Installing the power supply unit
6.1
Fastening the power supply unit
When selecting the installation location, observe the following instructions:
•
The power supply unit must be installed vertically on a wall (maximum ambient
temperature 50 °C) or horizontally on the ground or on a pedestal (maximum
ambient temperature 40 °C and maximum load 75 %).
•
The optimum installation position is vertically on a wall.
•
The power supply unit must be installed in a location that is protected from
moisture.
•
The power supply unit must not be installed in areas with easily flammable
materials (e.g. gas cylinder lockers).
•
The power supply unit must not be installed in a dusty environment.
•
The place of installation must be well ventilated. A ventilation system must be
available for installations in small, enclosed spaces. Please observe the minimum
clearance around the power supply unit (fig.
3
, page 4).
•
There must be free space in front of the ventilation grills.
•
When ambient temperatures are higher than those stated above (such as in
engine or heating compartments, or when exposed to direct sunlight), the heat
produced by the power supply unit when under load can lead to automatic
shutdown.
•
The installation area must be a level and sufficiently sturdy surface.
