RackPack 4
Scope Of Delivery
•
The RackPack 4 frame including all blind panels and the front panel (if modules are not
fitted already). Please note that all modules are shipped without the aluminum front
panel. You need it when you fit a module into the frame. Therefore make sure that you
handle the aluminum front panels with the same care and prudence as any other unit
surface. All screws holding front and rear blind and front panels are needed for the fitting
of modules. Two additional screws are shipped with every module.

Please save the original packaging. In service cases the original packaging ensures a
safe shipping and handling. It is also useful for your own transports if you don’t use a
special housing or rack.
Recommendations On Module Configuration
Do not place preamp modules in the slot next to the internal power supply to avoid interfer-
ence. If more than three preamp modules are required, we recommend to use the RackPack 8
frame, model 2710, with external power supply.
The tube module TwinTube is supplied with very high currents. Therefore, two TwinTube
modules are the maximum for one RackPack 4 frame.
Placement
Place the unit on a level and stable surface. The unit’s enclosure is EMC-safe and effectively
shielded against HF interference. Nonetheless, you should carefully consider where you place
the unit to avoid electrical disturbances. It should be positioned so that you can easily reach
it, but there are other considerations. Try not to place it near heat sources or in direct sunlight,
and avoid exposure to vibrations, dust, heat, cold or moisture. It should also be kept away
from transformers, motors, power amplifiers and digital processors. Always ensure sufficient
air circulation by keeping a distance of 4-5 cm/2 inches to other units and to the sides of the
unit.
Rack Mounting
Be sure that both above and below the machine you maintain a distance of 4-5 cm/2 inches
in order to eliminate electromagnetic or high frequency interference from other equipment.
Moreover, this will ensure adequate air circulation to prevent overheating. Do NOT locate
other machines that produce excessive heat below the unit. The rear side of the machine
should be properly supported – especially when transport is involved.
