5.1 Installation Notes
⑴ This charge controller must only be used in PV systems by 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 referred to herein.
⑵PV-modules must always be disconnected prior to the installation and adjustments of the charge
controller; Make sure the circuit breaker, fuse or disconnects of the battery terminal are turned off.
⑶ Double check whether battery voltage meets the voltage range of the 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 provoking any sparks, using fire or any exposed flame
close to any batteries, ever. 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 by all means. Have fresh water
available to immediately wash and clean any contact with battery acid. Get immediate medical aid in case
of any hazard that may occur. Never install/handle with 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 any water, ever, 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, and eliminate any electrical
loose connections to eliminate by all means any hot electrical connection spots.
CAUTION: Please read all instructions and precautions in the manual before proceeding
with the installation! It is recommended to remove the protective film cover from the
LCD screen before operation.
5.2 Mounting Location Requirements
Do not subject the PV charge controller to direct sunlight or any other heat sources. Protect the PV charge
controller from any dust, dirt and moisture. Mount it flat to a vertical wall. Must be a non-flammable
material. Maintain a minimum clearance of 15 cm below and around the controller to ensure unhindered
air circulation. Mount the PV charge controller not too far from the batteries (for accurate voltage sensing
least lessening).
Mark the position of the PV charge controller fastening holes on the wall, drill 4 holes and insert dowels,
fasten the PV charge controller to the wall with the cable openings facing downwards.
