Installation
When installing or removing modules and when modifying the system,
the relevant precautions against electrostatics have to be taken in
order to prevent damage to internal components of the system.
Before installing or removing a module, always touch a grounded part
of the system in order to eliminate a given difference in potential bet-
ween your body and the system. Using antistatic textile covers and
antistatic floor mats will reduce the danger of electrostatic discharge.
5.2.1
Installing the DC Drawers in a Customer Rack
The power supply units can be installed in any rack complying with the
19” industrial standard.
For successful installation in a rack, the respective demands on the
electric and cooling system have to be met.
•
If multiple drawers are to be installed in a rack we recommend to
provide three phase power to the rack in order to provide each
drawer with a dedicated supply and one phase to each drawer.
•
Particular care has to be taken that the heat generated during
operation is dissipated. The heat generated depends on the power
output by the module and the ambient conditions.
•
The heat sink of the module is mounted on the right. Make sure that
the cooling device is mounted in a way allowing the cooling air to
pass freely on this side.
•
For each group of four power supply modules installed one cooling
drawer is required. The cooling drawers must be installed directly
under the power supplies in order to ensure sufficient cooling.
•
In case a filter element is used to clean the intake air, regular
inspection and cleaning of the filter depending on the ambient
conditions is required to maintain the airflow volume.
•
To prevent thermal overload, the system is protected by
thermoswitches which are reset automatically after cooling down.
