2. Safety Information
Strict adherence to all safety instructions is mandatory to prevent electric shock, fire, injury, or damage to the inverter. Only qualified and authorized personnel should perform installation and maintenance procedures.
DANGER!
- High voltages are present within the inverter. All work must be carried out by a qualified electrician.
- This appliance is not intended for use by children or persons with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction.
- Children should be supervised to ensure they do not play with the appliance.
CAUTION!
- Risk of burn injuries due to hot enclosure parts. During operation, the upper lid and body of the enclosure may become hot. Only touch the lower enclosure lid during operation.
- Possible damage to health as a result of radiation effects. Do not stay closer than 20 cm to the inverter for any length of time.
WARNING!
- Do not operate the inverter when the device is running abnormally.
- Risk of electric shock!
- Hazardous voltage will be present for up to 5 minutes after disconnection from the power supply.
- Ensure input DC voltage is below the maximum DC voltage specified. Overvoltage can cause permanent damage to the inverter and other losses, which are not covered by warranty.
- Authorized service personnel must disconnect both AC and DC power from the X1 series inverter before attempting any maintenance, cleaning, or work on connected circuits.
NOTE!
- Grounding the PV generator is essential. Comply with local requirements for grounding PV modules and the PV generator. Solax recommends connecting the generator frame and other electrically conductive surfaces to ensure continuous conduction and proper grounding for optimal system and personal protection.
General Safety Guidelines:
- Read this entire manual carefully before installation and operation. Keep it for future reference.
- Use only attachments recommended or sold by Solax. Using unapproved attachments may result in fire, electric shock, or injury.
- Ensure existing wiring is in good condition and appropriately sized.
- Do not disassemble any parts of the inverter not mentioned in the installation guide. It contains no user-serviceable parts. Attempting to service the inverter yourself will void the warranty and may result in electric shock or fire.
- Keep the inverter away from flammable or explosive materials.
- The installation location should be free from humidity and corrosive substances.
- Authorized service personnel must use insulated tools when installing or working with this equipment.
- PV modules must have an IEC 61730 Class A rating.
- Never touch both the positive and negative poles of the PV connecting device simultaneously.
- The unit contains capacitors that remain charged to a potentially lethal voltage even after the MAINS and PV supply have been disconnected. Always wait 5 minutes after switching off PV and Mains before unplugging DC and MAINS couplers.
- When accessing the internal circuit, wait 5 minutes for capacitors to discharge. Measure the voltage between UDC+ and UDC- terminals with a multi-meter (impedance at least 1Mohm) to confirm total discharge.
