Danger to life from electric shocks due to live voltage
Do not open the enclosure at any time. Unauthorized opening will void warranty and warranty claims and in most cases terminate the operating license.
- When the enclosure lid is removed, live components can be touched which can result in death or serious injury due to electric shock.
Lethal danger from electric shock due to possibly damaged inverter
- Only operate the inverter when it is technically faultless and in a safe state.
- Operating a damaged inverter can lead to hazardous situations that can result in death or serious injuries due to electric shock.
WARNING
Risk of inverter damage or personal injury
- Do not connect or disconnect the PV and AC connectors when the inverter is running.
- Wait at least 10 minutes for the internal capacitors to discharge after all electric devices are removed and the inverter is powered off.
- Ensure that there is no voltage or current before connecting or disconnecting the PV and AC connectors.
WARNING
All the warning labels and nameplate on the inverter body:
- must be clearly visible; and
- must not be removed, covered or pasted.
CAUTION
Risk of burns due to hot components!
Do not touch any hot parts (such as the heat sinks) during operation. Only the DC switch can safely be touched at any time.
NOTICE
Only qualified personnel can perform the country setting. Unauthorized alteration may cause a breach of the type-certificat. marking.
Risk of inverter damage due to electrostatic discharge (ESD)!
By touching the electronic components, you may damage the inverter. For inverter handling, be sure to:
