– Ethernet interface X8
– Serial interface modules X12 and X13 (CECC-S)
– Multiple interface X14 (CECC-S)
– IO-Link Device Port X16 (CECC-LK and CECC-S)
– Encoder interface X11 (CECC-S)

Section 3.3.
5 Mounting, dismounting
Prior to mounting, installation and maintenance work:
Switch off power supply and secure it from being switched back on.
Mount the controller on an H-rail (
è
5.1) or on the wall (
è
5.2).
Note
Malfunction due to heat accumulation.
Mount the controller with sufficient space for heat dissipation.
Comply with limits of the ambient temperature ranges

5.1 H-rail mounting

Spring-loaded clip
Fig. 16 Mounting/dismounting with H-rail mounting
Assembly
The tilt position of the CECC when setting it onto the H-rail requires
a minimum distance between the H-rail edge and the mounting surface
so the CECC can be placed onto the H-rail without tilting.
Use H-rail with a minimum depth of 9 mm.
1. Place controller onto the H-rail from above.
2. Press the controller in the direction of the arrow.
The spring-loaded clip engages audibly on the H-rail.
Disassembly
1. Remove connections from the controller.
2. Pull the spring-loaded clip of the controller in the direction of the arrow using
a suitable tool (e.g. screwdriver). This unlocks the controller.
3. Tilt the unlocked controller from the bottom away from the H-rail.
4. Lift controller upward from the H-rail.

Assembly
Note
Damage to the controller from mounting onto uneven or flexible surfaces.
Mount the controller only on even, torsionally rigid surfaces.
1. Plan sufficient space for connecting the supply cables.
2. Drill holes into the mounting surface. Note the distances between the mounting
holes.
3. Fasten the controller with screws:
Make sure that the housing is not damaged.
Use M4 screws of appropriate length and a screw head diameter of maximum
7.0 mm. Tightening torque: 0.8 Nm ± 20 %.
Dismounting
1. Remove connections from the controller.
2. Remove the mounting screws.
3. Remove the controller from the mounting surface.
