2.4 Placing the Communication Unit
Because the Communication Unit comes in two versions, the following description
contains:
• one section for the Communication Unit and
• one section for the 19” Rack Communication Unit
2.4.1 Where to place the Communication Unit
Temperature conditions
The Communication Unit must be placed in a ventilated area with free space around
all sides of the unit, except the bottom side.
For correct operation of the Communication unit the ambient temperature shall be
within - 25°C to + 55°C.
If the Communication Unit is installed in a location where the ambient temperature
may exceed 45°C, we recommend placing the Communication Unit where uninten-
tional contact is avoided. If the maximum ambient temperature does not exceed 45°C,
the Communication Unit can be placed in a public area.
Grounding access
The Communication Unit is designed with a case for bulkhead or desktop installation.
The case is equipped with mounting brackets, making it possible to secure the unit on
a bulkhead.
See the outline drawing at the end of this manual.
Important: The Communication Unit must be placed in an area where access to the
hull or equivalent grounding can be reached within 0.5 m.
