NOTICE

If the terminals are not reconnected to the actual line voltage:

• The required cooling capacity cannot be provided because the fan rotates too slowly.

• The fan fuses may blow due to an overcurrent.

Note

The order numbers for fan fuses that have blown can be found in the spare parts list.
