Fundamental safety instructions
1.1 General safety instructions
Risk of electric shock and fire from supply networks with an excessively low impedance
Excessively high short-circuit currents can lead to the protective devices not being able to
interrupt these short-circuit currents and being destroyed, and thus causing electric shock or
a fire.
● Ensure that the prospective short-circuit current at the line terminal of the inverter does not
Electric shock if there is no ground connection
For missing or incorrectly implemented protective conductor connection for devices with
protection class I, high voltages can be present at open, exposed parts, which when touched,
can result in death or severe injury.
● Ground the device in compliance with the applicable regulations.
Electric shock due to connection to an unsuitable power supply
When equipment is connected to an unsuitable power supply, exposed components may
carry a hazardous voltage. Contact with hazardous voltage can result in severe injury or death.
● Only use power supplies that provide SELV (Safety Extra Low Voltage) or PELV-
Electric shock due to equipment damage
Improper handling may cause damage to equipment. For damaged devices, hazardous
voltages can be present at the enclosure or at exposed components; if touched, this can result
in death or severe injury.
● Ensure compliance with the limit values specified in the technical data during transport,
● Do not use any damaged devices.
