2.4.2 Where to place the 19” rack Communication Unit
Temperature conditions
For correct operation of the Communication unit the ambient temperature shall be
within - 25°C to + 55°C.
Note: If you install other equipment close to the Communication Unit in the rack, first
make sure the equipment can withstand the heat that may be dissipated from the 19”
Rack Communication Unit. In max. ambient temperature the surface of the Communi-
cation Unit may reach a temperature close to 70°C. We recommend to use a well ven-
tilated rack.
Grounding access
The Communication Unit is designed for installation in a 19” rack. We recommend
grounding the Communication Unit through the rack.
See the outline drawing at the end of this manual.
Important: The rack for the Communication Unit must be placed in an area where ac-
cess to the hull or equivalent grounding can be reached within 0.5 m.
