Safety Instructions
This chapter contains important safety and operating instructions. Read and keep this manual for future
reference.
Before using the inverter, please read the instructions and warning signs of the battery and correspond-
ing sections in the instruction manual.
Do not disassemble the inverter. If you need maintenance or repair, take it to a professional service
center.
Improper reassembly may result in electric shock or re.
To reduce the risk of electric shock, disconnect all wires before attempting any maintenance or cleaning.
Turning o the unit will not reduce this risk.
Never charge a frozen battery.
For optimum operation of this inverter, please follow the required specications to select the appropri-
ate cable size. It is very important to operate this inverter correctly.
Be very cautious when working with metal tools on or around batteries. Dropping a tool may cause a
spark or short circuit in batteries or other electrical parts, even causing an explosion.
Please strictly follow the installation procedure when you want to disconnect AC or DC terminals.
Please refer to this manual's "Installation" section for details.
Grounding instructions - this inverter should be connected to a permanent grounded wiring system. Be
sure to comply with local requirements and regulations to install this inverter.
Never cause AC output and DC input to short-circuit. Do not connect to the mains when DC input short
circuits.
Product Disposal
DO NOT dispose this product with domestic waste!
Electrical devices should be disposed of in accordance with regional directives on electronic and/ or elec-
tronic-waste disposal. In case of further questions, please consult your supplier. In some cases, the supplier
can take care of proper disposal.
WARNING
HIGH LIFE RISK DUE TO FIRE OR ELECTROCUTION.
Sunsynk Single-Phase Hybrid Inverter can only be installed by a qualied licensed electrical
contractor. This is not a DIY product.
