Switching ON the Forced Cooling Fan

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
  • Ensure that there are no combustible or flammable materials located near the blower.
  • Before switching ON, check the forced cooling fan for visible external damage and make sure the protective devices are functional.
  • Check the fan's air flow paths for foreign matter and remove any foreign matter found.
  • Apply the nominal supply voltage.
  • Start the forced cooling fan by changing the input signal.
  • Ensure no part is falling into the cubicle during service.
Failure to follow these instructions will result in death or serious injury.
WARNING
HAZARD OF INAPPROPRIATE OPERATION
The forced cooling fan should only be switched ON if it has been installed correctly and in line with its intended use, including necessary protective mechanisms, and professional electrical connections.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
NOTICE
HAZARD OF ABNORMAL USE CONDITIONS
  • Ensure there is no bearing damage, it can cause shorter service life.
  • Ensure the fan operates with low-vibration across the entire speed control range.
  • Operation with excessively high vibration levels can lead to premature failure.
  • Avoid severe vibration which can occur due to inexpert handling, transportation damage, and resultant imbalance or by component or structural resonance.
  • Avoid high vibration levels during fan commissioning.
  • Identify speed ranges with excessively high vibration levels and potential resonant frequencies.
  • Either run through the resonant range as quickly as possible with speed control or find another remedy.
Failure to follow these instructions can result in equipment damage.

This requirement also applies to devices that the customer installed with plugs, terminals, or similar connectors.
