Rack-mounting
CAUTION
Risks when rack mounting the AC 3200-II
When installing the device in a closed or multi-rack assembly, please consider
that, during operation, the ambient temperature, the mechanical loading and
the electrical potentials will be different from those of devices which are not
mounted into a rack:
The ambient temperature within the rack must not exceed the
temperature limit specified in the AC 3200-II specifications.
When installing the device in a rack, take good care not to affect the
ventilation required for safe operation. If necessary, provide additional
ventilation.
In order to avoid heat accumulation, make sure to install the AC 3200-II as
the uppermost device in the rack.
Provide for a duct or vent space of 1 U above the AC 3200-II to ensure that
the heated air can dissipate.
Never place several NT 12-125D mains units directly next to one another.
Make sure the mechanical loading of the rack is even to avoid a hazardous
condition such as a severely unbalanced rack.
Make sure the two cables of the NT 12-125D mains unit are not exposed
to mechanical loading (e.g. pulling).
When connecting the device to the power supply, observe the information
indicated on the mains unit. Avoid circuit overloading. If necessary, provide
overcurrent protection.
Ensure a reliable mains ground connection of the device by taking
appropriate measures – especially when you are using multi-outlet power
strips or extension cables.
To mount the AC 3200-II into a 19'' rack:
Slide the AC 3200-II into the 19'' rack.
Secure the rack mount "ears"
separately).
