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
Make sure that the air vents are not covered or blocked.
Place the central unit on a flat surface as shown.
If you want to mount the central unit
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.
Always mount the central unit using a suitable rack tray. Make
sure that the mechanical loading of the rack is even.
Make sure that the ambient temperature within the rack does not
exceed the permissible temperature limit specified in the specifi-
cations (see page 240). Ensure sufficient ventilation; if necessary,
provide additional ventilation.
Provide for a duct or vent space of 1 U above the ADN CU1 central
unit to ensure that the heated air can dissipate.
When connecting to the mains power supply, observe the
information indicated on the type plate. Avoid circuit
overloading. If necessary, provide overcurrent protection.
Ground the rack via an additional ground connection.
