3.14 Assembly of Converter, Size Classes G and H, with
Forced Air Cooling and Integrated Liquid Circulation
System (Cooling Type F)
Converters of size classes G and H comprise the following elements: line
filter, converter and heat exchanger. The converter and heat exchanger
are mounted on a common mounting plate and are fully connected. The
line filter has its own mounting plate as a result of its weight.
•
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 drive units are mounted in a cabinet, the cooling air
requirement of the units must be calculated (refer to Technical data
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.
•
First mount the line filter, then the converter and heat exchanger
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.
