5.1 Selecting the Mounting Location

Requirements for the mounting location:
Radio interference in living areas possible due to the Cluster Controller
The Cluster Controller is a device of ITE class A (EN 55022) and can cause radio interference in
living areas.
• Take suitable measures for shielding radio waves when used in the vicinity of living areas.
☐ The mounting location must be indoors.
☐ The ambient conditions at the mounting location must be suitable for the operation of the
Cluster Controller (see Section 9 "Technical Data", page 77).
☐ The mounting location must be protected against dust, moisture and corrosive substances.
Observe the maximum cable length:
☐ Observe the respective maximum cable length of 100 m between two nodes in the Speedwire
network and in the local area network (LAN).
☐ When connecting a digital or analogue signal source (e.g. remote terminal unit, ripple control
receiver), observe the maximum cable length of 30 m from the Cluster Controller to the signal
source.
☐ When connecting a temperature sensor in a four-conductor connection, observe the maximum
cable length of 20 m from the Cluster Controller to the temperature sensor.
☐ When connecting a temperature sensor in a two-conductor connection, observe the maximum
cable length of 2.5 m from the Cluster Controller to the temperature sensor.
