Pre-installation Inspection
Perform a visual inspection of the instrument when it is removed from the shipping
container. Check for shipping damage such as dents, scratches, distortion, and
damaged connectors.
Installation
The SmartWave unit is 8.75" (222 mm) high and is designed to be installed in a
standard 19" (483 mm) RETMA rack or a transit case; pem-nuts are provided for
mounting optional slides.
CAUTION!
Avoid blocking the instrument air intakes or exhaust.
2.5 Air Intake and Exhaust
The air intakes are located on the top and side panels of the instrument and the exhaust
is through the rear panel. Care must be taken not to block the side air intakes; the top
air intakes allow for improved cooling if this air is available. No special vertical
separation is required when stacking instruments. However, a 1.75" (45 mm) vertical
spacer above the instrument may improve cooling. The temperature of the intake air
should not exceed 113°F (45°C).
At full power the unit dissipates over 2250W with the PFC option. It is important that the
heat produced is properly vented to the exterior of the chassis. Special baffling to
control air flow may be required to prevent hot exhaust air being drawn into the intakes
if the unit is to be run continuously at full power.
The preferred mounting method for full power operation is bottom mounting. Slide
mounting may impair air flow from the side air intakes. If slides must be used, select
narrow slides to minimize restrictions to air flow and select cabinets without wide rails
which can block air flow.
Refer to Table 2–1 for the recommended slides and Figure 2–2 for the mounting
location.
Periodic cleaning is required to ensure that dust build-up within the chassis does not
restrict airflow through the modules, which could lead to overheating of the system. A
strong vacuum cleaner may be used to remove dust from the various assemblies within
the SW chassis. Compressed air is not recommended.
