Putting the AC 3200 into operation
̈
Ensure that the base of the AC 3200 is clean and free from
grease before fitting the rubber feet.
̈
Fix the rubber feet to the base of the AC 3200 by peeling off
the backing paper and fitting them as shown in the diagram
on the left.
̈
Place the AC 3200 on an even, horizontal surface.
Rack-mounting
CAUTION! Risks when rack mounting the AC 3200!
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 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 as the uppermost device
in the rack.
̈
Provide for a duct or vent space of 1 U above
the AC 3200 to ensure that the heated air can
dissipate.
̈
Make sure the mechanical loading of the rack is
even to avoid a hazardous condition such as a
severely unbalanced rack.
̈
When connecting the device to the power
supply, observe the information indicated on
the type plate. Avoid circuit overloading. If
necessary, provide overcurrent protection.
̈
Ensure a reliable mains ground connection of
the device by taking appropriate measures.
̈
When installing the device in a closed or multi-
rack assembly, please note that intrinsically
harmless leakage currents of the individual
devices may accumulate, thereby exceeding
the allowable limit value. As a remedy, ground
the rack via an additional ground connection.
