Installing modules on hat rail

This is only for switch boxes with protection class IP 54 or higher!
The MSI 400 system is only suitable for installations in a switchbox having at least protection
class IP 54.
Notes
• Basic safety
Gateways and extension modules may not be removed or added when the operating voltage is
switched on.
• Grounding
The hat rail must be conductively connected to the protective conductor (PE).
• ESD protection measures
Note the suitable ESD protection measures during installation.
Failure to do so could result in damage to the internal safety bus.
• Protect connector openings
Undertake suitable measures so that no foreign bodies can penetrate connector openings, particularly
those for the program removable storage.
• Module width:
The modules are placed in a mounting box that is 22.5 mm or 45 mm wide depending on type.
• Quality of hat rail
The mounting boxes are suitable for 35 mm hat rails as per EN 60715.
• Sequence of modules:
The MSI 400 system has the controller module on the far left. The two optional gateways follow directly
to the right next to the controller module. The expansion modules only follow thereafter.
• Save space for subsequent model replacement
The modules are connected via the plug connection integrated into the housing. Note that the MSI 400
modules must be pulled about 10 mm apart before a module replacement so that the corresponding
module can be removed from the hat rail.
• Standards to be considered
Installation according to EN 50274
Step 1: Installing a controller module
Ä Using a screwdriver, pull the snap-on foot outward.
Ä Hang the module on the hat rail.
Important! Make sure that the shielding spring fits correctly.
The shielding spring of the module must be placed onto the hat rail so that it is secure and has good
electrical contact.
