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
the 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.
