6 Electrical Connection
6.1 Safety during Electrical Connection
Danger to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous DC voltage, which is present in the
DC conductors and the live components of the inverter. Touching the DC conductors or the live
components can lead to lethal electric shocks. If you disconnect the DC connectors from the
inverter under load, an electric arc may occur leading to electric shock and burns.
• Do not touch non-insulated cable ends.
• Do not touch the DC conductors.
• Do not touch any live components of the inverter.
• Have the inverter mounted, installed and commissioned only by qualified persons with the
appropriate skills.
• If an error occurs, have it rectified by qualified persons only.
• Prior to performing any work on the inverter, disconnect it from all voltage sources as
described in this document.
Damage to seals on the enclosure lids in subfreezing conditions
If you open the enclosure lid when temperatures are below freezing, the enclosure lid seal could
be damaged. This can lead to moisture entering the inverter.
• Only open the enclosure lid if the ambient temperature is not below -5°C
• If a layer of ice has formed on the seal of the lid when temperatures are below freezing,
remove it prior to opening the enclosure lid (e.g. by melting the ice with warm air). Observe
the applicable safety regulations.
Damage to the inverter due to electrostatic discharge
Touching electronic components can cause damage to or destroy the inverter through
electrostatic discharge.
• Ground yourself before touching any component.
