WARNING
Risk of electric shock and 󹪝re from supply ne
tworks 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
󹪝re.
• Ensure that the prospective short-circuit current at the line terminal of the converter does
not exceed the breaking capacity (SCCR or Icc) of the protective device used.
WARNING
Electric shock if there is no ground connection
F
or missing or incorrectl
y 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.
WARNING
Electric shock due to connection to an unsuitable power supply
When
equipment is connect
ed 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- (Protective
Extra Low Voltage) output voltages for all connections and terminals of the electronics
modules.
WARNING
Electric shock due to damaged motors or devices
Improper handling of motor
s or devices can damage them.
Hazardous voltages can be present at the enclosure or at exposed components on damaged
motors or devices.
• Ensure compliance with the limit values speci󹪝ed in the technical data during transport,
storage and operation.
• Do not use any damaged motors or devices.
