Choosing a Suitable Location for Mounting
The VNM 250 is designed to be used either as a free-standing unit or mounted in a 19-inch
rack using optional mounting kits. Wherever the unit is mounted, observe the Environmental
Requirements listed below.
Environmental Requirements
ATTENTION:
•
The points in this section must always be observed whether the VNM 250 is
free-standing or rack-mounted.
•
Les indications de cette section doivent toujours être respectées, que le VNM 250
soit autonome ou monté en rack.
Orientation
The VNM 250 is designed to be used free-standing on a stable, horizontal surface. It can,
however, be used in any orientation subject to the necessary ventilation requirements.
Temperature
•
Do not install or operate the VNM 250 in an area where the ambient temperature
exceeds 35 °C (95 °F) or falls below 5 °C (35 °F).
•
The VNM 250 and its associated power supply produce heat, which can affect the
ambient temperature.
•
After the VNM 250 has been in use for a period of time, the external casing can become
slightly warm to the touch. Ensure that any adjacent surfaces are not affected by the
heat.
Ventilation
Do not obstruct the ventilation openings during use. The VNM 250 has an integral forced-air
cooling system. A fan draws air in through the ventilation openings in the front panel and
expels the heated air through the openings in the back panel. The fan speed is controlled
automatically by an internal temperature sensor. The fan can, therefore, appear to run faster
as the unit warms up or if the ambient temperature increases.
A self-resetting thermal cutoff shuts down the VNM 250 if the temperature exceeds design
limits.
