Install/Air Flow: Maintaining service clearance allows proper air flow.
Service Clearances See 7014 Model T00 and T42 Rack for T00 or T42 rack
service clearances.
1. See page 202 for definitions of noise emissions positions. See noise emissions note 4.
2. Inrush currents occur only at initial application of power, no inrush occurs during normal
power off-on cycle.
3. The upper limit of the dry bulb temperature must be derated 1°C per 137 m (450 ft.) above
915 m (3000 ft.).
4. The upper limit of the wet bulb temperature must be derated 1°C per 274 m (900 ft. ) above
305 m (1000 ft.).
