If you hold the front cover, the inverter body may fall down to cause injuries! 3. Handle the controller with care; otherwise, it may be damaged! 4. Never use the inverter damaged or with some parts missing; otherwise, injuries may be caused! 5.
Do not touch components of the control system with your hands; otherwise static charge may be generated to cause damage to the inverter! 6. The inverter has undergone withstand voltage testing before delivery. Do not perform withstand voltage testing on your own; otherwise the inverter may be damaged! During installation: Warning Danger 1. Please install the controller on metal or other flame-retardant objects and keep it away from combustible materials; otherwise, a fire may be caused! 2. Do not loosen the fixing bolts of components, especially those with red marks! Warning 1.
The inverter shall not be installed in a place with conductive dust, corrosive gas, salt spray, oily dirt, condensation, vibration or direct exposure to sunlight! 2. Never allow wire connectors or screws to fall into the inverter; otherwise, the inverter may be damaged! 3. When the inverter is installed a relatively closed cabinet or space, pay attention to the installation gap to ensure the effects of heat dissipation. During wiring: Danger 1. Observe the instructions in this manual and make wiring done by professional electrical personnel; otherwise, electric shock may be caused! 2.
The inverter must be separated from the power supply by using a circuit breaker (it is recommended to use a circuit breaker of greater rated current that is the most approximate to twice the rated current of the inverter); otherwise, a fire may be caused! 3
