5.12.2 Procedure
Use the images shown below for reference. To install or exchange an
interface module, proceed as follows:
1. Remove the slot cover. If needed use a screwdriver.
2. Check that the attachment screws of an already installed
module are fully retracted. If not, unscrew them (Torx 8) and
remove the installed module.
3. Insert the new interface module into the slot. The shape ensures
correct alignment.
4. When inserting, take care that it is held as
close as possible to a 90° angle to the rear
wall of the unit. Use the green PCB which
you can recognize on the open slot as
guide. At the end is a socket for the
module.
5. On the underside of the module are two
plastic tabs, which must click into the green PCB so that the
module is properly aligned on the rear panel of the unit.
6. The screws (Torx 8) are provided for fixing the module and
should be fully screwed in. After installation, the module is
ready for use and can be connected.
For removal, follow the reverse procedure. The screws can be used to
assist in pulling out the module.
5.13 Share Bus Connections
The “Share” bus connector on the rear panel is intended to balance the current of multiple
units in parallel operation, especially when using the integrated function generator of the
master unit. Alternatively, it can be connected to a compatible electronic load like the 6RL
Series, in order to create a two-quadrant source/sink system.
For the connection of the share bus, pay attention to the following issues:

Connection is only permitted between compatible units (See section 3.8.4,
“Share Connections“ for details) and between a max. of 32 units

If a two-quadrant system has to be set up where multiple power supplies are
connected to one electronic load unit or a group of electronic loads, all units
should be connected via the Share bus.

When not using one or several units of a system configured with Share bus,
because less power is required for an application, it is recommended to
disconnect unused units from the Share bus, because even when not powered,
they can have a negative impact on the control signal on the bus due to their
