11.3.1 Guide to installation of expansion cards in slot 3

Remove the area of the front film colored yellow
(labeled slot 3).
Lever out the cover plates under the film.
Remove the small PCB (STO Bridge) which is
plugged into slot. Use suitable pliers.
Push the expansion card into the slot.
Use the screws provided to fasten the front plate of
the expansion card in place.
11.3.2 Option "F2", controlled Fan
To reduce noise emission the servo amplifiers can be ordered with the built-in option card F2.
This option cannot be built-in later. The F2 option card fits to slot2 or 3 (see part number
scheme on (➜ # 26)).
Option card F2 can be used combined with a card in slot 1 even if it is plugged to slot 2!
Function
The fan is switched on and off or runs with 50% rated speed depending on temperature. That
reduces the average noise emission.
