Replacing the fan

The fan is located on the right underside of the unit.
♦ Undo the M4 x 8/T20 Torx screw securing the fan
♦ Extract the plug-in terminal X29
♦ Undo the M4 x 8/T20 Torx screw for earth connection
♦ Pull the fan out of the unit towards the front left
♦ Install a new fan in reverse order
♦ Before commissioning the unit, check that the fan
does not rub and also check the air flow direction.
The air must be discharged from the unit in the
upward direction.
8.2.2 Replacing modules (not double rectifiers)
The modules contain electrostatically sensitive devices. You must discharge your own
body before touching an electronic module. This is best done by touching a conductive
earthed object (e.g. a bare metal part of the control cabinet) directly beforehand.

The fan must only be replaced by qualified personnel.
Owing to the dc link capacitors, a hazardous voltage prevails for a further 5
min. after deenergisation.
Despite the fact that the power section is voltage-isolated, hazardous voltages
are present in the unit due to the external power supply for the fan.
