2.3.8 Connecting the “Share” bus
The “Share” connector on the back side of the device can be used in addition to a DC parallel connection.It serves
to balance voltage of multiple in constant voltage operation or when using the integrated function generator of the
master unit. Alternatively, it can be connected to a compatible power sources, i.e. power supplies of series PS 9000
3U or PSI 9000 3U, in order to run a two-quadrants operation. Further information for these modes of operation
can be found in sections „3.9.3. Two quadrant operation (2QO)“ and .
For the connection of the share bus the following must be paid attention to:
• Share bus connection is only allowed between up to 10 units of the same kind, i.e. electronic
loads, or to
• If, in order to set up a two-quadrants operation, multiple loads are operated in parallel to a
power supply or power supplies, then the load must be connected in master-slave mode and
only the master load may be connected to 1 power supply via “Share” bus. The master load
then controls the power supply or the parallel connection of multiple power supplies.
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.
