This typically will require the rack tohave its own separate earth ground. We recommend you consultyour local approved electrician.• Elevated operating ambient temperatureThe maximum operating temperature of the system is 35°C (95°F).Careful consideration should be given to installing the system inan environment compatible with the 35°C (95°F) maximumambient temperature.• Reduced airflowThe amount of airflow required for the safe operation of theequipment should not be compromised when installing the systemin a rack.
