Danger to life when live parts are touched
Before replacing the fan, you must switch off the power supplies (400 VAC and 24 VDC). A
hazardous voltage is still present for up to five minutes after the power supply has been
switched off.
Contact with live parts can result in death or serious injury.
• Remove the device cover or the fan cover only after a certain time.
• Check for zero voltage before removing the component.
Note
When replacing the fan, you must observe the ESD regulations.
Only qualified personnel are permitted to install spare parts.
