11.3 Mounting / Removing I/O Modules
11.3.1 General
Note: The Power Module (BSS-310A)
must always be mounted first on the rail
- at the bottom - before any other
modules. The Communication Module
(BSL-310) is then mounted on top of
the Power Module. If the optional Dual
Power Monitoring Module BSS-311 is
to be used, this module always has to
be mounted at the bottom – before
BSS-310A and BSL-310.
All other modules can be mounted in
arbitrary order on top of these modules.
11.3.2 Mounting
The connection block on the I/O module must be pointing to the right
when the module is to be inserted in a BS-420/BC-420 cabinet.
◼ Snap the right side of the
fastener onto the mounting
rail (1), then press the module
slightly inwards (2) until the
left side fastens.
◼ Then, carefully press the
module downwards as far
as possible. Make sure that the module is properly connected to the
module below.
When the system is to be configured at a later point, note that the
AutroSafe Configuration Tool graphically shows the first module on the
top of the figure and the following in descending order. This may be
opposite to the physical mounting, and must be taken into
consideration when configuring the system. Also note that the
configuration tool does not show the BSS-311 and BSL-310.
