Putting the conference system into
operation
Preparing the ADN CU1 central unit for operation
Setting up the central unit on a flat surface or mounting it into a rack
If you want to place the central unit on a flat surface:
왘 Make sure that the air vents are not covered or blocked.
왘 Place the central unit on a flat surface as shown.
If
you want to mount the central unit into a 19" rack, the central unit must be sup-
ported and fixed to the rack using additional components.
CAUTION
Danger of material damage and personal injury when rack mount-
ing the central unit!
When installing the product in a closed or multi-rack assembly,
please consider that, during operation,
• the ambient temperature within the rack may drastically
increase,
• high mechanical loading may be exerted on e.g. the housings or
cables,
• intrinsically harmless leakage currents of the individual mains
units may accumulate, thereby exceeding the allowable limit
value.
This can cause material damage and electric shocks.
왘 Always mount the central unit using a suitable rack tray. Make
sure that the mechanical loading of the rack is even.
왘 Make sure that the ambient temperature within the rack does not
exceed the perm
issible temperature limit specified in the specifi-
cations (see page 240). Ensure sufficient ventilation; if necessary,
provide additional ventilation.
왘 Provide for a duct or vent space of 1 U above the ADN CU1 central
unit to ensure
that the heated air can dissipate.
왘 When connecting to the mains powe
r supply, observe the
information indicated on the type plate. Avoid circuit
overloading. If necessary, provide overcurrent protection.
왘 Ground the rack via an additional ground connection.
