Shielded ground
The shielded ground wire of the twisted pairs cables is connected to the
front panel as a conductor.
Beware of possible short circuits when connecting a cable section with
conductive shield braiding.
ESD Guidelines
The modules are equipped with electrostatically sensitive components.
These can be destroyed, or their life cycles reduced, by the effects of an
electrical field or by a charge equalization if the connections are touched.
You will find information about electrostatically endangered assemblies in
DIN EN 61340-5-1 (2007-08) and DIN EN 61340-5-2 (2007-08).
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 45.
Operating the device in the maximum surrounding air temperature and
stacking devices: When installing the device, make sure there is at
least one 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.
Exclusively use the device with a fan module.
Fans are subject to natural wear. If one or more fans in the fan module
fail, function and lifetime of a device can be negatively affected or the
device may fail completely. Use the monitoring functions of the device
for individual fans and temperature. Depending on your installation
conditions, it may be possible to continue operating your device after
one fan has failed.
Check the temperature measured by your device: In the Command
Line Interface, use the command: show temperature; in the Graphical
User Interface (GUI) in the Basic settings dialog: System,
Temperature. The displayed temperature must not exceed the
maximum value.
