7.4 Removing a Head Station from the DIN-Rail

On some head stations, the supply connections are located in an I/O-module-like housing
part. This part is securely connected to the rest of the head station housing. When pulling
out a head station of this type, be sure to pull the release tabs of both housing parts at
the same time. This is essential in order to avoid damaging the internal connection.
Follow these steps to remove a head station from a DIN-rail:
1. Use an operating tool to turn the DIN-rail locking cam until the nose of the DIN-rail
locking cam disengages from the DIN-rail.
2. Use the release tab to pull the head station off the DIN-rail and, if necessary, out of
the assembly. To remove head stations with two release tabs, both tabs must be
pulled at the same time!
ð When the head station is pulled out of an assembly, the electrical connections of the
data contacts or power jumper contacts to the subsequent I/O module are separated.
Special Case: Head Stations with Two DIN-Rail Locking Cams
Some head stations have two DIN-rail locking cams. In this case, both DIN-rail locking
cams must also be released in order to detach the head station from the DIN-rail.
