Device casing
Only technicians authorized by the manufacturer are permitted to open
the casing.
Keep the ventilation slits free to ensure good air circulation.
Make sure there is at least 3.94 in (10 cm) of space in front of the
ventilation slits of the casing.
Do not touch the housing during operation or shortly after switching off
the device. Hot surfaces can cause injury.
Mount the device horizontally in a cabinet or vertically on a flat surface.
Operating the device as a table unit is inadmissible.
See “Installing and grounding the device” on page 54.
Operating the device in the maximum surrounding air temperature and
stacking devices: When installing the device, make sure there is at
least 1 free rack space (approx. 5 cm) above the device, because heat
is discharged via the housing of the device.
If you are operating the device in a 19" switch cabinet: install sliding/
mounting rails for supporting the weight of the device.
Installation site requirements
Operate the device at the specified ambient temperature (temperature of
the ambient air at a distance of 2 in (5 cm) from the device) and at the
specified relative humidity exclusively.
When you are selecting the installation location, make sure you
observe the climatic threshold values specified in the technical data.
Use the device in an environment with a maximum pollution degree
that complies with the specifications in the technical data.
Strain relief
Note: If the strain relief is insufficient, there is a risk of torsion, contact
problems and creeping interruptions.
Relieve the connection points of cables and lines from mechanical
stress.
Design strain relieves in such a way that they prevent any mechanical
damage to cables, wires or conductors caused by external influences
or their own weight.
To prevent damage to device connections, connectors and cables,
follow the instructions for proper installation in accordance with DIN
VDE 0100-520:2013-06, sections 522.6, 522.7 and 522.13.
