Excessive torque can lead to damage.
5.5.3 Remote signal connections X11 and X12
The signalling and external setpoint specifications/switchover take
place via connectors X11 and X12 (pin assignment section 3.1;
functional description section 6).
When wiring with a shielded control cable, the enclosed shield terminal
to the left of X12 can be used if required.
Alternatively, the shield clamp can be removed to screw on an M3
cable lug or a screw base for cable ties .

5.5.4 Cooling and supply air
The switched-mode power supply works with convection cooling. The
air flows from bottom to top through the device and over the heat sink
at the rear. The supply and exhaust air must not be obstructed and
must be routed in such a way that it does not lead to heat build-up. The
supply air temperature must not exceed the specification in the
technical data (section 4.2).
