Injury caused by a rotating fan
Touching a fan while it is rotating can result in injury.
• Switch off the supply voltage to the converter.
• Wait until the fan is stationary before working on it.
Electric shock as a result of a residual charge in power components
After the power supply has been switched off, it takes up to five minutes until the capacitors in
the converter have discharged so that the residual charge is at a non-hazardous level.
Therefore, touching the converter immediately after powering off can result in electric shock
due to residual charge in the power components.
• Check the voltage at the converter connections before releasing the connections at the
Electric shock when live parts are touched
After the fan unit is removed, the live components of the converter are no longer protected
from being touched. Contact with live parts can result in death or serious injury.
• Before replacing the fan, switch off the power supply at terminals X1: L1, L2, L3.
• Check that the fan unit is de-energized before removing it.
