VN-Matrix 300 • Installation and Basic Setup Procedures 12
Temperature
DO NOT install or operate the VN-Matrix 300 in an area where the ambient temperature
exceeds 35°C (95°F) or falls below 5°C (35°F).
Remember that, as with all electronic equipment, the VN-Matrix 300 and its associated PSU
also produces heat which may affect the ambient temperature.
After the VN-Matrix 300 has been in use for a period of time, the external casing may
become slightly warm to the touch. Ensure that any adjacent surfaces will not be affected by
the heat.
Ventilation
DO NOT obstruct the ventilation grills during use. The VN-Matrix 300 has an integral
forced-air cooling system. A fan draws air in through the grille in the front panel and expels
warmed air through the grilles in the back panel. The fan speed is controlled automatically
by an internal temperature sensor. The fan may, therefore, appear to run faster as the unit
warms up or if the ambient temperature is increased.
A self-resetting thermal cut-out will shutdown the VN-Matrix 300 if the temperature exceeds
design limits.
Humidity and Water
DO NOT install or operate the VN-Matrix 300 in an area in which the ambient relative
humidity exceeds 85% or in an area that is prone to condensation.
DO NOT install or operate the VN-Matrix 300 near water or in a location which may be
prone to water seepage — the VN-Matrix 300 is not waterproof.
Rack Mount Requirements
CAUTION: For rack-mounted installations, the following criteria must be observed.
Mounting and Support
ALWAYS use the special rack-mount kits (available separately) to secure the VN-Matrix 300.
Full details on using the kit are included with the kit. It will be necessary to remove the four
feet before rack mounting.
DO NOT stand other units directly on top of the VN-Matrix 300 when it is rack-mounted as
this will place excessive strain on the mounting brackets.
Ventilation
ALWAYS ensure that the rack enclosure is adequately ventilated. Sufcient airow must be
achieved (by convection or forced-air cooling) to satisfy the ventilation requirements of all
items of equipment installed within the rack.
No additional ventilation gap is required above or below the VN-Matrix 300 and adjacent
surfaces or equipment.
Power Supply
ALWAYS ensure that the mains power supply is of the correct voltage and frequency for all
equipment within the rack, and that it has a good ground/earth connection.
Where a power strip (mains distribution batten) is used (of either a hard-wired or plug and
socket type), always ensure that the current rating of both the power strip and the supply is
sufficient for all equipment within the rack.
