6 Electrical Connection
6.1 Safety during Electrical Connection
Electric Shock
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.
• Do not touch the DC conductors.
• Do not touch any live components of the inverter.
• Prior to performing any work on the inverter, disconnect it from all voltage sources as described
in this document (see Section 9).
Electrostatic discharge
Touching electronic components can cause damage to or destroy the inverter through electrostatic
discharge.
• Earth yourself before touching any components.
