EC-fans: Replacing fan package

WARNING:

Before starting the service operation, ensure that the electrical supply is reliably isolated; use the lockout/tag-out system. Always check with a voltmeter that the unit is electrically isolated and shut off.

WARNING:

EC-fans: Electrical load (>50 μC) between mains wire and protective earth connection after switching of the supply when switching multiple devices in parallel.

Electric shock, risk of injury. Ensure that you have sufficient protection against accidental contact.

Before working on the electrical connection, short the connections to the mains supply and PE.

EC-fans: Terminals and connections have voltage even in a unit that is shut off.

Electric shock. Wait for five minutes after disconnecting the voltage at all poles before opening the device.

WARNING:

EC-fans: High temperature at the electronics enclosure. Danger of burn injuries. Ensure that you have sufficient protection against accidental contact.

WARNING:

Cutting and crushing hazard when removing the spare parts from the packaging. Wear safety shoes, safety helmet and cut-resistant safety gloves.

Do not perform any repairs on the fan package. If the fan or its package is broken, return the fan to Fincoil LU-VE Oy for repair or replacement.

To replace the fan package

  1. Switch off the device through the control input.
  2. Switch off the current from the unit.
    Use lockout and tagout.

  4. Disconnect all cables.
    Disconnect the earth wire connection last.
  5. Open the motor bracket bolts and lift the fan unit up from the collar.
  6. Mount the new unit and connect the cables.
    Use old cable glands.
  7. When routing the cable, ensure that the screwed cable glands are arranged at the bottom.
    Always route the cables downwards.
  8. Tighten the cable to the motor bracket with UV-protected cable ties.
  9. Check the rotation and the general functioning of the fan on a test run.
