Installation of an interface module
The optionally obtainable interface modules can be retrofitted 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 off 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 is recommended that the slot cover is mounted in order to avoid internal
dirtying of the device and changes in the air flow.
Installation steps:
1.
2.
3.
With the help of a Torx
8 screw driver either
remove the slot cover
(dummy module) an al-
ready installed module.
The screws can be used
to assist in pulling out the
module.
Make sure the screws
are fully retracted. If not,
unscrew them further
and remove the module.
Insert the interface module into the slot. The
shape ensures correct alignment.
When inserting take care that it is 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 underside of the module are two plastic
nibs which must click into the green PCB so
that the module is properly aligned on the rear
wall of the device.
The screws (Torx 8) are pro-
vided for fixing 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.
2.3.9
Connecting the analog interface
The 15 pole connector (Type: Sub-D, D-Sub) on the rear side is an analog interface. To connect this to a control-
ling hardware (PC, electronic circuit), a standard plug is necessary (not included in the scope of delivery). It is
generally advisable to switch the device completely off before connecting or disconnecting this connector, but at
least the DC output.
The analog interface is galvanically isolated from the device internally. Unless absolutely re-
quired, do not connect any ground of the analog interface (AGND) to the DC minus output as
this will cancel the galvanic isolation.
