5.1 Installation Notes
⑴ This charge controller must only be used in PV systems in accordance with requirements given in this
user manual and the specifications of other system components provided by their manufacturers. No
energy source other than a PV generator may be connected to the PV charge controller.
⑵PV-modules must always be disconnected prior to the installation of the charge controller. Make sure
the circuit breaker, fuse or disconnects of battery terminal are turned off.
⑶ Double check whether battery voltage meets the voltage range of Charge Controller.
⑷Batteries store a large amount of energy, never short circuit a battery under any circumstances. We
strongly recommend connecting a protection fuse directly to the battery terminal for protection in case of
short circuiting the battery.
⑸Batteries can produce flammable gases. Avoid sparks, fire or any exposed flame close to any batteries.
Make sure that the battery room is well ventilated to disperse any gases.
⑹Only use insulated tools and avoid placing (any) metal objects near/close to batteries.
⑺Be extremely cautious when working with batteries. Wear eye protection. Have fresh water available to
immediately wash and clean any contact with battery acid. Get immediately medical aid in case of any
hazard that may occur. Never install/handle batteries alone.
⑻Avoid touching or short-circuiting wires or terminals. Be aware that voltages on given system
components, terminals or wires can be a multiple of battery voltage. Only use insulated tools, stand on dry
ground, and keep your hands always dry and protected by proper (approved) electrician gloves when
working on PV-Systems.
⑼Prevent moisture from penetrating the controller, outdoor installation must avoid any direct sunlight
and penetration of any water (e.g., rain) and humidity.
⑽After installation make sure that all connections are properly tightened, eliminate any loose electrical
connections.
