108 mm. Millimeter dimensions are always expressed in whole numbers.
WARNING!
An assembled enclosure (all components installed) weighs more than 29.5 kg (65 lb) and requires a
minimum of two individuals to move.
Environmental specifications
To ensure optimum product operation, you must maintain the operational environmental specifications
listed in Table 14. The ambient temperature (the enclosure air intake or room temperature) is especially
critical.
Table 14 Environmental operating specifications
Ambient temperature: +10°C to +35°C (+50°F to +95°F) with an average rate of change of 1°C/hour
maximum,andastepchangeof3°Corless.
Maintaining the ambient temperature within the specified range ensures that the internal operating
temperatures support the drive manufacturer’s specifications.
Relative humidity: 40% to 60% (noncondensing) with a step change of 10% or less (noncondensing)
Air quality: Not to exceed a maximum of 500,000 particles, 0.5 micron or larger, per cubic foot of air
Heat dissipation:1600BTUsperhour
