4.1 Steps for mounting the modules
The MSI 400 system is only suitable for
mounting in the switch cabinet with a minimum
protection class of IP 54.
WARNING
In an MSI 400 system, the MSI 4xx base module is on the

far left, immediately followed by both optional gateways on
the right. Then followed by the extension modules.
Make sure appropriate ESD protective measures are main-

tained when mounting. Otherwise, the internal safety bus
may be damaged.
The connection between the modules is done via the

integrated connector in the housing.
Please note, when replacing a module, the MSI 400 mod-

ules are pushed apart approx. 10 mm before the corre-
sponding module can be removed from the standard rail.
Take the appropriate measures to prevent foreign objects

from obstructing the connector openings.
Mount acc. to EN 50274.

The modules are contained in a 45 mm or 22.5 mm wide

installation housing for 35 mm standard rails in accordance
with EN 60715.

4.1.1 Steps for mounting the MSI 4xx base module
 Pull the latching foot outwards with a screwdriver.
 Hook the module onto the standard rail.
Important! Make sure the shield spring is seated correctly.
The module's shield springs must be securely attached to
the standard rail and have a good electrical contact.
 Swivel the module onto the standard rail.
 Slide the latching foot against the standard rail with a
screwdriver until the latching foot snaps into place with an
audible CLICK.
 Make sure that the module is firmly mounted onto the
standard rail. Try to remove the module from the standard
rail with a little pressure. If the module remains firmly
connected to the rail with this test, the mounting is
correct.
