Arrangement of the devices, air guides/drip protections, blowers
Pay particular attention to the maximum allowed air intake temper‐
ature of devices when they are arranged in multiple lines in the
control cabinet.
If possible, place devices with a high degree of power dissipation
(e.g. supply units with braking resistors, DC bus resistor units)
● in the top line and
● near the outlet air aperture to the cooling unit
Mount air guides between the lines to
● protect the devices in the upper lines against the warm outlet
air of the devices beneath and
● protect the devices beneath against penetration of liquids (e.g.
dripping condensation water or leaking cooling liquid)
Additional blowers convey the outlet air to the cooling unit and cool‐
ing air to the upper lines.
At the installed control cabinet, check the air intake temperature of
all devices.
To extend the module bus connection, the accessory RKB0001 is
available. Observe the assignment.
