MOUNTING INSTRUCTIONS IN STEPS
Before you start mounting the unit, read carefully “ Safety and Precautions” and
follow these steps. Choose a smooth solid surface for installation (a wall, panel,
etc.).
Follow these steps:
1. Unscrew the front cover and open the enclosure. Mind the flat cable that connect
the LEDs with the printed circuit board.
2. Fix the unit onto the wall or panel using the provided screws and dowels. Mind the
correct mounting position and unit mounting dimensions. (See
Fig. 1 Mounting
dimensions and Fig. 2 Mounting position .)
3.
Pay attention to the 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. Do not install the
controller above heating equipment or heat sources.
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.
