2.3.9 Installation of an interface module
Theoptionallyobtainableinterfacemodulescanberetrottedbytheuserandareexchangeablewitheachother.
The settings for the currently installed module vary and need to be checked and, if necessary, corrected on initial
installation and after module exchange.
• Common ESD protection procedures apply when inserting or exchanging a module.
• Thedevicemustbeswitchedo󰀨beforeinsertionorremovalofamodule
• Never insert any other hardware other than an interface module into the slot
• If no module is in use it’s recommended that the slot cover is mounted in order to avoid internal
dirtyingofthedeviceandchangesintheairow.
Installation steps:
1. 2. 3.
Remove the slot cover.
If needed, use a screw
driver.
Insert the interface module into the slot. The
shape ensures correct alignment.
When inserting take care that it’s held as close
as possible to a 90° angle to the rear wall of
the device. Use the green PCB which you can
recognize on the open slot as guide. At the
end is a socket for the module.
On the bottom side of the module are two
plastic nibs which must click into the green
board (PCB) so that the module is properly
aligned on the rear wall of the device.
The screws (Torx 8) are pro-
vided for xing the module
and should be fully screwed
in. After installation, the
module is ready for use and
can be connected.
Removal follows the reverse
procedure. The screws can
be used to assist in pulling
out the module.
