2.3 Safety Precautions
Danger to life from electric shock due to high voltages in the inverter
High voltages that can cause fatal electric shocks are present in the live components of the inverter.
• All work on the inverter must be carried out by qualified persons only.
• Prior to performing any work on the inverter, disconnect the inverter on the AC and DC sides
(see inverter installation manual).
• Always operate the inverter with the enclosure lid closed.
Danger to life from electric shock due to damaged devices
Operating a damaged inverter can lead to hazardous situations that result in death or serious
injuries due to electric shock.
• Operate the inverter only if it is technically safe and in full working order.
• Check the inverter regularly for visible damage.
• Operate the inverter only if there is no visible damage.
Risk of burns from hot surfaces
The surface of the inverter can get very hot. Touching the surface can lead to burns.
• Do not touch hot surfaces.
• During operation, do not touch any parts other than the lower enclosure lid of the inverter.
• Observe the safety messages on the inverter.
