If you are operating the device in a 19" switch cabinet: install sliding/
mounting rails for supporting the weight of the device.
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.
Device casing
Only technicians authorized by the manufacturer are permitted to open
the casing.
Make sure there is at least 3.94 in (10 cm) of space in front of the
ventilation slits of the casing.
See “General technical data” on page 45.
Never insert pointed objects (narrow screwdrivers, wires, etc.) into the
device or into the connection terminals for electric conductors. Do not
touch the connection terminals.
Do not touch the housing during operation or shortly after switching off
the device. Hot surfaces can cause injury.
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.
Qualification requirements for personnel
Only allow qualified personnel to work on the device.
Qualified personnel have the following characteristics:
