Two fans are mounted on the lower side of the inverter, an internal fan
for cooling the control electronics and a unit fan for cooling the power
section.
♦ Opening the unit:
• Loosen the 2 mounting screws in the front at the top of the unit.
There is no need to take the screws right out. Slots are provided
in the housing to allow the front of the unit to be released when
the screws have been loosened.
• Carefully swing the front of the unit forwards (to an angle of
about 30°) away from the housing.
• On the power section, open the locking lever on the ribbon cable
connector to the control electronics.
• Move the cover forwards and take it off.
♦ Remove the fan connection on the power section.
♦ Undo the four mounting screws or slide out the internal parts of the
insert rivets. Then remove the fan. The insert rivets can be re-used.
♦ Fit the new fan by reversing this sequence of operations. Make sure
that the arrow indicating the direction of rotation is pointing to the
inside of the unit.
♦ Undo the four mounting screws or slide out the internal parts of the
insert rivets. Then remove the fan. The insert rivets can be re-used.

the inside of the unit.
Make sure that the leads to the fan are connected the right way round.
