2.3.8 Installation of an AnyBus interface module
The various interface modules, which are available for PSI 9000 2U standard version models with Anybus slot,
can be retrotted by the user and are exchangeable with other modules. 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 AnyBus-CompactCom 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 ow.
Installation steps:
1. 2. 3.
Remove the slot cover.
If needed use a screw
driver.
Check that the fixing
screws of an already
installed module are fully
retracted. If not, unscrew
them (Torx 8) and re-
move 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, 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.
Slide the module into place
as far as it will go.
The screws (Torx 8) are pro-
vided for xing the module
and should be fully screwed
in. After installation, tre mod-
ule 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.
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 abso-
lutely required, do not connect any ground of the analog interface (AGND) to the DC
minus output as this will cancel the galvanic isolation.
