WARNING
Electric shock due to unsuitable motor temperature evaluation system
Voltage 󹪞ashovers to the electronics of the converter can occur in motors without safe
electrical separation of the temperature sensors in accordance with IEC61800‑5‑1 when the
motor develops a fault.
• Install a temperature monitoring relay 3RS1… or 3RS2…
• Evaluate the temperature monitoring relay output using a digital input of the converter, e.g.
using the "External fault" function.
WARNING
Fire due to inadequate ventilation clearances
Inadequate ventilation clearances can cause overheating of components with subsequent 󹪝re
and smoke. This can cause severe injury or even death. This can also result in increased
downtime and reduced service lives for devices/systems.
• Ensure compliance with the speci󹪝ed minimum clearance as ventilation clearance for the
respective component.
NOTICE
Overheating due to inadmissible mounting position
The device may overheat and therefore be damaged if mounted in an inadmissible position.
• Only operate the device in admissible mounting positions.
WARNING
Unrecognized dangers due to missing or illegible warning labels
Dangers might not be recognized if warning labels are missing or illegible. Unrecognized
dangers may cause accidents resulting in serious injury or death.
• Check that the warning labels are complete based on the documentation.
• Attach any missing warning labels to the components, where necessary in the national
language.
• Replace illegible warning labels.
