Installation Orientation
Install supply units in such a way that their longitudinal axis corresponds
to the natural direction of convection (connections for motor and power
downwards).
In this way the natural convection supports the forced cooling air current.
This avoids the generation of pockets of heat.

Fig. 6-7: Example of an arrangement
• Arrange the drive controllers with higher power needs and high
currents as close to the supply unit as possible. Ideally the drive
controllers should be distributed equally to the left and right side of the
power supply.
• Position DC bus capacitor unit next to drive with the greatest DC bus
continuous output.
• Position DC bus resistor unit next to drive with the greatest negative
feed power.
