UA 412 S - complete design
The case controller is fastened on the DIN rail (35 mm) using two retaining springs. The DIN rail must have a
minimum height of 5 mm.
The case controller may only be mounted on a DIN rail and operated as an integrated regulation and
control device (EN60730). All supply lines from and to the case controller, particularly those of the
CAN bus, must be shielded (cable type: LiYCY)! If sensor cables are exclusively laid within the
refrigerated case to be monitored, and sources of interference (e.g. parallel power lines) are not
anticipated, then it is possible to dispense with shielding (see operating manual
Introduction, General
) As a general rule, care should be taken to ensure that signal
safety and connection instructions
cables and cables carrying mains voltage are routed in separate cable channels
Protection type and dimensions can be found in the chapter
.

Step 1: The two retaining springs on the underside of the device must be pulled out using a flat-blade
screwdriver until they click into place.
In order to carry out the assembly / dismantling, there must be a distance of at least 8 mm from the
next component (e.g. cable duct), otherwise the retaining springs cannot be pulled out.
