the solar charge controller as close as possible to the batteries.
4.2 Fastening the solar charge controller
Mark the position of the solar charge controller fastening holes on the wall, drill 4 holes and insert dowels, fasten the solar charge controller to the wall with the cable openings facing downwards.
4.3 Connection
We strongly recommend connecting a fuse directly to the battery to protect any short circuit at the battery wiring.
Solar PV modules create current whenever light strikes them. The current created varies with the light intensity, but even in the case of low levels of light, full voltage is given by the modules. So, protect the solar modules from incident light during installation. Never touch uninsulated cable ends, use only insulated tools, and make sure that the wire diameter is in accordance with the solar charge controller’s expected currents. Connections must always be made in the sequence described below.
1st step: Connect the battery
Connect the battery connection cable with the correct polarity to the middle pair of terminals on the solar charge controller (with the battery symbol). If the system is 12V, please make sure that the battery voltage is within 10V~16V, else if the system is 24V, the battery voltage should between 20V~30V. If the polarity is correct, the LED on the controller will begin to show.
2nd step: Connect the solar module
Ensure that the solar module is protected from incident light. Ensure that the solar module does not exceed the maximum permissible input current.
Connect the solar module connection cable to the correct pole of the left pair of terminals on the solar charge controller (with the solar module symbol).
3rd step: Connect loads
Connect the load cable to the correct pole of the right pair of terminals on the solar charge controller
(with the lamp symbol). To avoid any voltage on the wires, first connect the wire to the load, then to the controller.
4th step: Final work
Fasten all cables with strain relief in the direct vicinity of the solar charge controller (clearance of approx.10cm).
