The CW unit employs internal fans to circulate cooling air. The air is drawn
into the chassis along its sides, and is exhausted through the rear panel.
For maximum product life and reliability, do not allow the airflow to be
impeded.
CAUTION! Avoid blocking the instrument air
intakes or exhaust.
3.5 POWER IN CONNECTIONS
