3.12 Assembly of Converter Size Classes A to E
•
The RD 500 units, sizes A to E are modular and are designed for
mounting in cabinets.
•
The units have a 22.5 mm mechanical grid pattern. Several drive units
can be mounted next to one another without any intermediate space
(with the exception of converter size classes A - B with cooling type P)
when using mounting rails with tapped holes (also refer to the
assembly example).
•
Assembly must be carried out perpendicular to a level construction
area.
•
A minimum clearance of 100 mm above and below the unit must be
maintained to ensure that the cooling air can flow unrestricted.
