Installation environment

When installing your product, consider these factors:
• Ventilation
• Temperature
• Moisture
• Chassis load
Ventilation: Do not block any ventilation openings. Install in accordance with the
manufacturer’s instructions. Ensure that the location planned for the installation
of the unit is well ventilated.
Temperature: Consider the DVR 31’s operating temperature (32 to 104°F, 0 to
40°C) and humidity specifications (10 to 90% relative, noncondensing) before
choosing an installation location. Extremes of heat or cold beyond the specified
operating temperature limits may reduce the life expectancy of the DVR 31. Do
not install the DVR 31 on top of other hot equipment. Leave 1.75 inches (44 mm)
of space between rack mounted DVR 31 units.
Moisture: Do not use the unit near water. Moisture can damage the internal
components. To reduce the risk of fire or electric shock, do not expose this unit to
rain or moisture.
Chassis: Equipment weighing less than 35 lbs (15.9 kg) may be placed on top of
the DVR 31 only if the DVR 31 is placed on a shelf and not rack mounted.
Be sure to power off the unit before making any connections. In order to prevent
the unit from losing data and system damage that may be caused by sudden
power, use of an uninterruptible power supply is highly recommended.
Note: Do not remove the rubber feet, and always leave a space for air ventilation
on the unit’s bottom side.
