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
air-flow. 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

(according to 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.
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. 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.
