Configuration
2.1.7 Multi−shelf Configuration
2−14
A multi−shelf configuration can be made up of a maximum of three shelves. Nor
mally only one fan unit mounted in the lower unit is required for heat dissipation.
To ensure easy installation and removal of the fan unit, sufficient clearance should be
provided under the corresponding unit.
Installation of a second fan unit can be necessary, depending on the expansion
structure of the two upper units, e.g. the addition of modules having a higher power
consumption.
Appropriate clearance should also be provided for these units.
The module description gives details when to install a fan unit.
The following illustration shows a possible three−shelf configuration consisting of
19 " basic and expansion units with clearances provided for fan unit installation and
removal plus the dimensions to be observed.
