RFC 4072S

3.3 Mounting the RFC 4072S
Mount the RFC 4072S on 35 mm standard DIN rails with a height of 15 mm (for ordering
data, see Section “Accessories” on page 230 ). The distance between the DIN rail fastening
points must not exceed 160 mm (see Figure 3-3 on page 73 ).
Figure 3-2 Mounting the RFC 4072S
• Place the RFC onto the DIN rail from above (A in Figure 3-2 ).
• Tilt the RFC downwards until the spring-loaded holder on the back of the device snaps
into place with a click (B).
• Finally, make sure that the RFC is securely mounted on the DIN rail.
The following Figure 3-3 shows the RFC 4072S which is mounted on a DIN rail in its stan-
dard installation position.
To avoid contact resistance only use clean, corrosion-free DIN rails. Before mounting the
devices, an end bracket should be mounted to the left of the RFC 4072S to stop the
devices from slipping on the DIN rail. The end bracket should only be mounted on the
right-hand side once the RFC 4072S has been mounted.
The following end brackets can be used:
– E/NS 35N (Order No. 0800886, fixed using a screw)
– CLIPFIX 35 (Order No. 3022218, snapped on without using tools)
– E/UK (Order No. 1201442, fixed using screws)
NOTE: Overheating of the RFC possible
When installing the RFC make sure that the vents can be freely accessed. Otherwise, the
RFC may overheat. To ensure good ventilation, leave a gap of more than 10 cm above
and below the RFC.
Do not install devices below the RFC 4072S that could additionally heat the RFC 4072S
up.
If you wish to operate the RFC with the RFC FAN MODULE fan module (Order No.
2404085), you must mount the fan module first, before mounting the RFC on the DIN rail.
Please refer to the instructions in Section “Mounting the RFC FAN MODULE fan module”
