● Important Safety Instructions

When using the product, please read follow information below to avoid fire, lightning or other

personal injury:

● Before using the Series inverter, read all instructions and cautionary markings on the

Series inverter, and all appropriate sections of this guide.

●Use only a accesories recommended or sold by , otherwise may result in risk of fire, electric shock,

or injury to persons.

● To avoid risk of fire and electric shock, make sure that existing wiring is in good condition and

cables used are not undersized. Do not operate the Series inverter with damaged or substandard

wiring.

● Do not disassemble the S eries inverter. It contains no user-serviceable parts. See Warranty

for instructions on obtaining service. Attempting to service the Series inverter, the user may result

in risk of electric shock or fire and will void the warranty.

● To reduce the risk of electric shock, authorized service personnel must disconnect both AC and DC

power from the Series inverter before attempting any maintenance or cleaning or working on any

circuits connected to the Series inverter. Turning off controls alone will not reduce this risk.

● Keep away from flammable, explosive materials to avoid fire disaster.

● The installation location should not be close to humid or corrosive substance.

● To avoid electric shock, please do not disassemble the inverter as there are high-voltage

capacitances installed inside the inverter. Fatal High-voltage will remain in the inverter for 5 minutes

after its disconnection from grid or PV plant.

● To reduce the chance of short-circuits, authorized service personnel must use insulated tools when

installing or working with this equipment.
