Lateral installation distances

Normally, the following installation clearances are recommended: 40 mm above, 20 mm below and 5 mm at the left and right-hand sides if the device is continuously loaded by more than 50% of the rated output. Increase this distance to 15 mm if the neighboring device is a source of heat (e.g. another power supply unit).

The distance between the power supply units and the redundancy module can be reduced to zero if the following conditions are met:

• 1+1 redundancy applications.
• The power supplies are also from Beckhoff.
• The redundancy module is located between the two power supply units.
• The output voltage is set to the same level on both power supply units.
