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 A
C 3200
-II specifications�
When installing the device in a rack, take good care not to affect the ventila-
tion 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 or on top of 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 appropri-
ate measures – especially when you are using multi-outlet power strips or
extension cables
