2 Assembly and installation
2.1 Installation
NORDAC SK 5xxE frequency inverters are available in various sizes depending on the output. Attention must
be paid to a suitable position when installing.
The equipment requires sufficient ventilation to protect against overheating. For this the minimum guideline
distances from adjacent components above and below the frequency inverter, which could obstruct the air flow
apply.
(above > 100 mm, below > 100 mm)
Distance from device:
Mounting can be immediately next to each other. However, for the use of brake
resistances mounted below the device (not possible with …-CP devices), the greater width (Section 2.5) must
be taken into consideration, particularly in combination with temperature switches on the brake resistor!
Installation position
The installation position is normally vertical. It must be ensured that the cooling ribs on
the rear of the device are covered with a flat surface to provide good convection.
≥
100mm
≥
100mm
Warm air must be vented above the device!
If several inverters are arranged above each other, ensure that the upper air entry temperature limit is not
exceeded. (see also Section 7, Technical Details). If this is the case, it is recommended that an "obstacle" (e.g.
a cable duct) is mounted between the inverters so that the direct air flow (rising warm air) is impeded.
Heat dissipation:
If the device is installed in a control cabinet, adequate ventilation must be ensured. The
heat dissipation in operation is approx. 5% (according to the size and equipment of the device) of the rated
power of the frequency inverter.
