Cabinet placement on a cable channel
Note the following when you plan to place the cabinet on a cable channel:
• The cabinet structure must be sturdy enough. If the whole cabinet base is not supported
from below, the cabinet weight will lie on the sections that the floor carries.
• Equip the cabinet with a sealed bottom plate and cable entries to ensure the degree of
protection and to prevent the cooling air flow from the cable channel into the cabinet.

Heaters
Use a heater if there is a risk of condensation in the cabinet. Although the primary function
of the heater is to keep the air dry, it may also be required for heating at low temperatures.
