• The cross section of the sense cables is noncritical. However, it should be increased with
increasing cable length. Recommendation: for cables up to 5 m use at least 0.5 mm²
• Sense cables should be twisted and laid close to the DC cables to damp oscillation. If neces-
sary, an additional capacitor should be installed at the load/consumer to eliminate oscillation
• The sense cables must be connected + to + and - to - at the load, otherwise both systems
may be damaged
• In master-slave operation, the remote sensing should be connected to the master unit only

2.3.9 Installation of an AnyBus interface module
Thevariousinterfacemoduleswhichareavailableforthedevice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.
