Mechanical installation
Important hints:
•
Use the power feed/feedback units as build-in devices only!
•
Observe free spaces!
-
Several power feed/feedback units in one cabinet may be installed next to
each other without spacing.
-
Keep a horizontal distance of at least 70mm to other components and to the cabinet
walls.
-
Keep a vertical distance of at least 150mm to other components and to the cabinet
walls.
•
Ensure that there are no obstacles in the way of the cooling air input and output.
•
If the cooling air is polluted (dust, dirt swirl, grease, aggressive gas) so that the func-
tion of the power feed/feedback unit may be impeded
-
Take sufficient countermeasures, e.g. separate cooling air, mounting of air filters, pe-
riodical cleaning.
•
Do not exceed the ambient temperature permissible during operation.
Provided mounting position
1
The power feed/feedback unit has been designed for vertical wall mounting (
±
15
°
) only.
Mounting is allowed only on a flat surface without using any kind of spacers. This kind of
mounting is necessary to guarantee the right way for the cooling air. A power loss of 3 %
from the maximum nominal power rating has to be calculated. Air-temperature may not
exceed 40 °C near the unit. Air-in- and air-out-openings at the top and the bottom of the
unit may not be concealed by installation materials such as cable ducts or other equipment.
Keep a distance of min. 15 cm to the air-in- and air-out-openings and a distance of min. 7
cm to beside mounted parts or cabinet-walls.
