3.
Pay attention to following instructions in order to minimize the operating
temperature:
3.1
Respect the distances both between the wall / ceiling and the device
and between two devices as shown in
Fig. 2
. In order to ensure sufficient
ventilation of the controller, clearance on every side has to be maintained.
3.2
When installing the device, please keep in mind that the higher you install it,
the warmer the device will get. For example, in a technical room the correct
installation height can be of great importance.
3.3
If maximum ambient temperature cannot be adhered to, please provide
extra forced ventilation / cooling.
Not respecting the abovelisted rules can reduce service life and relieves the
manufacturer of any responsibilities.
4.
Once secured in position, the mounting screws or bolts should be sealed to
maintain the IP rating of the enclosure.
5.
Because the controller enclosure is made of metal, it must be earthed and bonded
to other existing metal surfaces.
