CAUTION
Injury caused by a rotating fan
Touching a fan while it is rot
ating can result in injury.
• Switch o󹪜 the supply voltage to the converter.
• Wait until the fan is stationary before working on it.
WARNING
Electric shock as a result of a residual charge in power components
After the
power supply has been switched o󹪜, it takes up to 󹪝ve 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 o󹪜 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
converter.
WARNING
Electric shock when live parts are touched
Af
ter the fan unit is remo
ved, 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 o󹪜 the power supply at terminals X1: L1, L2, L3.
• Check that the fan unit is de-energized before removing it.
• Wait until the discharge time speci󹪝ed on the warning labels has elapsed.
