3.15 Assembling Liquid-Cooled Converters, Size Classes G
and H, with External Heat Exchanger
General Notes Regarding Assembly
Converters of size classes G and H comprise the following elements: line
filter, converter and heat exchanger. The converter, line filter and heat
exchanger are each mounted on a separate mounting plate. In externally
assembled heat exchangers, the converter is not cooled by the air flow of
the heat exchanger. This means that additional fans are provided on the
converter.
•
Assembly must be carried out perpendicular to a level construction
area.
•
To ensure that the warm exhaust air can flow without impedance, a
space with a height of at least 200 mm must be maintained above the
devices.
•
When the devices are mounted in a cabinet, the cooling air
requirement of the units must be calculated (refer to Technical data,
section 3.8, 3.9) and the cabinet ventilation appropriately dimensioned.
•
The fastening screws are shown in the drilling templates of the
dimension drawings.
•
Two hoisting support points are provided to mount the units using a
crane. These are let in at the top of the mounting plate on both sides
and secured using a screw (refer to the dimension drawings).
•
First mount the line filter, then the converter above the mounting plate.
The two mounting plates must be assembled, as shown in the
dimension drawing, without any clearance between so that the cooling
airflow is not impeded. The busbars to connect the line filter and
converter are supplied with the equipment.
•
Attach the external heat exchanger to the desired location. This can be
mounted on the roof or wall of the cabinet. See Fig.: 3-51 , Fig.: 3-52 .
Additional technical data are described in documentation
DOK-RD500*-RD500*SUPPL-FKxx-EN-P (Accessories).
•
Connect the cooling circuit of the converter to the heat exchanger
using the heat exchanger hoses; for additional information, refer to
3.16 . Depending on the requirements, the heat exchanger hoses must
be ordered together with the converter.
Note: Your distributor can provide you with further information
regarding coolant hoses, hose nozzles, couplings, angular
connections, etc.
