4.5.2 Installation guidelines
4.5.2.1 Installing the interface module
The interface module is designed for installation in a switchgear cubicle (IP20) and can therefore only be
mounted on a standard DIN rail (deep rail in acc. with EN50022)
Installation
•
Lower the module onto the DIN rail from above.
•
Then swivel it downwards until the slide mechanism on the module snaps onto the rail.
•
You may install other modules on the rail to the left and right of the interface module.
•
Clearance of at least 5 cm must be provided above and below the module to allow for heat dissipation.
•
Connect the standard DIN rail to the equipotential bonding strip of the switchgear cubicle. The
connecting wire must have a cross-section of at least 10 mm
2
.
•
Install an earth terminal immediately next to the interface module so that the flexible wire (1.5 mm
2
)
used for screen bonding can be as short as possible.
Deinstallation
•
First disconnect the power supply and signal cables.
•
Then use a screwdriver to press the slide mechanism on the module downwards.
•
Now swivel the module off the DIN rail.
