6.2. Replacing the Fan Unit

Replacement of the fan unit is not required as a preventative measure. Only if an alarm
indicates a malfunctioning of a fan must the unit be exchanged.



Note:

Please observe that the fan unit can only be replaced as a whole. Do not
remove the fans separately.

Read and observe chapter

1.2 Health and Safety

as well as the instructions in section

6.1 General

before starting with the replacement.

Switch off the Remote Unit. Make sure mains is disconnected for the
following replacement procedure.

Then, proceed as follows:

2. Loosen the four tallow-drop screws

M4x8 by which the fan plate is screwed
to the cabinet. Remove the four screws
and the corresponding washers.

3. Remove the fan unit – by putting slight

pressure on the fan plate cover – to a
position that allows access to the fan
connector and the earth-bonding
cable.

4. Unscrew the fan connector and then

disconnect the earth-bonding cable.

5. To mount the new fan unit, re-

connect the earth-bonding
cable and the fan connector
(see

step 4

). Then, place the

fan unit back into its original
position and fasten it tight:

6. Screw the whole fan unit to the cabinet with the four tallow-drop screws M4x8 (see

step 2

). In order not to exceed the specified torque of 3.3 N-m, use an appropriate

tool.
