Mounting position
Alignment
The commutating reactor must be installed in the appropriate orientation in the cooling-air
flow, see following figure.

Figure 3-2
Distance from neighboring components
When the reactor is installed in the switch cabinet, a clearance of approximately 100 mm to
neighboring components is recommended. This clearance guarantees the heat dissipation of
the reactors. If the reactor is installed in a cabinet, it must be ventilated adequately.
Mounting holes, fastening screws
The commutating reactor is provided with 4 elongated holes. Layout and dimensions, see
dimension drawing (Section Dimension drawings (Page 33))
The commutating reactor must be fastened with 4 screws.
