2 Installation Instructions
2.1 General installation notes
•
Read all the installation instructions carefully in the manual before installation.
Be very careful when installing the batteries. Please wear eye protection when installing the open-type
•
lead-acid battery, and rinse with clean water in time for battery acid contact.
Keep the battery away from any metal objects, which may cause a short circuit of the battery.
•
•
Acid gas may be generated when the battery is charged. Ensure that the surrounding environment is well
ventilated.
•
The inverter/charger requires enough clearance above and below for proper airflow. Do not install the
inverter/charger and the lead-acid liquid battery in the same cabinet to avoid the batteries' acid gas from
corroding the inverter/charger.
•
Only charge the batteries within the control range of this inverter/charger.
Loose power connections and corroded wires may result in high heat that can melt wire insulation, burn
•
surrounding materials, or even cause a fire. Ensure tight connections and secure cables with clamps to
prevent them from swaying while moving the inverter/charger.
Select the system cables according to the current density of not more than 3.5A/mm
•
National Electrical Code Article 690 NFPA70.)
Avoid direct sunlight and rain infiltration when installing it outdoor.
•
•
After turn off the power switch, there is still high voltage inside the inverter/charger. Therefore, do not open
or touch the internal components and perform related operations after the capacitor's total discharge.
•
Do not install the inverter/charger in a harsh environment such as humid, greasy, flammable, explosive, or
dust accumulation.
•
The DC input terminal is equipped with reverse polarity protection. Therefore, the reverse connection of the
DC input terminal will not cause fatal damage to the product. However, it is strongly recommended to
connect the inverter/charger with the PV array and utility after normal running.
•
Both utility input and AC output are of high voltage, do not touch the wiring connection to avoid electric
shock.
To prevent injury, do not touch the fan while it is working.
