Fundamental safety instructions

2.1 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.

WARNING

exceed the breaking capacity (SCCR or Icc) of the protective device used.
