Important hints
•
Use the power feedback units as build-in devices only!
•
Observe free spaces!
-
Several power 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
function of the power feedback unit may be impeded
-
Take sufficient countermeasures, e.g. separate cooling air, mounting of air fil-
ters, periodical cleaning.
•
Do not exceed the ambient temperature permissible during operation.
Provided mounting position
The power 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 dis-
tance of min. 7 cm to beside mounted parts or cabinet-walls.
