3.1 Environmental
Operating the equipment in an environment other than that stated in the specifications also
invalidates the safety compliance.
Do not use the equipment in an environment in which the unit is exposed to:
• Unpressurized altitudes higher than 2000 meters
• Extreme temperatures outside the stated operating range operating
temperature range 0 to + 50°C
• Excessive dust
• Moist or humid atmosphere above 85% RH
• Excessive vibration
• Flammable gases
• Corrosive or explosive atmospheres
• Direct sunlight
Use a slightly damp cloth to clean the casing of the equipment. Do not use any
cleaning liquids containing alcohol, methylated spirit or ammonia, ...
3.2 Rack Mounting Instructions
• Elevated Operating ambient - If installed in a closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be greater than room ambient. Therefore,
consideration should be given to installing the equipment in an environment compatible with the
maximum ambient temperature (Tma) specified by the manufacturer. 50°C.
• Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air
flow required for safe operation of the equipment is not compromized.
• Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous
condition is not achieved due to uneven mechanical loading.
• Circuit Overloading - Consideration should be given to the connection of the equipment to the
supply circuit and the effect that overloading of the circuits might have on overcurrent protection
and supply wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
• Reliable earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to the branch
circuit (for example use of power strips).
