Requirements for Mounting

Requirements for the mounting location:
Product can cause radio interference in living areas
The product 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 the Cluster Controller is 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, page 78).
☐ The mounting location must be protected against dust, moisture and corrosive substances.
Maximum permitted cable lengths:
☐ Observe the maximum cable length of 100 m each between any two nodes in the Speedwire
network and in the LAN.
☐ When connecting a digital or analog 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 using the four-conductor connection technology,
observe the maximum cable length of 20 m from the Cluster Controller to the temperature
sensor.
☐ When connecting a temperature sensor using the two-conductor connection technology,
observe the maximum cable length of 2.5 m from the Cluster Controller to the temperature
sensor.
Minimum clearances:
☐ The minimum clearances must be maintained to ensure adequate heat dissipation.
